Orthostatic change of systolic blood pressure was consecutively recorded using oscillometric method in 140 normal persons aged twenties to eighties and analyzed by age and sex. Systolic blood pressure generally increased after standing. The men, especially over the age of 50, failed to increase blood pressure immediately after standing (initial 1-3 minutes), and then increased. In the women, on the other hand, blood pressure generally increased after standing. The mean ratio of the blood pressure elevation for 10 minutes was higher in the women than in the men over 50 years old. Systolic blood pressure tended to fall immediately after the second supine from standing in both sexes. In conclusion, age and sex may influence orthostatic change of blood pressure.
采用示波法连续记录了140名年龄在二十多岁至八十多岁的正常人的收缩压体位变化，并按年龄和性别进行了分析。站立后收缩压一般会升高。男性，尤其是50岁以上者，站立后即刻（最初1 - 3分钟）血压未能升高，随后才升高。另一方面，女性站立后血压一般会升高。50岁以上女性站立后10分钟血压升高的平均比率高于男性。两性从站立位第二次仰卧后收缩压往往会立即下降。总之，年龄和性别可能会影响血压的体位变化。
