What is AFib?

Atrial fibrillation, or AFib, is the most common type of irregular heartbeat. It occurs when one or both of the upper chambers of the heart – called the atria – don’t beat the way they should. This can cause blood to pool in the left atrium, where a blood clot can form. If that clot breaks away, it can travel to the brain, where it can cause a type of stroke called an ischemic (is-KEE-mic) stroke.

AFib affects more than 2 million people in the United States. The odds of developing AFib go up with age. In fact, the American Heart Association states that AFib is the most common type of irregular heartbeat in people over the age of 65.
