Atrial fibrillation (AFib or AF) occurs when the upper chambers of the heart beat irregularly due to malfunction 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 AFib 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.

心房顫動 (AFib) 是指由於心臟電信號故障導致心臟上腔室不規則搏 動。當血凝塊移動到大腦時,會阻止大腦的血液流動,稱為 缺血性中風。有心房顫動的人患中風的風險(抱括缺血性中風出血性中風)高達5倍以上,並增加心力衰竭風險 (圖 2) 。 有些患者的症状可能會出現疲勞 ,心跳加速,胸部不適, 呼吸急促, 而有些患者 則沒有任何症狀。
