    穴位电刺激对人体心血管功能的影响

    Effects of electroacupuncture at Point Neiguan on cardiovascular functions in humans

    • 摘要:
        目的  探讨穴位电刺激对正常人体心血管功能的影响。
        方法  20名健康志愿者随机进行对照、电针刺激和非穴位刺激3次试验。对照组仅安静平卧30 min,电针组给予双侧内关穴电针刺激30 min,非穴位组给予双侧前臂非穴位刺激,刺激参数同电针组。连续监测被试者心率变异性和心血管功能变化。
        结果  与对照组和非穴位组相比,电针组低频功率与高频功率比值在电针期间显著升高(P<0.05);心率、每搏量及心排出量有升高趋势,未达到显著水平。
        结论  电针刺激内关穴可以提高交感神经紧张度,调整自主神经的均衡性。

       

      Abstract:
        AIM  To investigate changes of cardiovascular function after electroacupuncture (EA) treatment in healthy volunteers.
        METHODS  Twenty healthy volunteers were randomly allocated to a Control group (no electroacupuncture), an Acupoint group (bilateral EA at Point Neiguan (PC6) for 30 min) and a Non-acupoint group (bilateral EA at a non-acupoint of both shoulders). Heart rate variability (HRV), heart rate, stroke volume (SV) and cardiac output (CO) were measured.
        RESULTS  Heart rate variability analysis revealed that compared with those in the Control group and the Non-acupoint group, EA at PC6 decreased high-frequency ranges of R-R interval and increased low-frequency ranges of R-R interval, indicating an elevated heart sympathetic tone. There was an increasing trend in heart rate, SV and CO, but without significant differences.
        CONCLUSION  EA treatment at Neiguan is highly effective in activating peripheral sympathetic nervous system.
