Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. ANTI-Arrhythmic agents are drugs used to SUPPRESS abnormal rhythms of the heart. They act to either: - interfere with the dynamics of cardiac action potentials by blocking a certain ion channel, or - block the sympathetic effects of the autonomic nervous system on the heart, to slow down heart rate. There are 5 classes of antiarrhythmic drugs: - Class I: Sodium-channel blockers: these drugs bind to and block the fast sodium channels that are responsible for the DE-polarizing phase in contractile myocytes. The result is a SLOWER depolarization with a smaller amplitude. This REDUCED conduction velocity helps to SUPPRESS formation of re-entrant circuits, hence the use of these drugs for treating re-entrant tachycardias. Class I agents are divided further into subclass IA, IB and IC. These subclasses differ in the STRENGTH of sodium channel blockage, and in their effect on the duration of action potentials and the effective refractory period, the ERP. While subclass IC has no effect on ERP, IA prolongs and IB shortens ERP, respectively. Changes in ERP may have different outcomes for different types of arrhythmias. A longer ERP generally reduces cardiac excitability, but prolonged repolarizations may increase the risk of torsades de pointes, a type of tachycardia caused by afterdepolarizations. - Class II: Beta-blockers: these drugs bind to beta1-adrenergic receptors and block the sympathetic influences that act through these receptors. Sympathetic nerves release catecholamines which act to increase SA node firing rate and cardiac conductibility, especially at the AV node. Useful in treatment of tachycardias that originate upstream of the AV node, known as supraventricular tachycardias, or SVT. - Class III: Potassium-channel blockers: these agents block the potassium channels responsible for the repolarizing phase. The result is a SLOWED repolarization, hence a PROLONGED duration of action potentials and refractory period. This reduces the heart’s excitability and suppresses re-entrant tachycardias. However, these drugs may also CAUSE arrhythmias because slow repolarizations are associated with LONGER QT intervals and INcreased risks of torsades de pointes. - Class IV: Calcium-channel blockers: these drugs block calcium channels that are responsible for DE-polarization in SA and AV nodal cells. Blocking these channels results in a LOWER sinus rate and SLOWER conduction through the AV node. However, because calcium is also involved in cardiac myocyte contraction, these agents also reduce contractility of the heart and should not be used in case of systolic heart failures. - Class V includes all drugs that act by other or unknown mechanisms.

Sotalol Sotalol is a drug used in individuals with rhythm disturbances of the heart cardiac arrhythmias It is a non-selective competitive beta-adrenergic receptor blocker that also exhibits Class III antiarrhythmic properties23 Originally discovered in 1960, sotalol became widely used first as a beta blocker in the 1980s, and its function as an antiarrhythmic drug was discovered soon after4 Due to the dual action of sotalol, it is often used preferentially to other beta blockers as treatment for both ventricular fibrillation and ventricular tachycardia25 Trade names for Sotalol include Betapace and Betapace AF Berlex Laboratories, Sotalex and Sotacor Bristol-Myers Squibb, and Sotylize Arbor Pharmaceuticals6 The US Food and Drug Administration advises that sotalol only be used for serious arrhythmias, because its prolongation of the QT interval carries a small risk of life-threatening torsade de pointes6 Contents 1 Medical uses 2 Mechanisms of action 21 Beta-blocker action 22 Type III antiarrhythmic action 3 Contraindications 4 Adverse effects 5 History 6 See also 7 Refe Sotalol Click for more; https://www.turkaramamotoru.com/en/sotalol-23914.html There are excerpts from wikipedia on this article and video

Treatment Options For Atrial Fibrillation – Patient information
 
02:01
Dr. Kneller discusses discuses treatment strategies for atrial fibrillation. Considerations include rhythm control (stopping and preventing atrial fibrillation) and rate control (slowing down the rapid heart rate caused by atrial fibrillation, without attempting to restore a normal rhythm), and whether systemic anticoagulation medication (ie, Xarelto, Eliquis, Pradaxa, or warfarin) is needed. Anti-arrhythmic medications (ie, flecainide, propafenone, sotalol, tikosyn) or catheter ablation are used to restore normal rhythm.

Atrial fibrillation: 2 key managment issues explained
 
03:28
In this video we try to explain two of the key issues for the management of atrial fibrillation. 1.The first issue is the issue of heart rate control versus heart rhythm control. Will your physician try to just control your heart rate or try to flip your rhythm back in to sinus rhythm from atrial fibrillation? With heart rate control our goal is to try to control the heart rate only. Thus the patient could still be in atrial fibrillation however heart rate is brought under control (60-110 bpm) with medications like beta blockers- metoprolol and calcium channel blockers like diltiazem etc. By rhythm control the physician tries to reset the heart into into sinus rhythm from atrial fibrillation. This can be done with the help of medications and is called as chemical cardioversion. Or it can be done by electrical shock also known as electrical cardioversion. Medications that can be used to keep the patient in the rhythm. These medications include, flecanide, sotalol or amiodarone etc. 2. The second key issue in the management of atrial fibrillation is prevention of stroke. Stroke is a deadly complication of atrial fibrillation. The first question that arises is what is the risk of stroke in a given patient with atrial fibrillation. A patients risk of stroke can be calculated by using an abbreviation called CHAD2VASC2 (explained in the table). Blood thinners (like Coumadin or newer agents like xeralto/apixaban/rivaroxaban) are recommended for patients with a score more than 2. For a score of zero usually no blood are recommended and for patients with the score of one either blood thinner or are aspirin as recommended.

In this video discussion, cardiologists Dr. Anne Curtis and Dr. Hiroko Beck discuss the risks and benefits of anticoagulant and antiplatelet medications for stroke and atrial fibrillation. The benefit of taking anticoagulant and antiplatelet medications is that they reduce the risk of stroke because they help to stop blood clots from forming. The main side-effect of these medicines is an increased risk of bleeding. The medications you take will depend on your risk of getting stroke, so speak to your doctor about balancing the benefits with the side effects of these medications. Take your medications as prescribed and have regular follow-up appointments with your doctor. Tell your doctor if your medicines are causing side effects.

Got Rhythm? An Update on the Treatment of Cardiac Arrhythmias
 
50:40
The heart normally has a steady beat. When the beat becomes irregular, takes off on its own, or misses a beat, a cardiac arrhythmia is present. While cardiac arrhythmias are usually benign, they can also be related to an increased risk of stroke and may be life-threatening. In this talk, Dr. Paul Wang, Director of the Stanford Cardiac Arrhythmia Service and Professor of Medicine and Bioengineering (by courtesy), talks about cardiac arrhythmias and new treatments.

Antiarrhythmic Drug Classes
 
35:17
Learning the Anti-Arrhythmic Agents just got a whole lot easier! ***MedImmersion to the rescue*** Listen guys, I really hope this video helps you in school. I definitely had fun making it! If you have questions, comments, or even criticisms...please, leave a comment. I love teaching and working with students, so your comments mean a lot to me! Good Luck in school! Hey YouTube, this is Dr. Joel. In this video, I'm gonna be covering the antiarrhythmic agents. I'm gonna start with a review of cardiac physiology, and then jump right into the agents themselves. I'll cover the Class I, Class II, Class III, Class IV, Class V, and then just give you some departing thoughts and then I will finish off with a couple of knowledge challenge questions, just to see where you're at. OK? Let's get started. In order to do a really good review of the cardiac antiarrhythmic agents, it's first important important for me to cover a little bit of cardiac physiology, starting first with the cardiac action potential. And that's because this action potential is a little bit different than the action potential that you're going to see in nerves. Also, a solid understanding of this action potential will help you later understand why the drugs work the way they do. So, this picture on the right represents a cardiac action potential. And, one thing that you need to understand is that this action potential is going to be a little bit different depending on which part of the heart you're measuring. However, the principles that I'm about to cover will apply to all of those tissues in the heart. And, if you want to, you can click on this link, which will take you to a picture that I think does a really cool job about showing the differences in the cardiac action potential in the different sections of the heart and that also how all those electrical depolarizations add up to make the electrocardiogram wave form. Anyway, on the X axis, we have time and on the Y axis, we have voltage. In the polarized state, the heart rests at about negative 95 millivolts. An action potential cycle takes about 200 milliseconds. And that number changes depending on which part of the heart you're in or which tissue you're sampling. So, on this graph, you can see that the heart starts at about negative 95 millivolts then it very quickly shoots up to about 20 or so, by this graph, pause at 20 millivolts. It stays there for a bit, and then the cell starts to repolarize itself. And that's the cycle. I'm going to add a cell membrane at the top of this picture and I'm going to walk through the phases of the action potential one at a time and what I want you to do is, I want you to imagine that above this cell membrane is the extracellular space and below this membrane is the intracellular space. OK, starting off with Phase 0, which is the depolarization phase. This is caused by a opening of voltage-gated sodium channels. And these are very fast, rapid-acting channels that allow a large amount of sodium to move very quickly. Sodium is positively charged, so if positive things come into the cell, then the cell becomes more positive. OK, does that make sense? Basically, that's why you see this huge skyrocketing here of the voltage from negative 95 to positive 20. It's because those positive sodium ions are moving in very quickly. Next is Phase 1, which is the initial repolarization phase, which is basically caused by the rapid inactivation of those sodium channels. Almost as quickly as they open, they start to close again. At the same time, voltage-gated potassium channels start to open allowing potassium to efflux or exit the cell. Potassium is also positively charged. So if you have positive things leaving the cell, then the cell becomes more negative, right? And that's why there's a little dip there in the voltage. Next, with Phase 2, you get calcium channels and they begin to open. Calcium, again, also positive. Positive things coming into the cell would make the cell more positive. But potassium is still moving out, so that would make the cell more negative, and hence you get this plateau phase. It kind of balances out for a little bit. It's not exactly flat, but it's close. We still call it the plateau phase. And, as you know, the calcium plays an effect on how the muscle cells contract. So that's important as well for contraction. Next is the rapid repolarization phase, which is Phase 3. More of the voltage-gated slow potassium channels are opening and they allow more potassium to rush out and the calcium channels begin to close so the cell starts to move back down to a negative value, a strong negative value. And you have to remember, the sodium-potassium ATPase pump is also chugging along this whole time. It's still working, it's still pumping potassium in and sodium out, which is just another factor that is driving that cell back down to its polarized state. Lastly is the fourth phase, which is the resting potential phase.

Potassium channel blockers
 
13:13
Potassium Channel Blockers are easy! Check it out! I work hard to make and find the best videos for you to study from (it’s not easy)! You can help by suggesting any good videos you've seen in the comments below! Good luck in school!! Hey, guys. This is Dr. Joel with MedImmersion. You are watching a flash flood review series video where I review the highest yield stuff for your board exams in as little time as possible. In this video, I'm going to be talking about the potassium channel blockers, which are a class of the antiarrhythmic agents. I'll cover some general principles about the class as a whole, and then a few specific drugs in that category, or in this class. It's gonna be awesome, so stick around. If you watch a lot of MedImmersion videos, and they're helpful for you, think about getting an account at medimmersion.com. That will speed you up in your studying because when you're logged into MedImmersion on your browser and use the links in these videos, you will automatically skip past these lengthy introductions on my MedImmersion videos and also on other people's videos that I've linked to. And you'll be able to skip over a lot of the YouTube advertisements on my MedImmersion videos. Okay. Let's jump into it. This lecture is going to cover a subset of the antiarrhythmics, the potassium channel blockers. I'll give you an introduction as to what they are. Then, talk about some general principles that will include the mechanism of action, clinical uses, adverse or side effects, and then I will cover a couple of the highest yield examples in this class. Alright. First of all, if you need to review the entire topic of the antiarrhythmics, with a little bit of cardiac physiology, you should really go over and watch The Antiarrhythmic Agents Lecture first. This lecture, right now, is a little bit more focused, and I assume that you know a couple of things about antiarrhythmics. So, the potassium channel blockers, in the Vaughn Williams Antiarrhythmic Agent Classification, are the Class III antiarrhythmics. You should know that. And we use the potassium channel blockers and the Class I, or sodium channel blockers, for rhythm control. The Class IIs and Class IVs are more rate control. Four drugs that we're gonna talk about amiodarone, ibutilide, dofetilide, and sotalol, which you can remember by the mnemonic AIDS. As for the mechanism of action, these block myocardial potassium channels, and that has its primary effect on the specific potassium channels that are responsible for the delayed rectifier current, which have a very important contribution on the length of the action potential, and thus, the effective refractory period of cardiac myocytes. And to explain that a little bit further. Have you ever wondered why exactly the action potential of a neuron through the spinal cord or a peripheral neuron looks different than the action potential in myocardium. Well, it's built that way on purpose. The plateau phase, or the prolongation of the action potential, or the refractory period, gives cardiac tissue special properties that prevent it or contribute to prevention of arrhythmias. So, the picture on the left is what maybe a bland neuron action potential might look like in the peripheral nervous system. On the right, we have a cardiac action potential. And both of these are pretty bland images. They're not exactly right. But the point here is that there's a plateau where the cell stays in its non-polarized state for a little bit longer, for a period of time. Potassium plays a big part in that. The initial depolarization is caused by a rapid influx of sodium. And then, it's maintained in that depolarized state by both calcium and potassium trading places across the cell membrane in relatively small amounts. In phase three, which is the repolarization phase, finally there's a delayed switch, or a delayed rectifier current of potassium, which finally turns on and allows an efflux of positive ions, allowing the membrane potential to come back down to a very negative number. So, hopefully you can see why if we mess around with the potassium channels that contribute to phase three, we prolong or at least change the shape of the cardiac action potential, which, of course, would have an effect on some kinds of arrhythmias. So, it was pretty easy to see, I think, from that previous picture that delaying the potassium efflux during the repolarization phases increases or stretches out the action potential duration and also the effective refractory period. Also, these do not have any effect on the sodium channels, meaning that the conduction velocity, or phase zero, wouldn't be affected or decreased. And visually, it looks like this, the action potential stretched out and the effective refractory period is increased. Also, that means that the QT interval is prolonged. Okay. Does that make sense? We use the Class III antiarrhythmic agents for rhythm control.

Take Dr. Berg's Advanced Evaluation Quiz: http://bit.ly/EvalQuiz Your report will then be sent via email analyzing 104 potential symptoms, giving you a much deeper insight into the cause-effect relationship of your body issues. It's free and very enlightening. Dr. Berg talks about the best tip for atrial fib. This is based on the book, Beat Your A-Fib by Steve Ryan Ph.D. This condition is usually triggered by a magnesium deficiency. It can also be a potassium deficiency. However it is difficult to determine these mineral differences because of where most of the minerals are located - inside the cell. It is recommended to take a type of magnesium called angstrom, which is 1 million times smaller than other forms.
