What is atrial fibrillation?

Arrhythmias. Atrial fibrillation (afib) is the most common sustained rhythm abnormality. It's characterized by an irregular heart rate. The upper chambers of the heart (atrium) do not beat but quiver. Many people don't notice it. But many do. It can lead to strokes in some patients so blood thinners are important. It can be treated with medications, ablation thru iv's in the groin or surgery. See a cardiologis.
