during an ablation high-frequency electrical energy is delivered through a catheter to a small area of tissue inside the heart that causes the abnormal heart rhythm. this energy "disconnects" the pathway of the abnormal rhythm. ablation is used to treat most psvts atrial flutter atrial fibrillation and some atrial and ventricular tachycardias. ablation may be combined with other procedures to achieve optimal treatment.
