Radiofrequency catheter ablation is done for people with life-threatening tachycardias. This is done with several catheters in the heart. One is positioned directly over the area that causes the tachycardia. The tip of the catheter is then heated and that small area of the heart is altered so that the electrical current won't pass through the tissue. Usually the Intracardia Electrophysiological Procedure is done before this one to locate the area that's causing the tachycardia. On some occasions instead of this procedure a surgery is done in place of it to interrupt the abnormal connection in the heart. These treatments may eliminate the tachycardia permanently. But it is usually not recommended unless the tachycardia becomes an extremely severe problem.
