A high pressure of 147 and a low pressure of 87 should mean that a systolic blood pressure of 147mmHg and a diastolic blood pressure of 87mmHg are blood pressure abnormalities that need to be confirmed with multiple measurements. Normal blood pressure is not higher than 140/90mmHg, systolic blood pressure 147mmHg, diastolic blood pressure 87mmHg belongs to elevated blood pressure. The diagnostic criteria for hypertension are three or more times, non-same day blood pressure is greater than systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥ 90mmHg can be diagnosed as hypertension. Therefore, the diagnosis of hypertension requires multiple monitoring, and a single increase in blood pressure is not directly diagnostic of hypertension. Blood pressure should be measured in a quiet state after at least 30 minutes of rest. If blood pressure is measured immediately after exercise, the blood pressure value will be high and will not objectively reflect the true blood pressure level. A 24-hour ambulatory blood pressure monitoring can also be performed to calculate the average value, which can be used as the basis for the diagnosis of hypertension. Patients with abnormal blood pressure need to consult a doctor in time for a clear diagnosis and timely treatment under the doctor’s guidance.
