Cerebral infarction is caused by blood supply obstacle in local brain tissue area, resulting in ischemic and hypoxic lesion and necrosis of brain tissue. Patients with cerebral infarction are prone to cardiac arrhythmia, which may be caused by excessive exercise, heart failure and so on. 1. Excessive exercise: Excessive exercise can induce insufficient blood supply to the heart, resulting in arrhythmia, shortness of breath, rapid heartbeat, panic and other symptoms, which can be relieved by appropriate rest. 2. Heart failure: heart failure in patients with cerebral infarction leads to arrhythmia caused by reduced blood supply to the heart. Symptoms such as chest tightness, shortness of breath, fatigue and rapid heartbeat will occur. Cerebral infarction patients should maintain emotional stability in daily life, moderate exercise, but also a light diet, do not eat spicy and stimulating food, eat more fresh fruits and vegetables.
