Atrial Fibrillation Ablation

Advanced electrophysiology labs perform ablation—a minimally invasive procedure—to treat atrial fibrillation, the most common and one of the most difficult to treat heart rhythm disorders.

How does radiofrequency ablation work?

Your electrophysiologist will a place a catheter into your heart. Tiny sensors in the tip gather information about precise electrical activity in the heart and feed it into a computer to create color-coded maps of the heart’s electrical pathways. This helps your doctor pinpoint the abnormal tissue causing the heart to beat too rapidly or at irregular intervals. Your electrophysiologist then places another catheter to deliver radiofrequency energy to the abnormal tissue. This modifies abnormal electrical pathways and restores the heart’s normal rhythm.
