Atrial fibrillation and atrial flutter often revert to normal rhythms without the need for cardioversion. Healthcare providers usually try to correct the heart rhythm with medication or recommend lifestyle changes before recommending cardioversion.
Lifestyle...
changes often recommended to treat abnormal heart rhythms include:
- quitting smoking
- avoiding activities that prompt the symptoms of abnormal heart rhythms
- limiting alcohol intake
- limiting or not using caffeine (Caffeine products may produce more symptoms in some people with abnormal heart rhythms.)
- avoiding medications containing stimulants, such as some cough and cold remedies (These medications contain ingredients that may cause abnormal heart rhythms. Read all medication labels and ask a doctor or pharmacist for specific recommendations.)
If cardioversion is not successful in restoring the normal heart rhythm, other treatments for abnormal heart rhythms include:
- permanent pacemakers
- implantable cardioverter-defibrillator
- ablation therapy
- heart surgery, including the Maze procedure and the pulmonary vein isolation procedure

Definition
Cardioversion refers to the process of restoring the heart's normal rhythm by applying a controlled electric shock to the exterior of the chest.
Description
Elective cardioversion is usually scheduled ahead of time. After arriving at the hospital, an intravenous (IV) catheter will be placed in the arm and oxygen will be given through a face mask. A short-acting general anesthetic will be administered through the vein. During the two or three minutes of anesthesia, the doctor will apply two paddles to the exterior of the chest and administer the electric shock. It may be necessary to give the shock two or three times to obtain normal rhythm.
