Cardioversion

Preparation
Electrical cardioversion is the technique of applying a light shock to the chest to correct certain arrhythmias. Typically, atrial fibrillation and atrial flutter are the most common arrhythmias that are treated this way. Dr. Moore only uses this option when medication is not adequate to keep the patient feeling well. This electronic shock to the heart, which can be administered internally or externally, restarts the heart or helps the heart to resume its normal rhythm.

Dr. Moore performs cardioversions at Indian River Memorial Hospital. To prepare for this procedure, you must:

  • Inform Dr. Moore if you may be pregnant
  • Abstain from eating or drinking at least six to eight hours prior to the test
You may have to stop taking certain medications, such as digoxin, prior to this procedure and obtain pre-procedure blood work. You also may have to pre-register for this outpatient procedure. Dr. Moore and his staff will provide you with specific instructions.

Note: Because you'll be sedated during this procedure, you'll be unable to drive afterwards. You must bring someone with you to drive you home and keep an eye on you.

Procedure
Once you have registered, changed into a hospital gown, and been situated in bed, you'll receive an intravenous (IV) line that will be used to administer a sedative that will put you to sleep for the procedure. Electrodes will be attached to your chest to monitor your heart, and a cuff will be placed on your arm to monitor your blood pressure. You'll also be connected to equipment that will help you breath. The cardiologist will then use external heart paddles to shock your heart and convert it to a normal rhythm.

You'll be monitored for a short time after the procedure before you're released from the hospital to someone who can drive you home.

Post-procedure
After the procedure, a follow-up appointment with Dr. Moore will be scheduled. You may also have to obtain follow-up testing to see if your heart is able to maintain the normal rhythm. Resume your normal medication schedule as instructed by Dr. Moore.
