Catheter Ablation for Heart Rhythm Problems

Catheter ablation is a minimally invasive procedure used to treat heart rhythm problems, such as atrial fibrillation or Afib. During the procedure, your doctor will selectively destroy heart tissue that is firing off abnormal electrical impulses.

Thin, flexible wires called catheters are inserted into a vein, typically in the groin or neck, and threaded to the heart. Electrodes at the tip of the wires carry radio waves that create heat to destroy the selected heart tissue. Another option is to use a freezing cold application to destroy the heart tissue.

A local anesthetic is used at the site where the catheter is inserted. You usually stay awake during the procedure but may be sedated.
