意念与呼吸周期的不同组合方式对心率变异的影响

应用Ｒ间期频谱分析方法，观察了不同调息形式下的心率变异特点。３２名志愿者的实验结果表明，意念与呼吸周期的不同组合方式能对植物神经功能产生不同影响：当着意于吸气时，可在保持植物神经功能平衡情况下，同时增强交感与迷走神经的活动；而当着意于呼气时，则能显著降低迷走神经的功能，致使明显改变植物神经功能的平衡方向。

Influence of Different Combination of Mental Activity and Respiratory Cycle on Heart Rate Variability

By means of spectral analysis of P-R interval, different characteristics of heart rate variability in different form of respiratory exercise was observed. The results of observation on 32 volunteers showed that mental activity that affected respiration can influence che function of autonomic nerve system in a different way, When the mind was concentrated at the inspiration, the function of autonomic nerve system was kept in balance, and both the sympathetic and the vagal activities enhanced significantly and while mind concentrated at the expiration could induce a reduction of vagal activity so as to produce marked change in the sympathovagal balance.
