Atrial Fibrillation: Disorganized Depolarization

Effect of Ablation: Organized Conduction

Huge Problem
According to the American Heart Association, approximately 5 million people in the United States suffer from AF and more than 350,000 new cases are diagnosed each year. The condition carries serious consequences. AF increases the risk of stroke fivefold, and is a major contributor to the development of congestive heart failure as well as more serious, life-threatening arrhythmias.

AF is an irregular heart rhythm that interferes with the heart’s ability to pump blood. Abnormal electrical signals begin at the top of the heart and travel down the muscle, causing the atria, or upper chambers, to contract erratically. As a result, blood pools in the atria and forms clots that can travel to the brain and cause stroke. AF is the most common form of arrhythmia, an irregularity in the normal rhythm of the heartbeat.
