(Also known as Catheter Ablation)
What the Procedure Does
A catheter with an electrode at its tip is guided through the veins to the heart muscle with real-time, moving X-rays (fluoroscopy) displayed on a video screen. The catheter is placed at the exact site inside the heart where cells give off the electrical signals that stimulate the abnormal heart rhythm. Then a mild, painless radiofrequency energy (similar to microwave heat) is transmitted to the pathway. This destroys carefully selected heart muscle cells in a very small area (about 1/5 of an inch).
Reason for the Procedure
- Preferred treatment for many types of rapid heartbeats (arrhythmias) especially supraventricular tachyarrhythmias.
