A physician guides a catheter, with an electrode at its tip, to the area of heart muscle where the damaged site is located. Then, a mild, painless radiofrequency energy (similar to microwave heat) is transmitted to the site of the pathway. Heart muscle cells in a very small area (about 1/5 of an inch) die and stop conducting the extra impulses that caused the rapid heartbeats.
