Atrial fibrillation (AFib) is a type of arrhythmia, or abnormal heart rhythm. According to the American Heart Association, it affects about 2.7 million Americans. People with AFib have an irregular beating of the heartâs upper chambers, called the atria. The atria beat out of synch with the lower chambers, called the ventricles. When this happens, not all blood gets pumped out of the heart. This can cause the blood to pool within the atria. Clots can form when the blood pools.
