Premature Atrial Contractions are a Risk Factor for Heart failure
Atrial fibrillation (AF) is one of the most common abnormal or irregular heart rhythms (arrhythmias) in the world today. In AF, the atria (upper heart chambers) contract in a chaotic way causing the blood to pump through the heart less efficiently. Since the atria do not contract properly, blood pools in these chambers and tends to form clots. These clots may dislodge, and if they develop in the left atrium, can result in the most common complication of AF; a stroke.
