为了降低服用抗精神病药物患者体位性低血压的发生率，对62例精神分裂症患者在增药期间，取不同体位进行了血压和心率的测量。结果：平卧位的收缩压、舒张压、心率与直立位比较（经配对t检验）差异有非常显著性（P＜0．01）。直立位与平卧位相比，心率平均快41次／min，舒张压平均高1．1kPa，而收缩压平均低1．32kPa。其中有5例患者平卧位收缩压正常，而直立位时收缩压＜12kPa。作者提出：①给服用抗精神病药物患者测量血压、心率时，应分别取平卧和直立位进行测量，才能了解患者血压和心率的变化。②增药期间应采取直立位测量，对预防体位性低血压有重要意义。
In order to reduce the incidence of orthostatic hypotension in patients taking antipsychotics, 62 patients with schizophrenia were measured for blood pressure and heart rate during different phases of remission. Results: The supine position systolic blood pressure, diastolic blood pressure, heart rate and upright position (paired t test) the difference was significant (P <0.01). Compared with the supine position, the heart rate averaged 41 beats / min on average, diastolic blood pressure was 1.1 kPa on average, and systolic blood pressure was 1.32 kPa lower on average. Among them, 5 patients had normal supine systolic pressure and systolic pressure <12 kPa in upright position. The authors propose: ① to take antipsychotic patients to measure blood pressure, heart rate, supine and upright position should be taken separately to measure, in order to understand the changes in patients with blood pressure and heart rate. ② during the increase should be taken during orthostatic measurement, to prevent orthostatic hypotension is of great significance.
