Atrial fibrillation (also called AFib or AF) is an irregular, weak heartbeat that increases the risk of heart disease and stroke. When your heartbeat isn't strong and steady, blood can collect or pool in the upper chambers of the heart. Clots can then form and travel to the brain, the legs and other areas. In the brain, clots can block blood flow and cause a stroke.
