Atrial fibrillation (A. Fib) occurs when the upper chambers of the heart beat irregularly due tomalfunction of the heart’s electrical signals. The irregular electrical signals cause improper blood flow out of the heart which can increase the formation of blood clots. When blood clots travel to the brain, this can block the blood flow of the brain and cause ischemic stroke. People with A. Fib has more than 5 times the risk of stroke including ischemic stroke and hemorrhagic stroke . It also increases the risk for heart failure.Symptoms may include fatigue, rapid heartbeat, discomfort in chest, shortness of breath, while some patients may not have any symptoms.
