自主神经系统控制心跳间隔的波动。自主神经系统由交感神经系统和副交感神经系统组成，交感神经系统增加全身的活动，增加心率和血压。副交感神经系统储存能量，促进胃肠蠕动，降低心率和血压。由于自主神经系统调节内部器官、血管、腺体等，心率变异性是指心率与自主神经系统的控制有关，心率变异性是指心率与自主神经系统的控制有关，心率变异性是指心率与自主神经系统的控制有关，心率变异性是指心率与自主神经系统的控制有关，心率变异性是指心率与自主神经系统的控制有关。通过第3.3节中的心肺相位同步来维持和改善唤醒，以及从近年来使用频率增加的可穿戴终端获得的心率变异性的指标与从传统的R计算的心率变异性的指标之间的比较的示例。R间期见第3.4节。
The autonomic nervous system controls the fluctuation of the heartbeat interval. The autonomic nervous system consists of the sympathetic nervous system and the parasympathetic nervous system, and the sympathetic nervous system increases the activity of the whole body and increases heart rate and blood pressure. The parasympathetic nervous system stores energy, promotes gastrointestinal motility, and decreases heart rate and blood pressure. Since the autonomic nervous system regulates internal organs, blood vessels, glands, etc., regardless of volition, and the heartbeat interval fluctuates under the control of the autonomic nervous system, heart rate variability, which quantifies the characteristics of the fluctuation of the heartbeat interval, has been studied as an evaluation indicator for the mental and physical condition.In this chapter, the representative indicators of heart rate variability are introduced in Sect. 3.2, maintaining and improving arousal by cardiorespiratory phase synchronization in Sect. 3.3, and examples of comparison between the indicators of heart rate variability obtained from wearable terminals whose use frequency is increasing in recent years and the indicators of heart rate variability calculated from the conventional R–R intervals are shown in Sect. 3.4.
