摘要：本文从肺容积曲线的分析信号中评估了不同呼吸模式下自发性呼吸和有节奏呼吸时心率的呼吸调节，即呼吸性窦性心律失常（RSA）。无论呼吸方式如何，甚至包括自发呼吸，在相域中RSA的幅度和波形都是相似的。对心跳与呼吸期的关系的研究显示，最近在文献中报道的同步模式（Nature 392: 239, 1998）是在有节奏的呼吸和屏气期间观察到的，呼吸期的进展更慢。结果表明，相域方法可用于提取自发性呼吸过程中的RSA，并有助于阐明RSA的详细机制。然而，在研究心肺耦合时应谨慎使用该技术，因为结果可能受到呼吸模式的影响。
Abstract: We evaluated the respiratory modulation of heart rate, i.e., respiratory sinus arrhythmia (RSA), with respect to respiratory phase derived from an analytic signal from the lung volume curve, during spontaneous breathing and paced breathing with different patterns. The magnitudes and waveforms of RSA in the phase domain were similar regardless of breathing pattern, even including spontaneous breathing. An examination of the occurrence of heart beats with respect to the respiratory phase revealed that synchronized patterns recently reported in the literature (Nature 392: 239, 1998) were observed during paced breathing with breath holding periods whereby the respiratory phase advanced more slowly. It was concluded that the phase domain approach might be useful in extracting RSA during spontaneous breathing and for elucidating detailed mechanisms for RSA. However, the use of this technique for studies investigating cardio-respiratory coupling should be approached cautiously, as the results may be influenced by breathing patterns.
