标题： Disentangling Respiratory Sinus Arrhythmia in Heart Rate Variability Records

摘要： 心率变异性的不同测量方法，尤其是呼吸窦性心律失常的测量方法，在研究和临床应用中被广泛使用。 受耦合振子理论思想的启发，我们使用同时测量的呼吸和心脏活动，对心率变异性进行非线性分解，分为与呼吸相关的成分和其他成分。 我们建议将该技术作为通用的预处理工具，既可用于分析呼吸对心率的影响，也可用于其他因素对心率变异性影响的研究。 理论考虑通过25个健康受试者的数据分析进行了说明。 显示英文摘要

摘要： Different measures of heart rate variability and particularly of respiratory sinus arrhythmia are widely used in research and clinical applications. Inspired by the ideas from the theory of coupled oscillators, we use simultaneous measurements of respiratory and cardiac activity to perform a nonlinear decomposition of the heart rate variability into the respiratory-related component and the rest. We suggest to exploit the technique as a universal preprocessing tool, both for the analysis of respiratory influence on the heart rate as well as in cases when effects of other factors on the heart rate variability are in focus. The theoretical consideration is illustrated by the analysis of 25 data sets from healthy subjects.
