Catheter ablation is a procedure that uses radiofrequency energy (similar to microwave heat) to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. Destroying this tissue helps restore your heart’s regular rhythm. The procedure is also called radiofrequency ablation.
Special cells in your heart create electrical signals that travel along pathways to the chambers of your heart. These signals make the heart’s upper and lower chambers beat in the proper sequence.
Abnormal cells may create disorganized electrical signals that cause irregular or rapid heartbeats called arrhythmias. When this happens, your heart may not pump blood effectively and you may feel faint, short of breath and weak. You may also feel your heart pounding.
