A high blood pressure of 150-100, i.e., a systolic blood pressure of 150 mmHg and a diastolic blood pressure of 100 mmHg, is abnormal and is classified as first-degree hypertension. The normal values for blood pressure are 90-139mmHg systolic and 60-89mmHg diastolic. if the systolic blood pressure of 150mmHg and diastolic blood pressure of 100mmHg is higher than normal, it is classified as first-degree hypertension, and is therefore abnormal. The diagnosis of hypertension cannot be based on this one measurement alone. Generally, hypertension can be diagnosed with 3 measurements in the office on non-same day exceeding 140/90 mmHg, or with 24-h ambulatory blood pressure ≥ 130/80 mmHg. Patients with Grade 1 hypertension are recommended to maintain low salt and low fat, eat more fresh vegetables and fruits, strengthen physical exercise, and actively improve their lifestyles. Take antihypertensive drugs as prescribed by the doctor if necessary. If measurement reveals abnormal blood pressure, it is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance.
