High pressure of 120mmHg in the morning, low pressure of 79mmHg is normal blood pressure. The so-called high pressure is the systolic blood pressure, is in the middle of the ventricular systole aortic pressure rises sharply to reach the peak, the normal value <120mmHg, the normal high value of systolic blood pressure 120~139mmHg; low pressure is the diastolic blood pressure, is in the end of diastole arterial blood pressure of the lowest value, the normal value <80mmHg, the normal high value of diastolic blood pressure 80~89mmHg. 120/79mmHg is a normal blood pressure in the morning. 79mmHg belongs to the normal blood pressure. The most common blood pressure abnormality is hypertension. Blood pressure measurements are taken three times on different days, and if the systolic blood pressure is always ≥ 140 mmHg and/or diastolic blood pressure is always ≥ 90 mmHg, the diagnosis of hypertension is made, and there are primary hypertension and secondary hypertension. It is recommended that patients with hypertension follow their doctors to take antihypertensive medications for long-term blood pressure control, while lifestyle interventions are preferred for conditioning. Good management of vascular control is very important for the prevention of cardiovascular and cerebrovascular diseases, renal function damage, fundus damage and so on.
