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 may be instructed to stop taking certain medications several days before your procedure.
Cardiac ablation works by scarring or destroying tissue in your heart that triggers or sustains an abnormal heart rhythm. In some cases, cardiac ablation prevents abnormal electrical signals from entering your heart and, thus, stops the arrhythmia.
Cardiac ablation usually uses long, flexible tubes (catheters) inserted through a vein or artery in your groin and threaded to your heart to deliver energy in the form of heat or extreme cold to modify the tissues in your heart that cause an arrhythmia.
Following your procedure, you'll be moved to a recovery area to rest quietly for four to six hours to prevent bleeding at your catheter site. Your heartbeat and blood pressure will be monitored continuously to check for complications of the procedure.
Depending on your condition, you may be able to go home the same day as your procedure, or you may need to stay in the hospital. If you go home the same day, plan to have someone else drive you home after your procedure.
You may feel a little sore after your procedure, but the soreness shouldn't last more than a week. You'll usually be able to return to your normal activities within a few days after having cardiac ablation.
