Procainamide is a medication used to manage and treat ventricular arrhythmias, supraventricular arrhythmias, atrial flutter/fibrillation, and Wolf-Parkinson-White syndrome. It is in the antiarrhythmic Agent Class 1A class of medications.
Procainamide’s sodium channel blocking properties result in an increased threshold for excitability, and decreased automaticity. As a consequence of its potassium channel blocking properties, it prolongs action potential in most cardiac cells. It has atropine like action which is significant and also blocks alpha-adrenergic receptors.
