心理性应激对不同神经类型者心血管活动的影响

THE INFLVENCES OF PSHCHOLOGICAL STRESS ON HUMAN CARDIOVASCVLAR ACTION OF DIFFERENT NERVOUS TYPE

采用王文英设计的“８０．８”神经类型测试法判别１３２名医学生的神经类型。取全部神经类型强型者与弱型者，分别在生理实验时及考试２周后安静时，测量血压和心率。结果表示，考试时所有被试的收缩压、舒张压均显著升高，心率明显加快。与弱型比，强型者的血压是以舒张压升高为主（Ｐ＜０．０５），脉压减小；而弱型者是以收缩压升高为主，脉压增大，并显著高于强型者（Ｐ＜０．００１）；弱型者心率超过１００次／分的人数明显多于强型者（Ｐ＜０．０５）。但安静时，两种神经类型者的收缩压、舒张压、心率均无明显差异（Ｐ＞０．０５）。揭示心理性应激对不同神经类型者心血管植物性功能有一定的影响，并存在差异，主要是应激时强型者与弱型者在心血管方面反应的敏感器官和机制不同。

Nervous types of 132 medical students were assessed using test of '80.8' nervous type designed by Wang Wenying. All the strong and the weak types were taken from them and their blood pressure and heart rate were measured in the physiological experiment and when they were quiet two weeks after test. The results showed that all systolic pressure diastolic pressure rose and heart rate increased distinctly in the test. Diastolic pressure of strong types was distinctly higher than weak types (P<0.05). Pulse pressure reduced; The weak types mainly had systolic pressure, their pulse pressure increased and there was a significant difference compared with strong types (P<0.01); There were more students whose RH was >100 time/min (P<0.05) in weak types that in strong types. But at rest, it didn't have any significant difference between two the types. This suggests there was a difference between two nervous types to pshchological stress in the effect of cardiovascular autonomic function, it may be different in the acute organ and mechanism of cardovascular reaction.
