Cardioversion is a procedure to restore the heart’s normal rhythm. This is done by administering a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle. During the procedure, you will be given medication through an IV to keep you free from pain. While your heart and blood pressure are monitored, a special machine is used to send electrical energy to the heart muscle. The procedure restores the normal heart rate and rhythm, allowing the heart to pump more effectively. The procedure is done on an outpatient basis in the hospital. An IV line will be started and medication will be administered by the RN. Electrodes will be placed on your chest to monitor your heartbeat throughout the procedure. Two electrode pads, each comprising a metallic plate which is faced with a saline based conductive gel, are placed on the chest and back and a very brief electric shock will be given through the pads. Your heartbeat will be watched to make sure it is restored to its normal rhythm. You will be monitored until you are fully awake and, in most cases, will be able to go home within a few hours after the sedation wears off. Take it easy the day after your procedure and call your doctor if you notice any chest tightness, skipped beats or rapid heartbeat.
