一、病例选择:近阶段血压稳定升高的患者。二、观察方法:1.根据患者病情轻重及以往治疗情况可酌情在不用其他降压药或维持原降压药及剂量不变的条件下至少观察二周。在观察末期连测三次以上非同日血压,若舒张压相差小于6毫米汞柱则取其平均值作为治疗前血压值,否则需延长观察时间至达到以上要求。2.治疗期间至少每周需测卧、立位血压及心率一次,并记录症状变化及药物的副作用。取停止治疗观察末期三次以上非同日血压值作为治疗后的血压值。3.根据血压及症状的治疗反应决定药物剂量的增减。为了肯定疗效,观察期不应小于一个月(如副作用大,可提前停药,但统计疗效时不列为“无效”病 First, the case selection: stable blood pressure increased in recent stages of patients. Second, the observation method: 1. According to the severity of the patient’s condition and the previous treatment can be discretionary without using other antihypertensive drugs or to maintain the original antihypertensive drugs and dose unchanged at least two weeks observed. In the end of the observation even measured more than three times on non-same day blood pressure, if the diastolic blood pressure difference is less than 6 mm Hg then take the average value as the pre-treatment blood pressure, or need to extend the observation time to meet the above requirements. 2. At least weekly testing should be taken during pregnancy, standing position blood pressure and heart rate once, and record the symptoms and drug side effects. Observe the end of treatment stopped more than three times the value of non-blood pressure after treatment as the blood pressure value. 3. According to the treatment of blood pressure and symptoms of drug response to determine the increase or decrease. In order to confirm the efficacy, observation period should not be less than one month (such as side effects, early withdrawal, but the statistical efficacy is not listed as “invalid” disease
