What is atrial fibrillation?
Atrial fibrillation is a condition when there is sparse stimulation of the atrium, which can affect the atrium systole. The heart will beat fast and irregular. The complication of atrial fibrillation is that there is a reduction of blood pumping to the heart. If not receiving the proper treatment, it will eventually lead to a heart attack. The residual of blood in the atrium can cause a blood clot that can flow to obstruct the cerebral artery higher than in normal people by up to 5 times, which can lead to death.
