About Atrial Fibrillation
Also known as AF or "afib," atrial fibrillation is an abnormal heart rhythm that occurs in the upper chambers of the heart (the atria), producing heart palpitations, elevated heart rate, and potentially other serious health risks including fainting, chest pain, congestive heart failure, and stroke. It is estimated that 4 million adults in the United States have some form of atrial fibrillation, with 160,000 new cases being diagnosed each year.
