心率的波动会影响自主神经的活动规律。研究表明,影响心事的一个主要因素是呼吸。呼吸性心率失常(RSA)能作为反映自主功能的一种无创方法。然而,心率的自主控制频带很宽(一般从ac～0.3Hz),
Heart rate fluctuations will affect the activity of autonomic rules. Research shows that one of the major factors affecting mindset is breathing. Respiratory arrhythmias (RSA) can serve as a noninvasive method of reflecting autonomous function. However, the autonomic control of heart rate is very wide (usually from ac ~ 0.3Hz)
