A treatment of choice because it may eliminate or cure a patient’s SVT. The physician inserts a catheter percutaneously. The catheter has an electrode at its tip, which is inserted into the area of heart muscle where there's an accessory pathway causing the extra electrical stimulation or impulse and subsequently the rapid heart rate. Then mild, painless radiofrequency energy (similar to microwave heat) is transmitted to the pathway, destroying the select problematic heart muscle cells. That stops the area from conducting the extra impulses that caused the rapid heartbeats.
