What means antiarrhythmic?
Medical Definition of antiarrhythmic (Entry 2 of 2) : an agent (as a beta-blocker or calcium channel blocker) that controls, inhibits, or prevents cardiac arrhythmia.
Is digoxin a antiarrhythmics?
Class 5 antiarrhythmic drugs are a miscellaneous group of medications that do not belong to a traditional class of antiarrhythmics. These drugs have varied mechanisms of action and uses. The medications in this class are digoxin.
What drug stops your heart for 6 seconds?
bolus, the drug’s primary action is to slow electrical impulse conduction through the AV node. Be aware that adenosine commonly causes a few seconds of asystole, but because of its short half-life (6 to 10 seconds), the asystole usually is brief.
How do you memorize antiarrhythmic drugs?
Class I Antiarrhythmics are the sodium channel blockers, and these are further classified as Class IA, IB, and IC. To remember these, try Double Quarter Pounder, Lettuce Mayo, Fries Please.
Is propranolol an antiarrhythmic?
In summary, an antiarrhythmic response to propranolol occurs most frequently at a beta-blocking concentration. High concentration electrophysiologic effects occur and these appear to contribute to antiarrhythmic efficacy in some patients.
What drugs restart the heart?

What are the Class 3 antiarrhythmics?
Amiodarone, sotalol, dofetilide, and ibutilide are examples of class III drugs that are currently available. Amiodarone and sotalol have other antiarrhythmic properties in addition to pure class III action, which differentiates them from the others.
What is an example of an antiarrhythmic drug?
Examples of Class I Antiarrhythmics Common examples of sodium channel blockers include procainamide (class IA), lidocaine and phenytoin (class IB), and flecainide (class IC). Sodium channel blockers act on phase 0 of non-pacemaker cardiac myocyte action potentials by blocking the influx of sodium ions into the cell.

How do antiarrhythmic drugs work?
Antiarrhythmic drugs are used to treat abnormal cardiac rhythms such as atrial fibrillation, atrial flutter, ventricular tachycardia, ventricular fibrillation, etc. There are several different classes of antiarrhythmic medications and they act on different phases of cardiac myocyte and/or pacemaker cell action potentials.
Do class III antiarrhythmics block potassium channels?
As the name suggests, class III antiarrhythmics will block potassium channels. What part of the action potential did we say potassium was involved? We said it was involved in the “plummet” phase (phase 3) of both atrial/ventricular myocyte and pacemaker cell action potentials, in which the efflux of potassium led to repolarization of the cell.
