Electrical Cardioversion

Sometimes electrical shock is required to restore a normal heart rhythm in patients with atrial fibrillation (AFib).  During a cardioversion, your physician will deliver a brief electrical shock to your heart, causing all activity to pause, giving your heart a chance to “reset” and let your normal heart rhythm take over. You will have an IV in your arm and will be connected to a heart and blood pressure monitor.  You will receive sedation through the IV and most likely will not remember anything about the procedure. After the sedation wears off and you are more awake, you should be able to go home later that day. 

How do I prepare for the test?

You should not have anything to eat or drink after midnight the night before the procedure. You should bring all your medications with you and should have someone to drive you home. 

Will I be awake for the procedure? 

You will be given medication through your IV to help you relax. You may be drowsy but should be able to follow directions if needed, such as deep breathing.
