What is a Cardioversion?

Cardioversion is a medical procedure used to restore a normal heart rhythm for people who have certain types of abnormal heartbeats (arrhythmias). Cardioversion is most often done by sending a small electric shock to your heart through electrodes placed on your chest.

Why do I need a Cardioversion?

You have been advised by your Cardiologist that you need a cardioversion because you have been experiencing erratic heart beats. The Cardioversion may restore your heart to a normal rhythm.

Who will perform my Cardioversion?

Your Cardiologist will perform the Cardioversion. An anaesthetist and a nurse will also be present.

Will I feel anything during the Cardioversion?

You will be put to sleep with a light general anaesthetic for your Cardioversion. This will be performed by an anaesthetist.

How long will the Cardioversion take?

The procedure only takes a few minutes and you will not feel any pain or discomfort.

You will wake up and be monitored in the ward for 1 – 2 hours, until you feel able to go home.

Can I have a support person with me during my Cardioversion?

Yes. You will not be able to drive yourself home after the procedure, so please ensure you have transport arrangements.

What happens next?

You will see your Cardiologist two weeks after the Cardioversion, to check that your heart has remained in the normal heart rhythm (“normal sinus rhythm.”)

Can I stop taking my blood thinning medication (warfarin, pradaxa) straight after my Cardioversion?

You must continue with these medications until you have had a follow-up with the Cardiologist.
