Why is Atrial Fibrillation Concerning?

Because atrial fibrillation is a chaotic rhythm disorder of the atria, the upper chambers of the heart do not contract forcefully or effectively.

As a result, blood is not pumped efficiently from the atria into the ventricles. When this happens, blood can become stagnant within the atrial chambers.

Stagnant blood increases the risk of blood clot formation. If a clot travels from the heart to the brain, it can cause an embolic stroke.
