​Pre-Cardioversion Preparations

Your doctor will arrange a date for you to be admitted to the hospital. Usually you are admitted on the day of the procedure; occasionally, you will be admitted the day before.  

Most patients can expect to be discharged the following day; occasionally, your hospital stay may be longer if the procedure is difficult or complicated.

Do I continue to take my medications till the day of the procedure?

Your doctor should already have instructed you on what to do before the procedure. 

Please check with your doctor before discontinuing any medications. The following information is a general guide only.

Continue to take all of your medications as prescribed on the day of the procedure, unless you have been given other instructions.

If you need to take medications the morning of the procedure, please only drink small sips of water to swallow them. 

When you call for your procedure time, please ask the nurse for specific guidelines about taking warfarin on the day of the procedure.

If you have diabetes, ask the nurse how to adjust your diabetes medications or insulin before the procedure.

Can I eat before the procedure?

In most cases, you will be told to eat a normal meal the evening before your procedure. However, do not eat, drink or chew anything after 12 midnight before your procedure. This includes gum, mints, water, etc. If you must take medications, only take them with small sips of water. When brushing your teeth, do not swallow any water. 

What should I wear?

Wear comfortable clothes when you come to the hospital. You will change into a hospital gown for the procedure. Please leave all jewelry (including wedding rings), watches and valuables at home.

What happens before the procedure? 

Before the procedure begins, a nurse will help you get ready. You will be given a hospital gown to change into. You may keep your clothes in a locker or you may give them to a family member. 

You will lie on a bed and the nurse will start an IV (intravenous) line in a vein in your arm or hand. The IV is used to deliver medications and fluids during the procedure. 

EKG patches and adhesive cardioversion pads will be placed on your chest and sometimes on your back. Men may have their chest hair shaved if necessary.

The nurse will connect you to several monitors that allow the doctors to check your heart rhythm and blood pressure during the procedure. You are continually monitored during the procedure.


During Cardioversion: What to Expect

Will I be awake during the procedure?

No. A medication will be given through your IV to make you fall asleep during the procedure.

How long does the procedure take? What should I expect?

While you are asleep, the doctor will use the cardioverter machine (defibrillator) to deliver specific amounts of energy to your heart through the cardioversion patches. The shock interrupts the abnormal electrical rhythm and restores a normal heart rhythm.

Although the procedure only takes a few seconds, several attempts may be needed to restore the normal heart rhythm.

Overall the procedure itself takes a few minutes. However, the preparation and recovery time for the procedure may take hours. You will be monitored in the CCU until you have recovered.
