Your options
- Have electrical cardioversion.
- Don't have cardioversion. Try other treatments to restore a normal heart rhythm and relieve symptoms.
Key points to remember
- Cardioversion can return your heart to a normal rhythm. This helps relieve symptoms of atrial fibrillation.
- For most people, cardioversion restores a normal heart rhythm right away. But atrial fibrillation often comes back. Many factors affect how long the heart stays in a normal rhythm. Your doctor can help you understand how well cardioversion might work for you.
- Cardioversion is just one way to treat atrial fibrillation.
- If atrial fibrillation returns after this procedure, you may try cardioversion again or you can choose another treatment.
- Cardioversion does have some risks. These range from minor burns from the patches to a stroke or a dangerous abnormal heartbeat. Your doctor can help you weigh your personal risks against the possible benefits of cardioversion.
- 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.
What is electrical cardioversion?
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.
How well does cardioversion work?
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.
What are the risks of cardioversion?
Cardioversion does have some risks. For example:
- You may have minor burns on the skin where the patches were placed.
- Some people have a reaction to the sedation medicine given before the procedure.
- Antiarrhythmic medicines used before and after this treatment may cause a dangerous irregular heartbeat. The cardioversion itself may also cause this.
- Cardioversion might dislodge a blood clot in your heart. This could cause a stroke. Taking a blood thinner before and after the cardioversion can lower the risk of a stroke.
Your doctor can help you weigh your personal risks against the possible benefits of cardioversion.

- Cardioversion is done in a hospital. You'll get medicine to make you sleepy. You will not feel any pain.
- Cardioversion itself takes about 5 minutes. But the whole procedure, including recovery, may take a few hours.
- You may take rhythm-control medicines and a blood-thinner medicine before and after cardioversion.
- Cardioversion restores normal heart rhythm for most people. This can relieve symptoms of atrial fibrillation.
- Redness that looks and feels like a sunburn where the patches were placed.
- Reaction to the sedation medicine.
- Dangerous irregular heartbeat.
- Stroke.
- You may decide to try other treatments to relieve symptoms, such as catheter ablation or medicines to control your heart rate or rhythm.
- These treatments may help relieve symptoms.
- They depend on the treatment you choose. Catheter ablation has some risks, including bleeding and bruising. Medicines may cause side effects, such as feeling tired or dizzy. Your doctor can explain the risks and side effects of these treatments.
Personal stories about cardioversion
These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.
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
