Blood pressure monitoring is an important indicator to assess whether you have hypertension, the average value of blood pressure does not have clinical significance, the normal value of blood pressure is systolic blood pressure of 90 to 139mmHg, diastolic blood pressure of 60 to 89mmHg. At present, the normal value of blood pressure is 90-139mmHg for systolic blood pressure and 60-89mmHg for diastolic blood pressure, which is the normal range of blood pressure. If the systolic blood pressure is ≥140mmHg and/or the diastolic blood pressure is ≥90mmHg, it is possible to be hypertensive.
