Sometimes the blood pressure and/or heart rate will slow down. This kind of syncope is usually under the guidance of a doctor. Most people can cure it through special exercises, and a few people need medication. or pacemaker therapy. Reason 2: Cerebral syncope is caused by a circulatory disorder in the blood vessels of the brain or the blood vessels that mainly supply blood to the brain, resulting in temporary widespread insufficient blood supply to the brain. More common in the elderly, common causes include transient cerebral ischemia, brainstem syncope, Takayasu arteritis, etc. Preventive measures include preventing cerebral arteriosclerosis, reducing cerebral vasospasm, regular medication, and regular review. Reason 3: Cardiogenic syncope refers to syncope caused by sudden reduction or suspension of cardiac output caused by heart disease, mostly caused by arrhythmia and organic heart disease. Common arrhythmias are caused by bradycardia or asystole such as sick sinus syndrome and atrioventricular block, and tachycardia arrhythmias such as ventricular fibrillation and ventricular tachycardia, which lead to reduced cardiac output and cause syncope. Structural heart disease, such as acute myocardial infarction, cardiac myxoma, hypertrophic obstructive cardiomyopathy, congenital cyanotic heart disease, etc., can cause syncope. Cardiogenic syncope is common in the elderly, lasts for a long time, and the condition is dangerous. Elderly people with heart diseases should communicate with cardiovascular specialists for treatment. If necessary, use pacemakers and implantable cardioverter-defibrillators. . Reason 4: Orthostatic hypotensive syncope is more common in the elderly or those who are bedridden for a long time. It manifests as black eyes, syncope, etc. after a sudden change in blood pressure. Preventive measures include standing up slowly or holding on to objects, and not squatting for long periods of time. Traditional Chinese medicine experts remind that there are many causes of syncope, with vasovagal syncope being the most common and cardiogenic syncope the most dangerous. During an attack, the person with syncope should be placed in a supine position or with the lower limbs elevated to increase cerebral blood flow. Loosen the collar and turn your head to one side. Send the patient to the hospital promptly, and perform electrocardiogram, cardiac ultrasound, head CT, blood sugar, tilt test and other examinations according to different situations.

The hot weather in summer leads to a poor digestive system, a large reduction in food intake, and a decrease in blood pressure. If you feel faint when you squat down, it is obvious sexual hypotension. Temporary low blood pressure can lead to insufficient blood supply to the brain, which can lead to headaches, dizziness, or direct fainting, black eyes, and dizziness.
