本研究旨在探讨心率变异性(HRV)生物反馈对日常生活中睡眠时心肺功能的影响。45名健康青年被随机分为三组：HRV生物反馈组、自体训练组(AT)和不治疗对照组。HRV生物反馈的参与者被要求在习惯性睡前使用手持HRV生物反馈设备，AT的参与者被要求在睡前听录音指导，而对照组的参与者被要求在睡前进行他们的习惯性活动。用腕表式透皮光电传感器连续测量3个时间点的睡眠脉搏波信号。在测量的第一个晚上收集基线数据，然后连续两个晚上进行HRV生物反馈、AT或对照。心肺静息功能以脉率变异性高频成分的幅度作为呼吸窦性心律失常的替代指标进行定量评估。心率变异性生物反馈组睡眠期间HF成分增加，而AT组和对照组保持不变。这些结果提示，睡前心率变异性生物反馈可以改善睡眠期间的心肺功能。
The present study was designed to examine the effect of heart rate variability (HRV) biofeedback on the cardiorespiratory resting function during sleep in daily life. Forty-five healthy young adults were randomly assigned to one of three groups: HRV biofeedback, Autogenic Training (AT), and no-treatment control. Participants in the HRV biofeedback were instructed to use a handheld HRV biofeedback device before their habitual bedtime, those in the AT were asked to listen to an audiotaped instruction before bedtime, and those in the control were asked to engage in their habitual activity before bedtime. Pulse wave signal during sleep at their own residences was measured continuously with a wristwatch-type transdermal photoelectric sensor for three time points. Baseline data were collected on the first night of measurements, followed by two successive nights for HRV biofeedback, AT, or control. Cardiorespiratory resting function was assessed quantitatively as the amplitude of high-frequency (HF) component of pulse rate variability, a surrogate measure of respiratory sinus arrhythmia. HF component increased during sleep in the HRV biofeedback group, although it remained unchanged in the AT and control groups. These results suggest that HRV biofeedback before sleep may improve cardiorespiratory resting function during sleep.
