Most elective (non-emergency) cardioversions are performed to treat atrial fibrillation or atrial flutter, which are heart rhythm disturbances originating in the upper chambers (atria) of the heart.

A cardioversion is a brief procedure where an electrical shock is delivered to the heart, converting an abnormal heart rhythm into a normal rhythm. For most people, cardioversion can quickly restore a regular heartbeat. However, you may need repeat procedures to keep a normal heart rhythm.

Cardioversion is different from defibrillation, an emergency procedure that's performed when your heart stops. Defibrillation delivers more powerful shocks to the heart to correct its rhythm.
