What is Cardioversion?: Also known as electrical cardioversion, Cardioversion is a procedure used to treat certain types of irregular heart rhythms by use of an electrical charge. The procedure is done under anesthesia or a very strong sedative and is therefore painless.
How do I prepare for Cardioversion?: Do not eat or drink for 12 hours before your procedure. If you were prescribed an anticoagulant, like Digoxin, make sure to take it as ordered by your physician.
What will happen during the test?: You will be asked to sign a consent form. You will need to put on a hospital gown, and remove jewelry, glasses, dentures, hearing aides and nail polish. Then, a nurse will place a very small catheter (an IV) in one of your veins. This IV is used to administer relaxation and pain medication. You will then be connected to a heart monitor and two large, sticky electrode pads will be placed on the skin of your chest and back. Hair in the area where the electrodes are to be placed will be shaved. The insulated wires are connected directly to a defibrillator. The defibrillator is the machine operated by your physician to deliver the appropriate amount of electrical charge needed to correct your heart rhythm. You will then be taken to the recovery area and have your heart rhythm and blood pressure monitored until you are fully awake. The skin in the area of the electrodes may appear red and feel irritated. An ointment can be used on the skin to help the skin feel more comfortable.
What are the risks from the test?: There is a 2% risk of forming a blood clot. If you are taking a prescribed anticoagulant medication, even this risk is reduced.
What do I need to do after the test is over?: Continue to take your medications as ordered by your physician and keep any follow-up appointments as planned.
How long before I find out the results of my test?: The physician will discuss the results with you right away in the recovery area.
