Heart Arrhythmia Atrial Fibrillation
An arrhythmia is a heart rhythm abnormality that may indicate a serious problem and can lead to heart disease, stroke or even death. An arrhythmia may be suspected when a physician hears a fast or irregular heartbeat while listening to the heart with a stethoscope.
Atrial fibrillation, or "AFib," is the most common type of arrhythmia - it affects about 2.2 million Americans, with 160,000 new cases diagnosed annually.
