Hypotension is clinically known as diastolic blood pressure. If the diastolic blood pressure is too high, beta receptor blockers are generally used, because the increase of diastolic blood pressure is often caused by the increase of peripheral vascular resistance, the increase of cardiac stroke volume and the acceleration of heart rate. However, β receptor blockers can stimulate sympathetic nerve reflex of cardiac function receptors, reduce vasoconstriction and peripheral resistance, and achieve antihypertensive effect. Clinically, beta blockers are used frequently, especially in mild and moderate hypertensive patients, and they are first-line drugs. In the process of medication, attention should also be paid to changing the lifestyle, including low salt and low-fat diet, smoking and drinking cessation, regular meals, and not overeating. Get enough sleep and stick to physical exercise, which is better.
