Blood pressure can be divided into systolic and diastolic blood pressure, if the systolic blood pressure is 137mmHg, then it is normal; but if the diastolic blood pressure is 137mmHg for a long time, then it is abnormal. Blood pressure is the pressure of blood on the blood vessel wall, generally can be divided into arterial blood pressure, venous blood pressure, capillary blood pressure, but in daily life said blood pressure is generally arterial blood pressure; according to “Internal Medicine” “Diagnostics” can be seen, at present, commonly used in the clinical blood pressure standard: the normal range of systolic blood pressure is 90 ~ 139mmHg, diastolic blood pressure normal range is 60-89mmHg. When the patient’s diastolic blood pressure for a long time > 90mmHg, generally suggests that the patient may have hypertension, need to pay attention to, in addition to timely symptomatic treatment, but also need to test their own dynamic blood pressure on time; but when only occasional transient diastolic blood pressure is too high, generally in a few moments of rest, can be restored. It can be seen that blood pressure is closely related to human health, once patients find that their blood pressure fluctuation is abnormal or long-term value is abnormal, they must go to the hospital as soon as possible to find out the cause of the disease and carry out the treatment to avoid further development of the disease.
