About Antiarrhythmic - Class III.

Class III antiarrhythmics are a functional category of cardiovascular medications defined under the Vaughan Williams classification system.

These agents work predominantly by blocking cardiac potassium channels, which delays phase 3 repolarization and lengthens both the myocardial action potential duration and the effective refractory period without significantly slowing conduction velocity.

Clinically, they are utilized to terminate and prevent various tachyarrhythmias, most notably atrial fibrillation, atrial flutter, and life-threatening ventricular arrhythmias such as ventricular tachycardia and ventricular fibrillation.

Commonly used agents within this therapeutic class include amiodarone, sotalol, dofetilide, and ibutilide.
