Atrial Fibrillation Ablation
Atrial fibrillation (AF or A-fib) is the most common cardiac arrhythmia (irregular heart beat). It may cause no symptoms, but it is often associated with palpitations, fainting, chest pain, or congestive heart failure. It may be identified clinically when taking a pulse, and the presence of Atrial Fibrillation can be confirmed with an electrocardiogram (ECG or EKG) which demonstrates the absence of P waves together with an irregular ventricular rate.
During this procedure, a thin wire (catheter) is positioned inside your heart near the pulmonary veins. Radio energy applied to the tip of this catheter is used to cauterize (ablate) the heart tissue around each pulmonary vein. This electrically “disconnects” the pulmonary vein from the left atrium. As a result, the abnormal electrical signals from the pulmonary vein can no longer reach the rest of the heart and trigger atrial fibrillation.
