呼吸性窦性心律失常的检查。正弦呼吸在很宽的频率范围内变化，并观察伴随的心率波动的幅度和相位。这些数据表明，心率不一定如前所述与呼吸同相，而是心率波动与呼吸之间的相位角以特征方式随呼吸频率而变化。呼吸性窦性心律失常的通常描述被认为是不充分的，因为它们被证明只代表整个频率响应曲线上的一个点，该曲线将呼吸率与窦性心律失常相关联。
An examination of respiratory sinus arrhythmia is presented. Sinusoidal breathing was varied over a wide frequency range and the amplitude and phase of the accompanying fluctuations of heart rate were observed. These data show that heart rate is not necessarily in phase with respiration as previously described, but rather that the phase angle between heart rate fluctuations and respiration varies with frequency of breathing in a characteristic fashion. The usual descriptions of respiratory sinus arrhythmia are judged to be inadequate since they are shown to represent only a single point on the entire frequency response curve correlating breathing rate with sinus arrhythmia.
