Atrial Fibrillation
What is it?
Atrial fibrillation (AF) is a condition in which the heart beats with an abnormal or irregular rhythm. When the heart beats rapidly and irregularly, serious problems can occur such as blood clotting. The abnormal rhythm can come and go (called paroxysmal atrial fibrillation), persist for longer than 7 days (persistent atrial fibrillation), or persist despite treatment (permanent atrial fibrillation).
