Normally, the heart has a strong, steady beat. That beat is controlled by the heart's electrical system. Sometimes the system misfires, causing an irregular heart rhythm (arrhythmia). In atrial fibrillation, the heart's upper chambers quiver (fibrillate). The lower chambers beat without a regular rhythm and may beat too fast. This may cause symptoms, such as feeling dizzy, tired, or short of breath. It also can make you more likely to have a stroke.
Electrical cardioversion is one treatment option to try to stop atrial fibrillation and keep it from returning. It can also relieve symptoms of atrial fibrillation.
First, you'll get medicine through a vein to block pain and make you sleepy (I.V. sedation). Then a doctor will put patches on your chest or on your chest and back. After you are sedated enough, the patches deliver a brief electric shock to your heart. This resets your heart rhythm.
You may take rhythm-control medicines (antiarrhythmics) before and after cardioversion. This can make it more likely that your heart rhythm will return to normal and stay there. You will likely take a blood-thinner medicine (anticoagulant) to prevent blood clots before and after the procedure. This medicine lowers your risk of a stroke.
For most people, cardioversion restores a normal heart rhythm right away. But atrial fibrillation often comes back. Normal rhythm may last less than a day or for weeks or months. How long it lasts depends on a few things. These include how long you've had atrial fibrillation, what's causing it, and whether you have another heart problem. Taking antiarrhythmic medicines can help you stay in a normal rhythm longer.
Your doctor can help you understand how well cardioversion might work for you.
If your atrial fibrillation returns, talk with your doctor about your next treatment options. You may choose to have cardioversion again. Or your doctor might recommend a different treatment, such as catheter ablation or medicines to control your heart rate or rhythm.
No matter what treatment you choose, it's important to take steps to prevent a stroke, manage other health problems, and have a heart-healthy lifestyle.
Cardioversion does have some risks. For example:
Your doctor can help you weigh your personal risks against the possible benefits of cardioversion.

I was just diagnosed with atrial fibrillation. I decided to have cardioversion to see if it stops the unhealthy rhythm for a while.
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
I had a cardioversion a long time ago, and it worked for a good while. I don't like the symptoms I'm having now, so I'm going to try cardioversion again.
Margarita, age 82
