The brain needs fresh supply of blood to function normally. During an episode of arrhythmia, there is a great possibility that blood pooling in the chambers of the heart may develop micro clots that is carried along the circulation. Consequently, ischemic stroke occurs when an artery to the brain is narrowed by plaque or when it is completely blocked by a thrombus that prevents blood from supplying an area of the brain. The brain tissues deprived of fresh supply of blood die in a matter of minutes. Equally fatal is hemorrhagic stroke where a blood vessel burst causing blood to leak on surrounding tissues resulting to permanent brain
