摘要
目的:检测神门穴针刺前、留针时、出针后心率变异性频域指标的变化,分析针刺神门穴对自主神经功能的影响,以初步探讨神门穴的作用机制。方法:70例受试者均安静休息平躺制动时,用Actiheart心电监测录仪记录针刺前10min、留针时10min、出针后10min的心率变异性频域指标极低频功率(VLF)、低频功率(LF)、高频功率(HF)、低频功率与高频功率之比(LF/HF)的变化情况。通过短程记录分析程序分析后,导出结果,分析针刺前、留针时、出针后各指标的变化规律。结果:针刺前、留针时和出针后的VLF比较,差异有显著性意义(P<0.05)。留针时和出针后VLF与针刺前比较,差异有显著性或非常显著性意义(P<0.05,P<0.01)。针刺前、留针时和出针后的LF比较,差异有非常显著性意义(P<0.01)。留针时和出针后LF与针刺前比较,差异均有非常显著性意义(P<0.01)。针刺前、留针时和出针后的HF比较,差异有非常显著性意义(P<0.01)。留针时HF与针刺前比较,差异有非常显著性意义(P<0.01)。结论:针刺神门穴可引起心脏自主神经功能变化,这些变化可能是神门穴治疗疾病的作用机制之一。
Objective:The changes of heart rate variability frequency domain(HRV-FD) before acupuncture of Shenmen acupoint,during retaining needle and after needle withdrawal were observed to analyze the influence of acupuncture of Shenmen on autonomic nerve function,and to explore its possible therapeutic mechanism.Methods:Seventy subjects lay on their back after taking a rest,and then were connected with the Actiheart electrographic recorder for the observation of HRV-FD parameters 10 min before acupuncture,during retaining needle for 10 min and 10 min after needle withdrawal.HRV-FD parameters included the power of very low frequency(VLF),low frequency(LF) and high frequency(HF),and LF /HF ratio.The changes of HRV-FD parameters were analyzed with short-course record analysis program.Results:The differences of VLF,LF and HG were significant between before acupuncture,during retaining needle and after needle withdrawal(P < 0.05 or P < 0.01).VLF during retaining needle and after needle withdrawal differed from that before acupuncture(P < 0.05 or P < 0.01).LF during retaining needle and after needle withdrawal also differed from that before acupuncture(P < 0.01).HF during retaining needle differed from that before acupuncture(P < 0.01).Conclusion:Acupuncture of Shenmen acupoint can have an effect on autonomic nerve function,which may be one of its therapeutic mechanisms.
