目的：我们研究的目的是利用呼吸相域分析来研究心率变异性的外在影响。吞咽、咳嗽和发声（大声朗读和谈话）被认为是外在影响。方法：在本研究中，在呼吸期的每π/10 rad处采样瞬时R-R间隔（RRI），并将数据分为三个子集：a)事件发生时的呼吸，b)事件发生后的一次呼吸，c)正常呼吸。计算并比较了呼吸性窦性心律失常（RSA）的平均波形。结果与结论：吞咽引起心动过速，心动过速在一次呼吸后恢复。咳嗽也会引起心动过速，但它不会在一次呼吸中恢复。发声使平均RRI缩短，但发声引起的呼吸模式变化对RRI的振幅无统计学意义。此外，该方法还能有效地分析心率变异性（HRV）的外在影响。
Summary Objectives : The objective of our study is to investigate extrinsic influences on heart rate variability using respiratory-phase domain analysis. Swallowing, coughing and vocalization (reading aloud and conversation) are adopted as extrinsic influences. Methods : In this study, an instantaneous R-R interval (RRI) is sampled at each π/10 rad of the respiratory phase and the data is divided into three subsets: a) respiration with event, b) one respiration after the event, and c) normal respiration. Then the mean waveforms of respiratory sinus arrhythmia (RSA) are calculated and compared. Results and Conclusions : It is found that swallowing induces tachycardia that recovers within one respiration. Coughing also induces tachycardia, but it does not recover within one respiration. Vocalization shortens the mean RRI, but the changing respiratory pattern due to vocalization has no statistically significant influence on the amplitude of RSA. Furthermore, it is found that the proposed method is effective for analyzing extrinsic influences on heart rate variability (HRV).
