Anti-Arrhythmic Drugs are medicines that correct irregular heartbeats and slow down hearts that beat too fast.

Normally, the heart beats at a steady, even pace. The pace is controlled by electrical signals that begin in one part of the heart and quickly spread through the whole heart. If something goes wrong with this control system, the result may be an irregular heartbeat, or an Arrhythmia. Anti-arrhythmic drugs correct irregular heartbeats, restoring the normal rhythm. If the heart is beating too fast, these drugs will slow it down. By correcting these problems, Anti-arrhythmic Drugs help the heart work more efficiently.

Anti-arrhythmic Drugs are available only with a physician's prescription and are sold in capsule (regular and extended release), tablet (regular and extended-release), and injectable forms. Commonly used anti-arrhythmic drugs are Disopyramide, Procainamide and Quinidine.
