In addition, systolic blood pressure increase with the rise, and had normal blood pressure and hypertension boundary demarcation is not easy. 1979 China revised method of measuring blood pressure and hypertension diagnostic criteria are as follows : 1. After a 15-minute break. admission seating right arm blood pressure measurement, the measurement should be repeated several times until blood pressure is relatively stable. DBP to prevail voices disappear, such as the persistent voices disappear, it changes the sound when using numerical. The same one-hour intervals days, or every other day again verified. 2. Where systolic blood pressure ≥ 21.2kPa (160mmHg) and (or) DBP ≥ 12.6kPa (9 5mmHg), the diagnosis can be verified. BP 18.7 ~ ~ 12.6kPa 21.2/12 (140 ~ ~ 95mmHg 160/90 ) for the clinical hypertension. 3. Past history of hypertension, not for more than three months, the current inspection normal blood pressure were not included hypertension; As always this medication and check blood pressure normal, the diagnosis of hypertension should be.
