What happens when the heart goes into fibrillation?

Life with atrial fibrillation has its challenges, for sure. But with the right treatment and some lifestyle changes, you can stay active and energetic . Symptoms such as fatigue, shortness of breath, and a fast heartbeat can make it harder to get around and do your daily activities.

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.

During atrial fibrillation, the heart’s upper chambers (the atria) beat chaotically and irregularly — out of sync with the lower chambers (the ventricles) of the heart . For many people, A-fib may have no symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness.19 Eki 2021
