... In AF, disorganized electrical signals cause the heart’s two upper chambers to contract very fast and irregularly, or fibrillate. During an episode, blood pools in the atria and isn’t pumped completely into the heart’s two lower chambers. As a result, the heart’s upper and lower chambers don’t work ...
