Heart Disease and Abnormal Heart Rhythm (Arrhythmia)

(continued)

What Is Catheter Ablation?

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 for optimal treatment.

What Is Heart Surgery?

Heart surgery may be needed to correct heart disease that may be causing the arrhythmia. The Maze procedure is a type of surgery used to correct atrial fibrillation. During this procedure, a series (or "maze") of incisions are made in the right and left atria to confine the electrical impulses to defined pathways. Some people may require a pacemaker after this procedure.
