本研究以心经各穴位的心率变异性（HRV）、脉率变异性（PRV）和人体皮肤电导（SC）为指标，评价电针对膀胱经（BL 15）穴位的影响。选择10名健康志愿者（23 ~ 6岁），第1天作为对照组，第2天作为实验组。对照组在实验过程中接受假电针，实验组在实验过程中接受2 Hz电针刺激BL 15穴10 min。采用心电图（ECG）、腕式血压脉搏计和皮肤电传导反应（SCR）仪分别测定两组刺激前后的心率变异性（HRV）、伪心率变异性（PRV）和皮肤电传导反应（SCR）。从心电图和脉压图的频谱分析发现，电针BL 15可使HRV和PRV的归一化高频功率（nHFP）分量显著增加，而归一化低频功率（nLFP）分量显著降低（p < 0.05）。此外，在ECG和PRV的时域分析中，心率和脉率都降低了。此外，刺激后，大多数穴位的SCR值降低。这些结果还表明，电针BL 15可引起放松、平静和减轻紧张或痛苦的感觉。
In this research, heart rate variability (HRV), pulse rate variability (PRV) and human skin conductance (SC) of all acupoints on Heart Meridian were used to evaluate the effects of electrical acupuncture (EA) on acupoint BL15 (Bladder Meridian). Ten healthy volunteers (aged 23 6) were selected as the control group on the first day, and then used again as the experimental group on the second day. The control group received sham EA during the study, while subjects of the experimental group were stimulated by 2 Hz EA on acupoint BL15 for 10 minutes. Electrocardiogram (ECG), wrist blood pressure pulse meter and skin conductance response (SCR) device were used to measure and analyze HRV, PRV and SCR for the two groups before and after stimulation. From the spectrum analysis of ECG and pulse pressure graph, we found that the EA applied on BL15 could induce a significant increase in the normalized high frequency power (nHFP) component of HRV and PRV, as well as a significant decrease in the normalized low frequency power (nLFP) part (p < 0.05). Moreover, both the heart rate and pulse rate were reduced in the analysis of the time domain of ECG and PRV. Furthermore, most of the SCR values at acupoints were decreased after stimulation. These results also indicate that the stimulation of BL15 by EA could cause relaxation, calmness and reduce feeling of tension or distress.
