When medications aren’t able to restore your heart’s normal rhythm, your physician may recommend cardioversion to reset your heartbeat. Trust the electrophysiologists at the Bob and Patty Edwards Arrhythmia Center at Overlake for a safe, effective cardioversion procedure.

What Is Cardioversion?

During electrical cardioversion, your physician uses a low-energy shock—delivered through pads placed on your chest and back—to restore your heart’s normal rhythm. Before the procedure, you’ll take medicine that puts you into a deep sleep so you won’t feel any pain.

Will I Benefit from Cardioversion?

Your physician may recommend cardioversion if you experience symptoms from an arrhythmia such as:

Cardioversion also may be used in emergency situations.

How to Prepare for Cardioversion

Your health care provider will give you directions on how to prepare for your cardioversion. Be sure to follow his or her instructions about food, drink and medications. Don’t use lotions, powders or ointments on your chest or back for 24 hours before your procedure.

Ask a friend or family member to drive you to your appointment, remain in the hospital during your procedure, and drive you back home.

What to Expect After Cardioversion

Electrical cardioversion takes only a few minutes, but you’ll stay in the hospital for several hours after the procedure so your care team can monitor your health. You’ll probably return home the same day.

The skin on your chest may feel sore for a few days.

Electrical cardioversion corrects your heartbeat immediately, but it doesn’t prevent future episodes of arrhythmia. That means your physician will probably prescribe medications to prevent your arrhythmia from recurring. You may also need to take blood thinners to reduce your risk of stroke.

Call your provider if you experience chest pain, dizziness, fainting or heart palpitations after your procedure.
