Electrical Cardioversion

This procedure is usually done to treat atrial fibrillation and is sometimes done to treat certain types of tachycardia.  Electrical cardioversion gives the heart a brief electrical shock to convert an abnormal heart rhythm back to normal.  Before the test, electrodes are placed on your chest and an intravenous line is inserted for medications and a sedative. During cardioversion, two large patches are placed on the chest and back and a perfectly-timed electrical shock is sent between the patches to restore the normal heart rhythm.  You should not feel any pain and will be awakened after the procedure for monitoring up to several hours.

Preparing for the Test:

• Do not eat or drink anything for 8 hours prior to the test.
• You may take any medications prescribed by your doctor with small sips of water.
• Make arrangements for someone to drive you to and from SJC’s office.
• Bring a list of all medications you are currently taking.
• Before the test, you’ll be given a brief explanation of the test and you’ll be asked to sign a consent form.  Feel free to ask any questions about the procedure.
