What Is an Afib Attack

Atrial fibrillation (AFib) is the most common type of irregular heartbeat. The abnormal firing of electrical impulses causes the atria (the top chambers in the heart) to quiver (or fibrillate).

What triggers AFib attacks?

Typically, anything that makes you stressed or tired can bring on an attack. Stress and atrial fibrillation often go together. Common activities that can bring on an AFib episode include travel and strenuous exercise. Holidays are often a trigger as well, because they typically include two triggers: stress and alcohol.

How serious is an AFib attack?

AFib is a serious diagnosis. While this condition isn’t fatal in itself, it can lead to potentially life-threatening complications. Two of the most common complications of AFib are stroke and heart failure, both of which can be fatal if not managed quickly and effectively.
