Elective cardioversion is a planned medical procedure that uses a controlled electric shock to restore a normal heart rhythm in people who have an irregular heartbeat, such as atrial fibrillation. It is done in a hospital setting, usually under sedation, to help the heart beat regularly again.
Key facts
Yes, elective cardioversion is a common procedure for people with atrial fibrillation or other heart rhythm problems.
It mainly affects adults, especially those over 60, and people with heart conditions such as high blood pressure, heart failure, or valve disease.
Your doctor will typically diagnose the irregular heart rhythm using an electrocardiogram (ECG), which records the electrical activity of your heart. You may also have other tests to check the structure of your heart and your risk of blood clots.
If your doctor recommends elective cardioversion, you will have a visit beforehand to discuss the procedure, medications, and any risks. On the day of the procedure, you will be given sedation, then a small electric shock is delivered through paddles or patches on your chest. It usually takes only a few seconds. You will be monitored for a few hours afterwards before going home.
The main treatment for restoring a normal rhythm is elective cardioversion. Before the procedure, most people are given blood-thinning medicine for several weeks to reduce the risk of stroke. The procedure itself is done in a controlled hospital setting with sedation. Afterward, you may continue blood thinners and possibly rhythm-control medication to help maintain a regular heartbeat.
Medical treatment before and after cardioversion often includes blood-thinning medications to prevent clots, and medications to control heart rate or help maintain a normal rhythm. Your doctor will choose the best medicines based on your health needs. In some cases, an injection of a medicine through a vein can also be used to try to convert the rhythm without electricity.
After elective cardioversion, most people feel better because their heart rhythm returns to normal. However, you may need to continue taking medications and have regular check-ups. If the irregular rhythm returns, you and your doctor can discuss repeating the procedure or other options.
A heart-healthy diet (rich in fruits, vegetables, whole grains, and lean protein) along with regular moderate exercise, such as walking, swimming, or cycling, can help maintain heart health. Always check with your doctor before starting a new exercise routine.
While you cannot always prevent the underlying heart condition, you can lower your risk by controlling high blood pressure, maintaining a healthy weight, limiting alcohol, and managing stress. If you already have an irregular rhythm, taking prescribed medications can help prevent recurrence.
There are no vaccines specifically to prevent arrhythmias. However, staying up-to-date with recommended vaccines (including flu and pneumonia) can help prevent infections that might worsen heart conditions.
Routine screening for irregular heartbeat is not typically done for everyone. Your doctor may check your pulse at regular check-ups. If you have risk factors or symptoms, an ECG may be recommended.
For most people, elective cardioversion is a safe and effective way to restore normal rhythm and improve symptoms. Even if the irregular rhythm returns, many people can have repeated procedures or explore other treatments. With proper medical care and lifestyle changes, the outlook is generally good.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
If cardioversion does not work or the irregular rhythm returns, your doctor may discuss other procedures such as catheter ablation (a procedure that destroys tiny areas of heart tissue causing the abnormal rhythm) or pacemaker implantation. These are considered when medicines and cardioversion are not effective.
Living with an irregular heartbeat can cause anxiety or worry about your health. It is normal to feel this way. Talking with your doctor or a counselor can help. Many people find relief once the rhythm is restored and they know what to do if symptoms return.
