Electrical cardioversion often returns the heart to a normal rhythm. After giving you a sedative, a doctor places paddles or patches either on your chest or on your chest and back, depending on your doctor's preference.

The paddles or patches send a low-voltage electrical current to the heart. The electrical current stops the heart momentarily. When it resumes beating, the heart usually starts in a normal rhythm, demonstrated in the regular line tracings seen in the normal electrocardiogram (EKG, ECG).
