自发性心率波动的频谱分析通过使用自主神经阻滞剂和姿势变化进行评估。仰卧位的低频波动（低于0.12 Hz）完全由副交感神经系统介导。站立时，低频波动增加，并由交感神经系统和副交感神经系统共同介导。高频波动，在呼吸频率，减少站立和介导的副交感神经系统。心率频谱分析是一种功能强大的非侵入性工具，用于量化自主神经系统的活动。
Spectral analysis of spontaneous heart rate fluctuations were assessed by use of autonomic blocking agents and changes in posture. Low-frequency fluctuations (below 0.12 Hz) in the supine position are mediated entirely by the parasympathetic nervous system. On standing, the low-frequency fluctuations increase and are jointly mediated by the sympathetic and parasympathetic nervous systems. High-frequency fluctuations, at the respiratory frequency, are decreased by standing and are mediated solely by the parasympathetic system. Heart rate spectral analysis is a powerful noninvasive tool for quantifying autonomic nervous system activity.
