By utilizing NAITO's analytical indices of the high frequency energy (HFEI) [sigma p x f (0.15 Hz < frequency < 0.45 Hz)] and the low frequency energy (LFEI) [sigma p x f (0.025 Hz < f < 0.15 Hz)] of R-R intervals combined with UEDA's index of fluctuation in propagation time of radial arterial pulses (i.e. R-P intervals), the author investigated relation between elongation in R-R and shortening in R-P intervals by application of electrical acupuncture (1 Hz) on traditional acupoints (HT7:SHENMEN and PC4: XIMEN). The spectral heart rate analyses have been performed in 16 males and 14 females (total 30, i.e. 18 physically healthy volunteers and 12 patients). Those who were suffering from any cardiovascular diseases were excluded. Results obtained are as follows; (1) The mean R-R intervals were significantly prolonged from 10 minutes after needle insertion to the end, i.e. 10 minutes after removal of the needles. (2) The R-P intervals were significantly shortened after 10 minutes of needle insertion. It is assumed that the decrease in heart rate by acupuncture was due to relative superiority of the vagal tone and the shortened R-P intervals, and was due to sympathetic nerve activities stimulated by acupuncture, so as to expedite arterial pulse wave propagation by the arterial contraction. Thus, increased activities of both sympathetic and vagal nerves can coexist simultaneously during acupuncture.
通过利用内藤的高频能量分析指标（HFEI）[σp×f（0.15赫兹＜频率＜0.45赫兹）]和R-R间期的低频能量分析指标（LFEI）[σp×f（0.025赫兹＜f＜0.15赫兹）]，并结合上田的桡动脉脉搏传播时间波动指标（即R-P间期），作者通过在传统穴位（HT7：神门和PC4：郄门）上施加电针（1赫兹），研究了R-R间期延长与R-P间期缩短之间的关系。对16名男性和14名女性（共30人，即18名身体健康的志愿者和12名患者）进行了频谱心率分析。排除患有任何心血管疾病的人。获得的结果如下：（1）从进针后10分钟到结束，即拔针后10分钟，平均R-R间期显著延长。（2）进针10分钟后，R-P间期显著缩短。据推测，针刺引起的心率下降归因于迷走神经张力的相对优势以及R-P间期的缩短，并且归因于针刺刺激交感神经活动，从而通过动脉收缩加快动脉脉搏波传播。因此，针刺过程中交感神经和迷走神经的活动增加可以同时并存。
