What is exercise induced syncope? What causes syncope, which is common during exercise?

1 Decreased cardiac output. For those who usually lack exercise, they suddenly participate in a larger amount of exercise, and their heart function cannot keep up with the needs of exercise for a while, coupled with the lack of training, uncoordinated movements, breath-holding, etc., resulting in a decrease in blood return. Cardiac output is also markedly reduced, resulting in transient cerebral ischemia.

And due to the lack of exercise, the body is less able to adapt to this situation, and it is more likely to faint.

2 Gravitational shock. For example, standing still for a long time, squatting for a long time and suddenly getting up, and suddenly stopping activities after running, etc., can reduce the blood return flow due to gravity, and cerebral ischemia can be formed.

Transient loss of consciousness during or after exercise, called exercise-induced syncope, is caused by a sudden ischemia of the brain and is more common in adolescents with low levels of training.

a) Causes. 1 Decreased cardiac output.

b) Performance. First, there are prodromal symptoms such as general fatigue, dizziness, tinnitus, blackness in front of the eyes, and paleness, followed by loss of consciousness, sudden fall to the ground, and symptoms such as cold hands and feet, slow and weak pulse, decreased blood pressure, slow breathing, and miosed pupils. In mild cases, after falling to the ground, the brain is replenished with blood, so that the ischemia is eliminated, and they can wake up in a moment, but they still have dizziness, poor spirit, fatigue and other feelings after waking up.

If they are elderly or patients with chronic diseases such as hypertension and diabetes, they should pay attention to ruling out cardiovascular and cerebrovascular diseases such as cerebral hemorrhage, cerebral infarction, and myocardial infarction, and they should go to the hospital in time for brain scan or MRI to determine whether there is a slight cerebral leakage. During the remission period, it is necessary to pay attention to rest, moderate exercise and vestibular ** training, daily routine, maintain an optimistic mood, eat a low-salt diet and drink moderate water, and relax**.

First of all, the patient needs to lie on his back, raise his lower limbs to increase cerebral blood flow, loosen the collar and trouser belt, turn his head to one side, give oxygen if necessary, and acupressure or acupuncture points such as Renzhong, Yongquan, Hegu or smell ammonia to promote awakening, and after consciousness is restored, he can sit up slowly, and then stand up slowly, but at least need to rest for 30 minutes before standing up.
