torry blood pressures (ABP) were measured by ambulatory blood pressure monitoring (ABPM) in22 patients with stage I essential hypertension (EH).51 patients with stagge?EH and 35 patients with stageⅢEH. The results indicated that ABP values in EH agreed with the criteria suggested by White more than of40 % of awake BP readings>18.6/12.0kPa and asleep BP readings>16.0/10.6kPa’ . Therefore
the author suggestthat diagnostic criteria of ambulatory hypertension may prefer to the ABP mean values which reported by Wei-Zhong Zhang
