Antiarrhythmic agents

What are Antiarrhythmic agents

Antiarrhythmic agents are pharmaceuticals used to combat cardiac arrhythmias. An arrhythmia is an abnormality of the rate or rhythm of the heartbeat, such as atrial fibrillation, atrial flutter, ventricular fibrillation and ventricular tachycardia. Anti-arrhythmia agents are often classed into five main groups according to their mechanism of action, using the Vaughan-Williams classification. Many of the agents however, listed in the five groups, have considerable overlap in their pharmacologic properties.
