Atrial fibrillation (AF) is an abnormal heart rhythm defined by an irregular, disorganized heartbeat. The top chambers of the heart quiver (fibrillate), and the fibrillating electrical activity is transmitted to the lower chambers of the heart where it results in irregular, often fast heart beats.

Medical and surgical treatments exist today to restore a normal heart rhythm, relieve symptoms and improve patients’ quality of life. The choice of treatment for AF depends on the severity of a person’s symptoms, prior treatments that were unsuccessful and other medical conditions that affect risk.

Our multidisciplinary team of cardiologists, surgeons and clinical nurse specialists successfully treats people with AF in order to slow down the heart rate and reduce symptoms. They also are active in leading clinical research on AF to develop and refine new treatments.
