Atrial Fibrillation (Afib)

What is Afib?

Atrial Fibrillation (Afib), is an irregular heartbeat, a rapid heartbeat, or a quivering of the upper chambers of the heart called the atria. Afib results from a malfunction in the heart’s electrical system. Afib slows down the flow of blood throughout the body and can lead to acute heart problems. Blood that remains in the atria can pool and create blood clots, which can cause a stroke.
