摘要

心音图的联合时频表示使心音的基本特征和其他对诊断很重要的生理变化与时间和频域相比更加明显。本文讨论了在这种表示中提取相关成分的可能性。由于改进的目视检查和快速数字信号处理能力,可以为计算机辅助听诊、生理监测系统和计算机辅助心脏病诊断系统提供一些额外的工具。

Joint time-frequency analysis of phonocardiograms
Joint time-frequency representations of phonocardiograms enable fundamental characteristics of heart sounds and other physiological changes important for diagnostics to be more visible compared to time and frequency domain, separately. This paper discuss possibilities for relevant component extraction in such representations. Due to improved visual inspection and fast digital signal processing capabilities, a number of additional tools may be provided for the purpose of computer-aided auscultation, physiological monitoring systems and computer-aided cardiological diagnostic systems.
