摘要

在这项研究中，记录了10名正常受试者在三种不同呼吸状态下的心音。对这些信号进行了分析，研究了模型参数随呼吸作用的变化。结果表明，在呼吸过程中，模式的频率没有变化，而在吸气和呼气之间，模式的能量有显著差异。研究结果就提出的心音产生机制进行了讨论。

Respiration related changes of PCG model parameters

In this study, heart sounds of 10 normal subjects are recorded in three different respiratory states. These signals are analyzed and the changes of model parameters with respiration are studied. As a result, it is observed that the frequency of modes do not vary during respiration while the energy of modes significantly differ between inspiration and expiration. The results of the study are discussed with respect to proposed heart sound generation mechanisms.
