Should I be screened for atrial fibrillation?

Ask the doctors

Q. Two of my friends were recently diagnosed with atrial fibrillation. Should I be screened for this condition?

A. Atrial fibrillation is a condition in which the heart beats in an abnormal rhythm, for either brief intervals or a more extended period. Some people with the condition experience symptoms such as dizziness, a racing heartbeat, or lightheadedness. But for many others, the condition is identified only when they have heart testing done as part of a physical examination.
