Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.

Ibutilide is a Class III antiarrhythmic agent that is indicated for acute cardioconversion of atrial fibrillation and atrial flutter of a recent onset to sinus rhythm. It exerts its antiarrhythmic effect by induction of slow inward sodium current, which prolongs action potential and refractory period of myocardial cells. Because of its Class ...
This contrasts with (ordinary) use dependence, where the efficacy of the drug is increased after repeated use of the tissue. Reverse use dependence is relevant for potassium channel blockers used as class III antiarrhythmics. Reverse use dependent drugs that slow heart rate (such as quinidine) can be less effective at high heart rates. [11]
Flecainide is a medication used to prevent and treat abnormally fast heart rates. [1] This includes ventricular and supraventricular tachycardias. [1] Its use is only recommended in those with dangerous arrhythmias or when significant symptoms cannot be managed with other treatments. [1]
Disopyramide (INN, trade names Norpace and Rythmodan) is an antiarrhythmic medication used in the treatment of ventricular tachycardia. [2] It is a sodium channel blocker and is classified as a Class 1a anti-arrhythmic agent. [3] [4] Disopyramide has a negative inotropic effect on the ventricular myocardium, significantly decreasing the ...
Anti-clotting medications include warfarin and direct oral anticoagulants. [25] While these medications reduce stroke risk, they increase rates of major bleeding. [27] Atrial fibrillation is the most common serious abnormal heart rhythm and, as of 2020, affects more than 33 million people worldwide.
