交叉光谱技术被用来描述[人类]呼吸频率、窦性心律和外周血流量之间的关系。呼吸频率在一定范围内调节窦性心律和外周血流量，具有特征频率振幅模式，并在设定范围内携带Traube-Hering-Maver波。超过0.4 Hz（24呼吸分钟-1）的上限，就不会发生调制。这些受试者的呼吸下限估计为0.033 Hz(2呼吸分钟-1)；调制的下限为。apprx。0.05 Hz(3次呼吸分-1)，大多数个体。这些观察结果对窦性心律< 90拍/分钟-1时的心率测量具有重要意义。
Cross-spectrum techniques were used to characterize the relationships between [human] breathing rate, sinus rhythm and peripheral blood flow. Breathing rate modulates sinus rhythm and peripheral blood flow between certain limits, with a characteristic frequency amplitude pattern and entrains the Traube-Hering-Maver waves within set limits. Beyond the upper limit of 0.4 Hz (24 breath min-1) no modulation occurs. The lower limit was estimated in these subjects able to breathe at rates of 0.033 Hz (2 breath min-1); the lower limit of modulation is .apprx. 0.05 Hz (3 breath min-1), in most individuals. These observations have serious implications for heart rate measurements in sinus rhythm < 90 beat min-1.
