How you prepare

Your doctor will evaluate you and may order several tests to evaluate your heart condition. Your doctor will discuss with you the risks and benefits of cardiac ablation.

You'll need to stop eating and drinking the night before your procedure. If you take any medications, ask your doctor if you should continue taking them before your procedure.

Your doctor will let you know if you need to follow any other special instructions before or after your procedure. In some cases, you'll be instructed to stop taking medications to treat a heart arrhythmia several days before your procedure.

If you have an implanted heart device, such as a pacemaker or implantable cardioverter-defibrillator, talk to your doctor to see if you need to take any special precautions.
