What is Atrial Fibrillation?
... The walls of the atria and ventricles are made of virtually 100% pure muscle. A heartbeat is caused by the tightening of these muscles. When the muscles tighten the chambers squeeze closed and push out the blood which is inside them. Heartbeat control begins with the sinoatrial node - a small clump ...
