The correct name for high pressure should be systolic pressure, and the correct name for low pressure should be diastolic pressure. A systolic pressure of 138 mmHg and a diastolic pressure of 98 mmHg is mild hypertension according to the classification and standard of blood pressure adopted by our country, and it is not normal. According to the classification and standard of hypertension adopted in China, hypertension is defined as systolic blood pressure greater than or equal to 140 mmHg and/or diastolic blood pressure greater than or equal to 90 mmHg measured three times at different time intervals without the use of antihypertensive drugs. A systolic blood pressure of 138 mmHg and a diastolic blood pressure of 98 mmHg, where the systolic blood pressure is in the normal range but the diastolic blood pressure is higher than 90 mmHg, is considered to be mild hypertension (grade 1 hypertension). If the patient’s self-measurement of blood pressure is abnormal, it is recommended to go to the hospital for medical treatment, and use standardized medication to control blood pressure under the guidance of the doctor.
