电针内关与阴经,阳经五输穴对正常人左心功能的效应差异

将正常在校学生７２人按十二经脉分为１２个实验组，采用同一的６×６拉丁方实验设计，在同等条件下观察了电针阴经、阳经五输穴和内关穴对正常青年人心脏收缩时间间期（ＳＴＩ）的效应差异。结果表明，在正常生理状态下，内关穴仍能特异地对左心功能施加影响；而内关穴与阴经、阳经五输穴之间以及阴经、阳经五输穴本身之间，则存在着一定的差异性。

Difference between Electroacupuncture or Neighan (PC6)and Five Shu Points on Yin-Channels and Yang-Channels in Effects on Left Cardiac Function in the Normal Human Being

Twelve channels were assigned to 12 groups and latin sequare design was adopted. At the same condition,difference between electroacupuncture of five Shu points on Yin-channels and Yang-channels and Neiguan point(PC6) in the effects on systolic time intervals(STI)was observed in normal young people. Results show that in normal physiologic state Neiguan point has a specific effect on left ventricular function and there is a certain difference between Neiguan point and the five Shu points of the Yin-channels and the Yang-channels and between the five Shu points of the Yin-channels and the yang-Channels.
