Atrial fibrillation is an irregular and rapid heart rate that can increase your risk of stroke, heart failure and other cardiac complications. When atrial fibrillation happens, the atria and the ventricles or the upper and the lower chambers of the heart would not be synchronized with one another. It could either come sometimes and repeat at intervals or not go at all.
By itself, atrial fibrillation may not be very dangerous. However, it is a complex situation of the heart that screams for attention, because it can lead to blood clots and blood blockages.
