The rapid heartbeat upon exercise after a cerebral infarction is considered to be related to the regulation of the cardiovascular center.
Under normal circumstances, when exercising, the body’s blood will be filled to the skeletal muscles, resulting in a reduction of blood in the blood vessels of the heart and brain, and then the arteries will be narrowed in order to maintain the blood pressure and blood flow, so as to ensure the supply of oxygen.
Patients with cerebral infarction usually have hardened and narrowed cerebral blood vessels, and the reduction in cerebrovascular blood during exercise prevents the blood vessels from maintaining blood pressure and blood flow, which may lead to hypoxia in the heart and brain.
Hypoxia can feedback stimulation carotid artery body and aortic body produce cardiovascular reflex to the cardiovascular center, so as to excite the cardiovascular activity neurons, so that the patient’s heart rate increases, blood pressure rises, to maintain cardio-cerebral oxygen supply.
Patients after cerebral infarction should be under the guidance of the doctor to carry out rehabilitation exercise, pay attention to the amount and moderation, do not rush, so as not to aggravate the condition.
