Atrial fibrillation (also referred to as AF or AFib) is a common condition in which the upper chambers of the heart, or atria, fibrillate. This means that they beat very fast and irregularly so the heart can’t pump blood effectively to the rest of the body.


Normal Heartbeat

A small pulse of electric current spreads quickly through the heart to make the muscle contract.


Atrial Fibrillation

In atrial fibrillation, the heart’s upper chambers quiver faster than the rest of the heart.

AFib is a serious medical condition that can increase the risk of stroke by five times1 and over time, could lead to heart failure.


AFib is a dangerous condition that can occur even without symptoms. Heart monitoring can detect if and when you experience AFib to help your doctor manage your treatment.
