The procedure will be done in the hospital, in the electrophysiology (EP) laboratory. You’ll be awake during the procedure but you’ll be given a sedative to help you relax. Your heart and blood pressure will be monitored the entire time.
While you lay flat on a table in the EP lab, your cardiologist will insert a needle into a vein in your groin (or possibly your arm or neck), after first numbing the area. Then slender tubes called catheters will be threaded through your veins into your heart. The catheters have special electrodes on their tips that can detect abnormal electrical impulses in your heart and send out pulses of radiofrequency energy to destroy problem tissue and leave scar tissue in its place.
The radiofrequency ablation procedure takes several hours, depending on how many areas of the heart are generating abnormal electrical impulses. Your cardiologist will carefully create lines of scar tissue around each of them. You may feel some discomfort when the catheter is sending out radiofrequency energy. Be sure to let your doctor know if you feel severe pain or shortness of breath.

The first inkling that you have PAD is often a painful cramp in the calf or thigh that occurs repeatedly when you walk, but disappears when you’re at rest. This symptom is known as intermittent claudication. People with PAD often curtail their activity to avoid further pain. However, inactivity only worsens the condition, creating a downward spiral.
As PAD becomes more advanced, other symptoms may develop including:
