6Your Summary |
Cardioversion uses an external defibrillator to return your heart to a normal rhythm.
First you are given a medicine that will relax you and control pain. Then a doctor places patches either on your chest or on your chest and back. The patches send an electric current to your heart. This resets your heart rhythm. The rhythm is more likely to return to normal and stay there if you also take antiarrhythmic medicines before and after this treatment.
Taking antiarrhythmic medicines alone—without electrical cardioversion—is another way to get back your normal heart rhythm. You may get pills, or the medicine may be put into your arm through an IV. If an IV is used, it will be done in the hospital. These medicines may not work as well as cardioversion. And they can have serious side effects.
The success of electrical cardioversion depends on how long you have had atrial fibrillation and what is causing it.
After this treatment, about 9 out of 10 people get back into a normal heart rhythm right away.footnote 1 But for many people, atrial fibrillation returns. Normal rhythm may last less than a day or for weeks or months. It depends on your other health problems.
Staying in a normal rhythm is more likely when the cause of your rhythm problem is not another heart problem. But for most people, atrial fibrillation is caused by another heart problem and is very likely to return.
If your atrial fibrillation returns, you may be able to have cardioversion again. But you might not stay in a normal rhythm for very long. If atrial fibrillation comes back quickly (within a week or so), having cardioversion a third time, or more, is less likely to help you. Your doctor might recommend a different treatment, such as a rhythm-control medicine, to get your heart rhythm back to normal.
If you take antiarrhythmic medicines too, they can help you stay in a normal rhythm longer.
Having a stroke is the most serious risk. Cardioversion may dislodge a blood clot in your heart. This can cause a stroke.
Before the procedure, your doctor will check your risk of stroke. To lower the risk of stroke, you might take an anticoagulant (blood thinner) before and after the cardioversion.
Cardioversion also has other risks:
If you choose not to try cardioversion, you still will be at risk for problems from atrial fibrillation, such as:
If your symptoms don't bother you a lot, your doctor may have you take medicines to slow your heart rate.

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.
I am only 45 and I don't want to spend the rest of my life feeling tired, out of breath, and like I have butterflies in my chest. I've decided to try cardioversion one time, to see if it will fix my atrial fibrillation.
Raymond, age 45
I didn't even know I had atrial fibrillation until my doctor found it during a physical exam. I have a couple of friends who went through a lot to get back to a normal rhythm, and it just seemed like too much trouble and then it didn't even work. Since I am not having symptoms, I think I will just take the medicines to control my heart rate and prevent strokes and not worry about it.
Tom, age 61
Managing my heart failure has become more difficult since I developed atrial fibrillation. My doctor has encouraged me to try cardioversion, because she hopes it will help my heart work better and help me feel better.
Manny, age 78
I have other health conditions that I am managing well with medicines. I don't have any symptoms. So, taking another drug won't change my life.
Margarita, age 82
