Atrial fibrillation is a common form of tachycardia. It occurs when the electrical activity of the atria occurs in a very disorganized and rapid pattern. The electrical activity stimulates the atria at random and at a high rate, causing the atria to contract very quickly, preventing the atria from functioning effectively. Although not usually life-threatening, the rapid, irregular, and disordered beating of the ventricles can cause dizziness or palpitations. If atrial fibrillation persists for several days, it may increase the risk of stroke. This is because the blood trapped in the atria can cause clots to form, which can travel from the heart to the brain and then cause a stroke.
