Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. When a healthy heart beats, it makes a “lub-dub” sound. The first heart sound “lub”, also known as S1, is caused by the closing of the AV valves after the atria have pumped blood into the ventricles. The second heart sound “dub”, or S2, originates from the closing of the aortic and pulmonary valves, right after the ventricles have ejected the blood. The time interval between S1 and S2 is when the ventricles contract, called SYSTOLE. The interval between S2 and the NEXT S1 is when the ventricles relax and are filled with blood, called DIASTOLE. Diastole is longer than systole, hence the lub-dub, lub-dub, lub-dub… Heart sounds are auscultated at 4 different sites on the chest wall which correspond to the location of blood flow as it passes through the aortic, pulmonic, tricuspid, and mitral valves, respectively. This is how SIMILAR defects associated with DIFFERENT valves are differentiated. Heart murmurs are whooshing sounds produced by turbulent flow of blood. Murmurs are diagnosed based on the TIME they occur in the cardiac cycle, their changes in INTENSITY over time, and the auscultation SITE where they are best heard. Examples of conditions associated with common systolic murmurs include: - MITRAL valve regurgitation, when the mitral valve does NOT CLOSE properly and blood surges back to the left atrium during systole. The murmur starts at S1, when the AV valves close, and maintains the same intensity for the entire duration of systole. This holosystolic murmur is best heard at the mitral region -the apex, with radiation to the left axilla. Because the valve closure in mitral regurgitation is INcomplete, S1 is often quieter. On the other side of the heart, a TRICUSPID valve regurgitation has similar timing and shape, but it is loudest in the tricuspid area and the sound radiates up, along the left sternal border. - AORTIC valve stenosis, when the aortic valve does NOT OPEN properly and blood is forced through a narrow opening. The blood flow starts small, rises to a maximum in mid-systole at the peak of ventricular contraction, then attenuates toward the end of systole. This results in a crescendo-decrescendo, or a diamond-shaped, murmur which starts a short moment after S1. It is often preceded by an ejection click caused by the opening of the STENOTIC valve. Aortic stenosis murmur is loudest in the aortic area and the sound radiates to the carotid arteries in the neck following the direction of blood flow. Again, on the other side of the heart, a PULMONIC stenosis has the same characteristics but is best heard in the pulmonic area and does NOT radiate to the neck. Other conditions that cause audible systolic murmurs include ventricular septal defect and mitral valve prolapse. An example of diastolic murmurs is aortic valve regurgitation. This is when the aortic valve does NOT CLOSE properly, resulting in blood flowing back to the left ventricle during diastole- the filling phase. As the blood flows in the REVERSE direction, the murmur is best heard NOT in the aortic area, but rather along the left sternal border. It peaks at the beginning of diastole when the pressure difference is highest, then rapidly decreases as the equilibrium is reached. Other common diastolic murmurs are associated with pulmonic regurgitation, mitral stenosis and tricuspid stenosis.

2 Symptoms of a Leaking Heart Valve | Heart Disease

Watch more How to Understand Heart Disease videos: http://www.howcast.com/videos/512516-2-Symptoms-of-a-Leaking-Heart-Valve-Heart-Disease So, before we talk about what the symptoms are for a leaky heart valve, let's talk a little bit about what the heart valves are, and what their function is in the heart. The heart valves are doors in the heart that are supposed to open widely and let blood flow in one direction of the heart, and then close tightly, without letting any back flow, or regurgitation, what we call leakiness in the heart. Leaky heart valves are not uncommon. They can be caused by several things. Some are deteriorations over time, and people with heart valves that were abnormal from birth, and others are things that are picked up along the way, like infections that can attack the heart valve, or a buildup of atherosclerosis that can cause calcification, or thickening of those heart valves. There are four main valves in the heart. For the most part, symptoms usually come when one of the two left-sided heart valves have a problem. Your doctor is usually able to pick this up when they listen to your heart with a stethoscope and hear what we call a murmur, or abnormal heart sound. Once your doctor identifies the murmur, he or she will send you for further imaging. Most often, we use cardiac ultrasound to take a good picture of the heart and see how the valves are functioning. We have waves on the cardiac ultrasound to tell us the heart valves are too leaky or too stiff and whether or not they're functioning well overall. When valves don't function properly, they can do one of two things. They can either be pretty tight, or stenotic, or leaky, or regurgitant. Either one can lead to some symptoms. Those symptoms would be shortness of breath when you exert yourself, or lower extremity swelling, or edema. Usually, they come on pretty gradually and you would notice an increase of symptoms over time such as the lack of ability to walk up a flight or two of stairs, something you might have been able to do just a few months or a year before. The other thing would be increased swelling in the legs. And you might notice at the end of a long day that your legs are more swollen than they used to be. These are the two main signs of a leaky or tight heart valve. For the most part, leaky heart valves show up as an inability to exert yourself, shortness of breath, or swelling of your feet or legs. The main heart valves which can be leaky would be the left-sided heart valves, which we call the aortic valve or the mitral valve. And that's what you really need to know about a leaky heart valve.

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Blood pressure is the force the circulating blood EXERTS on the walls of blood vessels. It is different in different types of vessels, but the term ”blood pressure”, when not specified otherwise, refers to ARTERIAL pressure in the SYSTEMIC circulation. When the heart contracts and pumps blood into the aorta, during systole, the aortic pressure RISES, and so does the systemic arterial pressure. The maximum pressure following an ejection is called the SYSTOLIC pressure. In between heart beats, when the ventricles refill, blood pressure FALLS to its lowest value called the DIASTOLIC pressure. THESE are the 2 numbers on a blood pressure reading. Blood pressure normally shows a daily pattern and is usually lower at night. During day-time, it fluctuates with physical activities and emotional states. Hypertension refers to a PERSISTENT HIGH blood pressure. In the US, high blood pressure used to be defined as greater than 140/90, but recent guidelines have changed these values to 130/80 to better prevent and treat the condition. Normal blood pressure is BELOW 120/80. In practice, blood pressure is considered TOO low ONLY if it produces symptoms. Hypertension does NOT cause symptoms on its own, but it slowly DAMAGES blood vessels, and in the long-term, is a MAJOR risk factor for a variety of cardiovascular diseases such as stroke, aneurysm and heart attack; as well as end organ damage such as renal failure or vision loss. For this reason, hypertension is known as the “SILENT killer”. Hypertension can be classified as primary or secondary, with the former being responsible for over 90% of cases. Primary hypertension has NO apparent cause and may develop as a result of old age, obesity, high-salt diet, lack of exercise, smoking and drinking. Most commonly, the blood vessels are hardened with age or unhealthy diets, making it harder for blood to flow. Secondary hypertension, on the other hand, is caused by an underlying condition. Many conditions and factors can cause hypertension; most notable are kidney problems and endocrine disturbances. Regardless of the cause, the INcrease in blood pressure is produced by EITHER an INcrease in vascular resistance - narrower or stiffer blood vessels; OR an INcrease in cardiac output – larger volume of blood pumped out by the heart. These 2 factors are the targets of antihypertensive drugs. Treatments must start with life style changes such as healthy, low-sodium diets, physical exercise and stress management. On top of that, antihypertensive agents may be used to control hypertension. These include: - Vasodilators: these drugs DILATE blood vessels, thereby DEcreasing vascular resistance and reducing blood pressure. - Diuretics: diuretics promote sodium and water removal by the kidneys and thereby DEcrease blood volume. - Drugs that DEcrease cardiac output by decreasing heart rate or contractility, may also be used to treat hypertension.

All rights reserved. Voice by: Sue Stern. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, and vice versa. For example, during physical exercises, the heart beats faster to put out more blood in response to higher demand of the body. It is noteworthy that the ventricles do NOT eject ALL the blood they contain in one beat. In a typical example, a ventricle is filled with about 100ml of blood at the end of its load, but only 60ml is ejected during contraction. This corresponds to an EJECTION fraction of 60%. The 100ml is the end-DIASTOLIC volume, or EDV. The 40ml that remains in the ventricle after contraction is the end-SYSTOLIC volume, or ESV. The stroke volume equals EDV minus ESV, and is dependent on 3 factors: contractility, preload, and afterload. Contractility refers to the force of the contraction of the heart muscle. The more forceful the contraction, the more blood it ejects. PRELOAD is RELATED to the end-diastolic volume. Preload, by definition, is the degree of STRETCH of cardiac myocytes at the end of ventricular filling, but since this parameter is not readily measurable in patients, EDV is used instead. This is because the stretch level of the wall of a ventricle INcreases as it’s filled with more and more blood; just like a balloon - the more air it contains, the more stretched it is. According to the Frank-Starling mechanism, the greater the stretch, the greater the force of contraction. In the balloon analogy, the more inflated the balloon, the more forceful it releases air when deflated. AFTERLOAD, on the other hand, is the RESISTANCE that the ventricle must overcome to eject blood. Afterload includes 2 major components: - Vascular pressure: The pressure in the left ventricle must be GREATER than the systemic pressure for the aortic valve to open. Similarly, the pressure in the right ventricle must exceed pulmonary pressure to open the pulmonary valve. In hypertension for example, higher vascular pressures make it more difficult for the valves to open, resulting in a REDUCED amount of ejected blood. - Damage to the valves, such as stenosis, also presents higher resistance and leads to lower blood output.

Baroreflex Regulation of Blood Pressure, Animation.

How heart rate is controlled by the parasympathetic and sympathetic divisions of the autonomic nervous system, with overview of baroreceptor resetting. This video (updated with real voice) and other related images/videos (in HD) are available for instant download licensing here : https://www.alilamedicalmedia.com/-/galleries/images-videos-by-medical-specialties/neurology ©Alila Medical Media. All rights reserved. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia Baroreflex, or baroreceptor reflex, is one of the mechanisms the body uses to maintain stable blood pressure levels or homeostasis. Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood pressure to normal levels. The reflex starts with specialized neurons called baroreceptors. These are stretch receptors located in the wall of the aortic arch and carotid sinus. Increased blood pressure stretches the wall of the aorta and carotid arteries causing baroreceptors to fire action potentials at a higher than normal rate. These increased activities are sent via the vagus and glossopharyngeal nerves to the nucleus of the tractus solitarius – the NTS - in the brainstem. In response to increased baroreceptor impulses, the NTS activates the parasympathetic system – the PSNS - and inhibits the sympathetic system – the SNS. As the PSNS and SNS have opposing effects on blood pressures, PSNS activation and SNS inhibition work together in the same direction to maximize blood pressure reduction. Parasympathetic stimulation decreases heart rate by releasing acetylcholine which acts on the pacemaker cells of the SA node. Inhibition of the sympathetic division decreases heart rate, stroke volume and at the same time causes vasodilation of blood vessels. Together, these events rapidly bring DOWN blood pressure levels back to normal. When a person has a sudden drop in blood pressure, for example when standing up, the decreased blood pressure is sensed by baroreceptors as a decrease in tension. Baroreceptors fire at a lower than normal rate and the information is again transmitted to the NTS. The NTS reacts by inhibiting parasympathetic and activating sympathetic activities. The sympathetic system releases norepinephrine which acts on the SA node to increase heart rate; on cardiac myocytes to increase stroke volume and on smooth muscle cells of blood vessels to cause vasoconstriction. Together, these events rapidly bring UP blood pressure levels back to normal. Baroreflex is a short-term response to sudden changes of blood pressure resulted from everyday activities and emotional states. If hypertension or hypotension persists for a long period of time, the baroreceptors will reset to the “new normal” levels. In hypertensive patients for example, baroreflex mechanism is adjusted to a higher “normal” pressure and therefore MAINTAINS hypertension rather than suppresses it.

Is It Okay to Do Keto & Intermittent Fasting If You Have a Heart Condition?
 
03:27
Take Dr. Berg's Free Keto Mini-Course: http://pxlme.me/-i717vtY or go here: https://www.drberg.com/how-to-do-ketosis Download Keto Essentials https://m.me/drericberg?ref=w2128577 Dr. Berg talks about if it's okay to do ketogenic diet and intermittent fasting if you have a heart condition. In the chain of events of developing a heart condition you first get damage to the lining of the arteries. Cholesterol will then come in and start to heal it. The arteries become stiff and then you get the high blood pressure. We then get put on a statin, which is given a black label - because it causes diabetes which increases your risk of heart disease. And the blood pressure meds (thiazides and beta blockers) contribute to insulin resistance further causing the problem. Recently I had a question from someone who wanted to know if is it okay to do ketogenic diet and intermittent fasting if you have a heart condition, this is a big fat yes. In fact you will get a heart condition if you don’t do ketogenic diet and intermittent fasting and if you are going to do a typical high carbs you would get a heart problems. Let’s talk about why. Because in a chain of events that occurs before you get the buildup of cholesterol there is always a damage to epithelial lining on the inside of the arteries and what damages is that is high blood sugar and high insulin. Those two things will damage the wall, the cholesterol comes in as a band aid, same thing with the calcium and protein fibrin that comes in the artery to help heal it, it is not the bad guy it is just there to help heal it and then the person consuming too many carbohydrates they are going to have high cholesterol because those turn into sugar and those sugar converted into high cholesterol and you would take a drug for that and lower it called the statin but the problem with statins is it causes insulin resistance and more insulin so it keeps feeding itself. But then what happens is the arteries get stiff, calcium builds up and then you don’t have the elasticity so there goes the high blood pressure and then there is diuretic drug that we can put you on. The problems with diuretics is they deplete potassium also they will increase insulin and could cause insulin resistance as well. So it feeds itself as well, if you don’t have enough potassium, it is really hard to fix this blood sugar problems because people with high blood sugar and insulin resistance always have the potassium deficiency in the first place and by taking potassium you can actually improve that condition and stabilize blood sugars a lot better and the blood sugar and insulin problem will also cause high blood pressure because it is gonna harden the arteries and make the arteries in elastic so there is no expansion but no problem because we can put you in a diuretic to reduce the blood volume and the pressure should come down because it increases your risk for insulin resistance therefore it causes more insulin and propelling the problem further and also it creates the deficiency of potassium which you need to actually fix insulin resistance.

Heart Valve Disease Symptoms and Causes
 
02:34
Some people with heart valve disease might not experience symptoms for many years. Signs and symptoms of heart valve disease may include: Abnormal sound (heart murmur) when a doctor is listening to the heart beating with a stethoscope Fatigue Shortness of breath, particularly when you have been very active or when you lie down Swelling of your ankles and feet Dizziness Fainting Irregular heartbeat When to see a doctor If you have a heart murmur, your doctor may recommend you visit a cardiologist. If you develop any symptoms that may suggest heart valve disease, see your doctor. Causes Your heart has four valves that keep blood flowing in the correct direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (leaflets or cusps) that open and close once during each heartbeat. Sometimes, the valves don't open or close properly, disrupting the blood flow through your heart to your body. Heart valve disease may be present at birth (congenital). It can also occur in adults due to many causes and conditions, such as infections and other heart conditions. Heart valve problems may include: Regurgitation. In this condition, the valve flaps don't close properly, causing blood to leak backward in your heart. This commonly occurs due to valve flaps bulging back, a condition called prolapse. Stenosis. In valve stenosis, the valve flaps become thick or stiff, and they may fuse together. This results in a narrowed valve opening and reduced blood flow through the valve. Atresia. In this condition, the valve isn't formed, and a solid sheet of tissue blocks the blood flow between the heart chambers. Risk factors Several factors can increase your risk of heart valve disease, including: Older age History of certain infections that can affect the heart History of certain forms of heart disease or heart attack High blood pressure, high cholesterol, diabetes and other heart disease risk factors Heart conditions present at birth (congenital heart disease) Complications Heart valve disease can cause many complications, including: Heart failure Stroke Blood clots Heart rhythm abnormalities Death

Blood from the upper body returns via the superior vena cava, blood from the lower body returns via the inferior vena cava. The rate of venous return is determined by two factors: the pressure gradient between venous pressure and right atrial pressure; and venous resistance. A decrease in right atrial pressure leads to an increase in venous return, and vice versa. Breathing is one of the mechanisms that facilitate venous return. This is known as thoracic pump, or respiratory pump. During inspiration, the diaphragm moves down, expanding the thoracic cavity, resulting in a decreased intra-thoracic pressure and a subsequent expansion of the lungs. Part of this change in pressure is transmitted across the walls of the heart, lowering right atrial pressure and thus facilitating venous return. Another aspect of the diaphragmatic descent is the concomitant increase in abdominal pressure. As the inferior vena cava passes through both abdominal and thoracic cavities, an increase in abdominal pressure together with a decrease in thoracic pressure squeeze the blood upward - toward the heart. On the other hand, left ventricular stroke volume is decreased during inspiration. This is because the expansion of the lungs causes pulmonary blood volume to increase and the blood flow from the lungs to the left atrium to decrease. During expiration, the diaphragm moves up, the pressure in the thoracic cavity reverses. Venous return decreases. Pulmonary blood vessels shrink pumping more blood through the pulmonary veins into the left atrium. Stroke volume increases as a result.

How to Treat heart murmur in baby 4 months |Adult Heart Murmur
 
03:25
How to Treat heart murmur in baby 4 months |Adult Heart Murmur Heart murmurs are unusual sounds that the blood makes as it is pumped through your heart. Some heart murmurs are innocent heart murmurs and are not indicative of a condition requiring treatment. Other heart murmurs, however, are abnormal and may require monitoring or treatment 1 Take medications if your doctor prescribes them. The medication you are prescribed may vary depending on your particular condition and medical history. Commonly used medications include:[18] Anticoagulants. These medications reduce blood clots. They reduce the likelihood that a blood clot will form in your heart or brain causing a heart attack or stroke. Common medications include aspirin, warfarin (Coumadin, Jantoven) and clopidogrel (Plavix). Diuretics. These medications are used to lower blood pressure, which can reduce the heart murmur. They prevent you from retaining too much water in your body. Angiotensis-converting enzyme (ACE) inhibitors. These medications lower blood pressure, and by doing so, can improve your heart murmur. Statins. These medications lower cholesterol. High cholesterol can aggravate problems with valves. Beta blockers. Beta blockers make your heart beat slower and reduce your blood pressure. This can lessen the murmur. 2 Repair a damaged or leaking valve. Medications can lower the physical stress on your valves, but if you have a valve that needs to be repaired, it would have to be done through surgery. There are several ways your doctor might do this:[19][20] Balloon valvuloplasty. During this procedure the doctor uses a balloon on the end of a catheter to widen valves that have become too narrow. When the balloon is located at the narrow point, the balloon is expanded. The pressure makes the valve wider. Annuloplasty. The surgeon reinforces the area around the valve by inserting a ring. This is used to repair an abnormal opening. Surgery on the valve itself or the supporting tissues. This can repair valves that don’t close properly. 3 Replace a faulty valve. If it is not possible to repair the valve that you have, your doctor may suggest replacing it with an artificial valve. This can be done in several ways:[21] Open-heart surgery. Depending on your situation, your doctor may recommend replacing a valve with either a mechanical valve or a tissue valve. Mechanical valves are long lasting, but increase your risk of blood clots. If you have a mechanical valve you would need to take blood-thinning medications for the rest of your life to reduce your risk of heart attacks and strokes. Tissue valves use material from a pig, cow, organ donor, or your own tissue. The drawback is that tissue valves may need to be replaced as they usually don’t last as long. The advantage is that these valves don’t absolutely need long term blood thinners. A transcatheter aortic valve replacement. This procedure doesn’t require open-heart surgery. Instead the new valve is inserted with a catheter. The catheter is inserted elsewhere in your body, such as the leg, and used to bring the valve to your heart.

Pregnancy can cause strange heart symptoms
 
02:38
Your pregnant. And you feel like your heart is racing. Is that normal? WATCH: How you can stay heart-healthy while pregnant IFrame WellStar Kennestone cardiologist Dr. Mindy Gentry says the answer, typically, is yes. "So very commonly, pregnant women will come in with palpitations, or feeling like their heart is beating fast and hard," Dr. Gentry says. "And oftentimes that's because it is. Your heart rate is naturally higher during pregnancy. A woman's blood volume goes up by about 30% to 50% during pregnancy, and her heart rate may increase by 10 to 20 beats a minute, Dr. Gentry says. But, less than 10% of the time, Dr. Gentry says, hormonal changes that come with pregnancy, can bring on or exacerbate an abnormal heart rhythm. "So when people come in complaining of high heart rate or palpitations, we have to decide is that normal, related to the pregnancy, or is it an abnormal rhythm that has been worsened or exacerbated by the pregnancy," Gentry says. Many women experience a drop in their blood pressure when they're expecting, which can cause dizziness and lightheadedness, "So, trying to hydrate well, and making sure you stay hydrated is very important, to try to keep that blood pressure from dropping low enough that it causes problems," Gentry says. Some pregnant women have the opposite problem, hypertension. Their blood pressure is too high. That's often known as preeclampsia. Pregnant woman can also experience a spike in their blood sugar, or gestational diabetes. "Either of those things does increase the risk of developing cardiovascular disease after pregnancy, and really for decades after the pregnancy," says Gentry. "If you're overweight, or not exercising, that increases the risk significantly." For that reason, Dr. Gentry says, try to get as healthy as you can and to start exercising before you start trying to get pregnant. Then, stay active as long as you safely can into your pregnancy. If something just doesn't feel normal, get it checked out. NEXT ARTICLE: Tired all the time? You may be low on vitamin B12

Protandim Nrf2 Testimony - Heart Disease, Diabetes, Migraines, Arthritus
 
10:09
I Am so honored to share our Nrf2 stories with you. Nrf2 is an Ascension Tool Product! Detox your body by taking only one enzyme activating anti aging pill for less than $2 bucks a day. My grey hairs have almost completely disappeared! Helped my restless leg syndrome, body pain, and extremely lessened the hot flashes, migraines, and menopausal symptoms. I Am a much happier woman. My dad's testimony in writing.... I have been diagnosed for about 5 years now for a heart murmur and was told that at some point I would have to have an open heart surgery for valve replacement. I also have had chronic high blood pressure though out my life requiring constant medication. My cardiologist in Fairbanks was preparing me for open heart surgery for the winter of 2015. My daughter Shawn begged me to start taking Protandim Nrf2 saying that it has been scientifically proven to help with heart disease and what would it hurt. Relying on Shawn's judgment and her own powerful story of it helping her with her debilitating migraines, I decided to try it July of 2015. In Oct 2015 a new cardiologist that I saw in Tuscon told me that I was not yet ready for the surgery. My heart was strong and see me again in March. Following the March exam the cardiologist told me that my heart was still doing fine! He also said that I would know when I was ready for the surgery from severe fatigue and exhaustion. Here I am Sept 2016 mowing my lawn, going for long dog walks, and being a 24/7 caretaker for my wife - with sustained energy. Do I feel like I'm 25? No, but at 74 I feel good and my blood pressure is now controlled like it has never been before. I will update you on my next heart exam in 0ct 2016! My wife Tamara is diabetic, mobility impaired, and suffering from pretty significant (undiagnosed) short term memory loss. I went ahead and started Tamara on the product shortly after I started Protandim - again thinking what could it hurt. Having been on the product for about two months, we ran out and missed about a weeks worth of taking Protandim. Then with a shock that her short term memory loss issue had returned I realized for the past two months we were living a nearly normal life having normal conversations with each other. After getting on back on the product her memory issues again improved. After that I try to never again run out! Then following blood tests and a recent visit to her doctor Sept 2016, her diabetic A1C level had returned to normal, her blood pressure and cholesterol was normalized and her doctor took her off of both of these medications. Pretty amazing! Now the dog....Last year our King Charles Cavalier Spaniel Kashi developed a serious limp. In May of 2016 Shawn gave us 5 Canine Health Protandim pills and we noticed immediate improvement with her limp. We used up the 5 pills and that same month returned to Fairbanks. Kashi's limp came back and after a vet visit summer of 2016, she was diagnosed with arthritis and given expensive doggie arthritis medication. Following that visit I ordered her a bottle of Canine health and within a few days I noticed her arthritis improving and stopped the vet prescribed medicine (which helped the pain but did not help the limp). After Canine Health her limp completely went away after a week or so and we are back to our long doggie walks limp free! I highly recommend this Protandim and I am thankful that Shawn introduced me to this product. Shawn's Dad - Darrel Zuke Oct 2016 update - My Dad went to his Cardiologist visit today in Tucson and came back with the greatest of news! His test for his valve restriction results had maintained the same levels as his last test that was taken in March, holding steady :) This is the first doc visit where his valve restriction test did not decrease in a 6 month period. His open heart surgery is postponed once again!!!!!! Apr 2017 update - Doctor visit. Heart is exactly the same as his last visit! Stable! Apr 2018 - Doctor didn't feel the need to test and sent me out the door!

The two biggest killers today are cancer and heart disease. Millions are diagnosed with heart diseases each year, and though it may seem unavoidable, there are actually healthy ways to prevent a sick heart. Did you know that there is a clear way to have a healthy heart? You start with more oxygen, which in turn strengthens the blood, and with healthy blood, you have a healthy heart! So how can we add more oxygen to our blood? We all know that exercise is part of the 8 laws of health, but did you know there is a specific type of exercise that is especially good for our blood, and in turn our hearts?

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Tetralogy of Fallot, or TOF, is a CONGENITAL heart disease, classically known as a combination of FOUR defects that disrupt the normal blood flow in the heart. In normal circulation, oxygen-poor blood from the body returns to the right side of the heart where it is pumped into the pulmonary artery and to the lungs. After being oxygenated, oxygen-RICH blood from the lungs returns to the left side of the heart to be pumped into the aorta and out to the body. Infants born with TOF are presented with 4 major structural defects: - NARROWING of the PULMONARY output - Ventricular septal defect: an OPENING in the interventricular septum - Displacement of the aorta: it now connects to both ventricles and - Hypertrophy of the right ventricle The 4 defects, however, are likely the result of a SINGLE incident during embryonic development – the MAL-alignment of the upper part of the ventricular septum, known as the conal septum, with the rest of it. As the conal septum moves rightward and anteriorly, it creates an opening in the septum; blocks the right ventricular outflow tract; and pulls the aorta over the ventricular septum. Finally, because the output to the lungs is obstructed, the right ventricle develops thicker muscle to push harder, resulting in right ventricular hypertrophy. The cause of TOF remains largely unknown but several genetic disorders and prenatal factors are thought to be associated with increased risks of this condition. Connected ventricles in TOF allow blood to flow from one side to the other. The DIRECTION of this flow, however, depends on the DEGREE of pulmonary tract obstruction. When the obstruction is minimal, the flow is LEFT-to-RIGHT, because the LEFT ventricular pressure is usually HIGHER. While some of the already oxygenated blood leaks back to the lungs, most of it goes the usual route to the aorta, and the baby appears “pink” as normal. However, in the long-term, if too much blood flows to the lungs, patients may develop congestive heart failure. On the other hand, when pulmonary stenosis is severe, blood in the right ventricle has to escape through the septal defect during ventricular contraction, and a RIGHT-to-LEFT shunt results. The MIXED blood, which is LOW in oxygen, is then pumped into the aorta and to the body, causing oxygen deprivation in body's tissues, or hypoxia. This may result in a BLUISH skin color, known as CYANOSIS. The greater the pulmonary obstruction, the more deoxygenated blood enters the systemic circulation, the more severe the symptoms. Children with TOF may develop acute episodes of hypoxia, known as "tet spells", during activities that demand more oxygen. These episodes are characterized by: shortness of breath, increased cyanosis, loss of consciousness, and may result in hypoxic brain injury and death. Tet spell is a medical emergency but simple procedures such as squatting and the knee chest position, which increase systemic vascular resistance and therefore decrease right-to-left shunting, can help to temporarily relieve symptoms. Diagnosis is by echocardiography and can be done prenatally. Treatment is usually by repair surgery within the first year of life. The surgery involves enlargement of the pulmonary tract and closure of the septal defect.

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Ventricular septal defect, or VSD, refers to an OPENING in the interventricular septum that separates the two ventricles of the heart. In normal circulation, oxygen-poor blood from the body returns to the RIGHT side of the heart where it is pumped into the pulmonary artery and to the lungs. After being oxygenated, oxygen-rich blood from the lungs returns to the LEFT side of the heart to be pumped into the aorta and out to the body. A VSD allows ABnormal blood flow between the two ventricles. The NET flow of blood, called a SHUNT, is usually from LEFT to RIGHT due to significantly HIGHER blood pressure in the LEFT side of the heart. This is because the left side has to pump blood all over the body while the right side only needs to send it to the lungs. If the defect is small, the shunt is negligible and does not result in any symptoms. A large defect, on the other hand, may OVERLOAD the right side of the heart, causing it to FAIL. Heart failure symptoms usually appear during the first few weeks of life and include: fatigue, shortness of breath, difficulty feeding and poor growth. Without treatment, other complications may also occur. As the right ventricle continuously pumps MORE blood to the lungs, the entire pulmonary vasculature may be overloaded and pulmonary HYPERtension may result. To OVERCOME the high pressure in the lungs, the right ventricle has to generate even HIGHER pressure, which eventually becomes GREATER than that of the LEFT ventricle. This REVERSES the direction of the shunt, causing oxygen-POOR blood to flow from RIGHT to LEFT and be sent to all tissues of the body. The resulting oxygen DEPRIVATION may be seen as a BLUISH skin color, known as CYANOSIS. A VSD can happen alone or in combination with other congenital defects in conditions such as Down syndrome, or tetralogy of Fallot. The cause is unknown but likely to involve both genetic and environmental factors. The turbulence of abnormal blood flow in VSD produces heart murmurs, which can be heard using a stethoscope. Diagnosis is confirmed by echocardiography. VSD is the most common congenital heart defect in infants, but the defect is small in most cases. Small defects usually close on their own in early childhood and no treatment is needed. Large defects that produce symptoms usually require surgical closure in the first year of life.

USMLE Cardiovascular 7: Blood Pressure,  Pulse Pressure, and Baroreceptors
 
15:19
https://youtu.be/rpL0NEi_tEY RAAS Pathway video Welcome to LY Med, where I go over everything you need to know for the USMLE STEP 1, with new videos every day. Follow along with First Aid, or with my notes which can be found here: https://www.dropbox.com/sh/xisbr5u8reifaqk/AAAEWF-Ho2r0OJMooCYN_bG-a?dl=0 This video is on the physiology of blood pressure, pulse pressure and baroreceptors! Blood pressure measures the pressure your blood exerts on your blood vessels. During systole, the ventricles contract and push that blood into your vessels, which we can measure via the systolic blood pressure. In diastole, the heart relaxes, and the pressure drops and this is measured via the diastolic blood pressure. Now your BP is highly regulated and depends on your cardiac output. Do you recall what makes up our CO? This includes heart rate and stroke volume (which can further be divided into preload, afterload, and contractility). Preload is filling, and increased filling/fluid increases blood pressure. This is the basis behind why we give IV fluids in hypotensive patients! In fluid overloaded hypertensive patients, we may give anti-hypertensives to get rid of some of this fluid in the form of diuretics. Afterload directly relates to resistance and pressure. The largest way to increase afterload is by decreasing the diameter, or lumen size of your blood vessels. THis increases blood pressure. Meanwhile, in vasodilation, you increase the lumen and decrease pressure. Contractility plays a role in BP as you can pump more blood out. Sympathetic and parasympathetic control really plays a role here, in particular beta 1 receptors. Your body modulates these factors automatically, making sure your blood pressure is appropriate to the situation. Some pathways include the RAAS system and your heart releasing ANP and BNP. Another mechanism is through baroreceptors. These are mechanoreceptors that sense pressure. There are two: Carotid baroreceptors: located in the carotid sinus, these link up to the glossopharyngeal nerve (CN IX) Aortic arch baroreceptor: seen in the aorta, these link up to the vagus nerve (CN X). Both ultimately transmit to the solitary nucleus of the medulla. What is the physio behind these receptors? Well, when there is increased blood pressure, that stretches these muscles and receptors and causes depolarization. The more they stretch, the more they depolarize and fire. Your brain senses this as increased BP and will try to lower the sympathetic fight or flight response. You can stimulate this with a carotid massage! Conversely, if you have low BP, there will be less stretch and firing. Your body will notice this as low pressure and will try to compensate by increasing sympathetic firing! That is how your baro receptors work! Our last topic will be on pulse pressure. Pulse pressure is the difference between the systolic pressure and diastolic. Pulse pressure is proportionate to cardiac output, stroke volume, and ventricular compliance. The more blood you're able to pump out, the more your pulse pressure. Increased pulse pressure is seen in exercise, hyperthyroidism, aortic regurgitation, and aortic stiffening. Decreased pulse pressure is seen in low systolic pressure and volume. This is seen in aortic stenosis, cardiogenic shock, cardiac tamponade, and heart failure. Done with this video. In our next video, we will discuss hypertension and related pathology and pharmacology. See you then!

Systolic murmur in mitral regurgitation
 
00:12
Mitral regurgitation — The holosystolic murmur of MR is high pitched and best heard with the diaphragm of the stethoscope and the patient in the left lateral decubitus position . Radiation depends upon the murmur intensity, which may be variable. The direction of radiation follows the direction of the regurgitant jet into the left atrium. ●When the jet is directed posterolaterally, the apical holosystolic murmur radiates toward the left axilla, inferior angle of the left scapula, and over the thoracic spine . In some patients, a loud murmur may be transmitted up the spine and sometimes to the top of the head. ●The murmur radiates toward the base and root of the neck if the regurgitant stream is directed anteromedially against the interatrial septum near the base of the aorta. Thus, it can be confused with the murmur of aortic stenosis or obstructive hypertrophic cardiomyopathy. The character of the carotid pulse and the behavior of S2 provide important clues to the diagnosis. Associated physical findings may help to characterize the nature and severity of MR, although with significant limitations. A more benign overall examination is suggestive of less severe MR and primary valve disease. Abnormalities (eg, S3, an accentuated P2, or a displaced apical impulse) are less helpful, since they can occur with primary valve disease, secondary MR, or a separate cardiac or pulmonary abnormality. The value and limitations of associated physical findings in a patient with MR is illustrated by the following: ●The absence of an S3 and cardiac enlargement suggest hemodynamically insignificant chronic MR. In contrast, clinical evidence of pulmonary hypertension (accentuated P2, right ventricular systolic hypertension) and right-sided heart failure are almost always associated with significant MR, provided no other cause of pulmonary hypertension coexists. ●A normal or hyperdynamic LV apical impulse suggests normal LV systolic function, and therefore primary MR. However, a displaced or sustained apical impulse may occur with either primary or secondary MR. ●In patients with either severe primary MR or a dilated cardiomyopathy with secondary (functional) MR, there may be an S3 gallop due to the high antegrade flow across the mitral valve, and findings of pulmonary hypertension and right heart failure. However, in dilated cardiomyopathy, S3 and findings of pulmonary hypertension may be present with mild or insignificant MR.

High blood pressure miracle healing - John Mellor International Australian Healing Evangelist
 
01:13
High blood pressure miracle healing in Auckland - John mellor Australian Healing Evangelist. http://www.johnmellor.org These miracles & healings happen because of the reality of Jesus Christ. The Bible says that Jesus is the Son of God and that the only way to eternal life is to believe in Jesus and accept Him into your life. Jesus came to earth as a man to buy back what was lost when Adam & Eve disobeyed God and fell from paradise in the Garden of Eden to Earth, and sin entered the world. Jesus' sacrifice on the cross broke the power of sin. Whoever believes in Jesus and repents of their sin will be forgiven and have eternal life: Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me." John 14:6 If you declare with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. Romans 10:9 About miracles, the Bible records Jesus commissioning His followers to use His name to heal the sick: He said to them, "Go into all the world and preach the gospel to all creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well." Mark 16:15 If you would like to open your heart to Jesus, say this prayer aloud: Prayer to open your life to Jesus and have an eternal home in heaven Lord Jesus, I open my heart to You and ask You to come into my life. I believe that You are the Son of God and that You died on the cross for my salvation, healing and forgiveness and that You rose again from the dead. Lord, I ask You to forgive all of my sins. I thank You, Jesus, for forgiving me, healing me and giving me an eternal home in heaven. I declare that You are my Lord, Jesus. Please guide me in every area of my life. Thank You for hearing my prayer. Amen. I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your impurities and from all your idols. I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws. (Ezekiel 26:25-27)

All rights reserved. Voice by: Sue Stern. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The cycle is initiated with the firing of the SA node that stimulates the atria to depolarize. This is represented by the P-wave on the ECG. Atrial contraction starts shortly after the P-wave begins, and causes the pressure within the atria to increase, FORCING blood into the ventricles. Atrial contraction, however, only accounts for a FRACTION of ventricular filling, because at this point, the ventricles are ALREADY almost full due to PASSIVE blood flow DOWN the ventricles through the OPEN AV valves. As atrial contraction completes, atrial pressure begins to FALL, REVERSING the pressure gradient across the AV valves, causing them to CLOSE. The closing of the AV valves produces the first heart sound, S1, and marks the beginning of SYSTOLE. At this point, ventricular depolarization, represented by the QRS complex, is half way through, and the ventricles start to contract, RAPIDLY building UP pressures inside the ventricles. For a moment, however, the semilunar valves remain closed, and the ventricles contract within a CLOSED space. This phase is referred to as isovolumetric contraction, because NO blood is ejected and ventricular volume is UN-changed. Ventricular ejection starts when ventricular pressures EXCEED the pressures within the aorta and pulmonary artery; the aortic and pulmonic valves OPEN and blood is EJECTED out of the ventricles. This is the RAPID ejection phase. As ventricular repolarization, reflected by the T-wave, begins, ventricular pressure starts to FALL and the force of ejection is REDUCED. When ventricular pressures drop BELOW aortic and pulmonary pressures, the semilunar valves CLOSE, marking the end of systole and beginning of diastole. Closure of semilunar valves produces the second heart sound, S2. The first part of diastole is, again, isovolumetric, as the ventricles relax with ALL valves CLOSED. Ventricular pressure drops RAPIDLY but their volumes remain UNchanged. Meanwhile, the atria are being filled with blood and atrial pressures RISE slowly. Ventricular FILLING starts when ventricular pressures drop BELOW atrial pressures, causing the AV valve to open, allowing blood to flow DOWN the ventricles PASSIVELY.

Wow 50%! Do you know anyone that has heart related problems, if so, please share this information. * High Blood Pressure * Heart Disease * Diabetes * Sexual Dysfunction * Dementia * Alzheimer's * Chronic Pain * Migraine Headaches * Arthritis * Depression * Menopause * Multiple Sclerosis * Kidney Issues * Lack of Energy ... The nitric oxide derived from arginine is directly or indirectly implicated in practically every cellular response and health condition imaginable, from the cardiovascular system to the immune system, and hormone function to nerve function. Although an exhaustive list of possible applications for the amino acid is not included, the following are the primary scientifically backed reasons that anyone -- even healthy people -- should consider adding the arginine to their health and wellness regimen. -ProArgi9 Plus is one thousand times more powerful than any naturally occurring antioxidant in the body. Arginine`s antioxidant properties support various body system and may protect against heart disease, stroke, cancer, and diabetes, as well as slowing premature aging. -ProArgi9 Plus offers wide-ranging cardiovascular support, including controlling blood pressure and plaque formation. Nitric oxide keeps arteries relaxed and pliable for normal blood pressure, preventing hypertension and angina. -ProArgi9 Plus enhances memory, particularly long-term memory, and may help to reverse the effects of dementia and Alzheimer's disease. -ProArgi9 Plus boosts human growth hormone (HGH) production, which has anti-aging properties. -ProArgi9 Plus enhances communication of messenger cells between nerves and the brain. -ProArgi9 Plus may help improve immune function and fight bacterial infections. -ProArgi9 Plus may help in the treatment and prevention of diabetes since many disease complications, including poor circulation and blindness, are vascular in nature. Arginine is also found to regulate insulin secretion in the pancreas. -ProArgi9 Plus may inhibit the division and proliferation of cancer cells. -ProArgi9 Plus helps with cholesterol control by lowering serum and LDL cholesterol levels. -ProArgi9 Plus enhances male sexual performance by treating vascular erectile dysfunction (ED). One in three men have this problem. -ProArgi9 Plus anticoagulant abilities reduce clotting to lower heart attack and stroke risk. -ProArgi9 Plus reduces pregnancy-related hypertension, a risk factor for both the expecting mother and the unborn child. -ProArgi9 Plus is useful in the treatment of asthma by opening pulmonary pathways for easier breathing and the treatment of lung disorders. -ProArgi9 Plus relaxes hypertonic sphincter muscles, preventing and healing hemorrhoids. -ProArgi9 Plus boosts lean muscle mass and preserves bone density by encouraging HGH production, which also leads to a reduction in fatty tissue. Because af these properties, it may be useful in weight management and strength training. -ProArgi9 Plus can help offset cardiovascular and lung damage caused by tobacco use, since nitric oxide levels in smokers are less than half of those found in non-smokers. -ProArgi9 Plus helps to accelerate wound healing and post surgery recovery. Research has shown it is useful in treating burn wounds and stimulates wound healing in the elderly. -ProArgi9 Plus may be useful in enhancing athletic performance due to its ability to boost exercise tolerance, its beneficial effect on the lungs, and its effect on HGH levels. Which helps with building lean muscle tissue.

How to Recognize a mitral regurgitation medication|Leaking Heart Valve
 
05:04
How to Recognize a mitral regurgitation medication|Leaking Heart Valve Disclaimer:This Video only For Educational Purpose The heart valves enable your blood to pass between the different chambers of your heart. When they leak it is called regurgitation. This happens when blood flows back into the chamber it came from as the valve is closing or if the valve does not close completely. This can occur in any of the heart valves. Because leaks make the heart less efficient at pumping blood, they force the heart to work harder to pump the same amount of blood. Treatment may include medications or surgery, depending on the cause of the leak and its severity 1 Reduce your salt intake. A low-salt diet can help lower your blood pressure, which will in turn reduce the strain on your heart. It will not repair a defective valve, but it can reduce the likelihood that it will get worse. Even if surgery isn’t necessary for you, your doctor may still recommend you eat a low-salt diet.[10][11] Depending on how high your blood pressure is, your doctor may want you to reduce your salt intake to 2,300 or even 1,500 mg per day. Some people eat as much as 3,500 mg per day. You can reduce your salt intake by avoiding salted processed foods and canned foods with salt added. Avoid adding table salt to your food, salting meat when you cook it, or salting rice and pasta water. 2 Lower your heart attack risk with medications. Which medications your doctor recommends will depend on your particular situation and medical history. If you are at a high risk of having blood clots or high blood pressure, your doctor will probably prescribe medications for those conditions. Medications will not repair a leaky valve, but they can improve conditions that make the leakage worse, like high blood pressure. Possible medications include:[12] Angiotensin-converting enzyme (ACE) inhibitors. These are common blood pressure medications for mild mitral regurgitation.[13] Anticoagulants such as aspirin, warfarin (Coumadin, Jantoven) and clopidogrel (Plavix). Blood clots can cause strokes and heart attacks. These medications reduce the probability that you will develop a blood clot. Diuretics. These medications prevent you from retaining too much water. If poor circulation is causing your legs, ankles and feet to swell, you may be prescribed diuretics. They will also reduce your blood pressure. Diuretics can be used to relieve swelling caused by a tricuspid regurgitation.[14] Statins. These medications lower cholesterol. High cholesterol is often associated with high blood pressure and it may exacerbate the leakage. Beta blockers. Beta blockers reduce the rate and force at which your heart beats. This reduces your blood pressure and can reduce the strain on your heart. 3 Repair a leaking valve. The standard way to repair a faulty valve is through surgery. If you have a valve repaired, be sure to go to a cardiac surgeon who specializes in valve repair. This will give you the best chances for a successful surgery. Valves can be repaired through:[15][16] Annuloplasty. If you have structural problems with the tissue around the valve, it can be reinforced by implanting a ring around the valve. Surgery on the valve itself or the supporting tissues. If the valve itself has been damaged through infection or injury, it may be necessary to repair the valve itself to stop the leak. Transcatheter Aortic Valve Replacement (TAVR). This is a newer, minimally invasive option for people who are unable to undergo open chest surgery.
