Radiofrequency ablation is a minimally invasive procedure that will be performed at Dignity Health’s St. John's Regional Medical Center by one of our expert cardiologists. The procedure lasts about four hours. However, you should plan to spend all day at the hospital. You’ll be given anesthesia to make you sleep.
During the cardiology procedure, your doctor will insert a thin, flexible tube (catheter) into a large blood vessel in your groin, arm, or neck. The catheter will be fed toward your heart, allowing your doctor to assess the electrical activity in your heart and find the cells that are causing the irregular heart rhythm.
When the abnormal cells are located, a special catheter tip that generates heat energy will be applied to the cells. You may feel a slight burning sensation as the heat destroys these cells. This is normal, and you shouldn’t feel any pain.
