  • 摘要:
      目的  运用长程穿戴式动态心电监测记录仪, 通过分析自主神经的昼夜节律与阴阳的关系, 评价其作为一种判断人体阴阳平衡手段的可行性。
      方法  选取健康受试者30例, 将长程穿戴式动态心电监测记录仪贴于受试者胸前, 同步心电监测, 连续佩戴48 h。分析48 h内心率变异性指标如窦性心搏RR间期标准差(SDNN)、RR间期标准差的平均值(SDNN index)、相邻心跳间期差值大于50 ms的个数占总心跳间期数的百分比(pNN50)、频域参数低频功率(LF)、高频功率(HF)、低频/高频比(LF/HF)等, 观察其昼夜节律变化, 分析与阴阳的关系。
      结果  心率变异性各项指标呈现出昼夜变化, 反映人体的昼夜节律: 夜间SDNN、SDNN index、pNN50、HF均高于日间, 差异具有统计学意义(P < 0.05);LF/HF日间高于夜间, 差异具有统计学意义(P < 0.05)。
      结论  长程穿戴式动态心电监测记录仪可以通过监测及分析心率变异性, 反映自主神经的动态变化, 从而判断人体阴阳的平衡关系。

     

    Abstract:
      OBJECTIVE  To evaluate the feasibility of the long-term wearable dynamic ECG monitor as a mean to determine the balance of yin and yang in the human body by analyzing the relationship between the circadian rhythm of autonomic nerves and yin-yang.
      METHODS  A total of 30 healthy volunteers were selected, and a long-term wearable dynamic ECG monitor was placed on their chests for 48 h to complete simultaneous monitoring. In addition, heart rate variability indicators the standard deviation of normal-to-normal intervals (SDNN), the index of the standard deviation of normal-to-normal intervals (SDNN index), the percentage of differences exceeding 50 ms between adjacent normal number of intervals (pNN50) and frequency domain parameters low frequency power (LF), high frequency power (HF), low frequency/high frequency ratio (LF/HF) were used to observe the circadian rhythm changes and analyze the relationship between yin and yang.
      RESULTS  The heart rate variability indicators showed circadian variations, and reflected the circadian rhythm in the human body. SDNN, SDNN index, pNN50 and HF were higher at nighttime than at daytime, and the differences were statistically significant (P < 0.05). However, LF/HF was higher at daytime than at nighttime, and the differences were statistically significant (P < 0.05).
      CONCLUSION  The long-term wearable dynamic ECG monitor can reflect the dynamic changes of autonomic nerves by monitoring and analyzing the heart rate variability, so as to evaluate the balance relationship between yin and yang in the human body.
