What is atrial fibrillation?
Atrial fibrillation is an abnormal heart rhythm that causes a fast and irregular pulse. In atrial fibrillation, parts of the atria send disorganized electrical impulses into the top of the heart. These abnormal discharges cause the atria to shake like jelly. This activity takes over the heart’s normal beats, and the body is not able to control how fast the heart is beating. This causes the most common symptom of atrial fibrillation: fatigue.

Atrial fibrillation is the most common type of abnormal heart rhythm. An estimated three to six million Americans have it. In fact, it happens so commonly, doctors have a nickname for it — “a fib.” Most often, the risk of a fib increases as we get older. As people age, so does their heart, and age is the biggest risk factor for developing a fib. Just 2% of people under the age of 65 have atrial fibrillation, but as high as 9% of those over the age of 65 have it.
