Cardioversion restores a normal heartbeat in patients with arrhythmias, heartbeats that are too fast or irregular. Doctors use one of two methods for restoring normal heartbeat: medication or electric shock, also called electrical cardioversion.
Atrial fibrillation occurs when the signals sent out by the atrium, responsible for sending electrical impulses, are irregular, causing the heartbeat to become too fast or to beat in an irregular pattern. Doctors may use cardioversion to treat this common cause of arrhythmias. The treatment may also help restore a normal heartbeat in emergency and life-threatening situations.
