Abstract

Over the last decade, Computer-Aided Diagnosis (CAD) systems have been provided significant research focus by researchers. CAD systems have been developed in order to minimise visual errors, to compensate manual interpretation, and to help medical staff to take decisions swiftly. These systems have been considered as powerful tools for a reliable, automatic, and low-cost monitoring and diagnosis. CAD systems are based on analysis and classification of several physiological signals for detecting and assessing different diseases related to the corresponding organ. The implementation of these systems requires the application of several advanced signal processing techniques. Specifically, in cardiology, CAD systems have achieved promising results in providing an accurate and rapid detection of cardiovascular diseases (CVDs). Particularly, the number of works on signal processing field for impedance cardiography (ICG) signals starts to grow slowly in recent years. This paper presents a review study of signal processing techniques applied to the ICG signal for the denoising, the analysis, the classification and the characterisation purposes. This review is intended to provide researchers with a broad overview of the currently used signal processing techniques for ICG signal analysis, as well as to improve future research by applying other recent advanced methods.

应用于阻抗心电图ICG信号的信号处理技术综述。
在过去的十年中,计算机辅助诊断(CAD)系统已成为研究人员的重要研究热点。CAD系统的开发是为了最大限度地减少视觉误差,弥补人工解释,并帮助医务人员迅速做出决定。这些系统被认为是可靠、自动、低成本监测和诊断的强大工具。CAD系统是基于对几种生理信号的分析和分类,以检测和评估与相应器官相关的不同疾病。这些系统的实现需要应用几种先进的信号处理技术。具体来说,在心脏病学领域,CAD系统在提供准确、快速的心血管疾病检测方面取得了可喜的成果。特别是阻抗心电图(ICG)信号处理领域的研究近年来开始缓慢增长。本文综述了应用于ICG信号去噪、分析、分类和表征的信号处理技术。本综述旨在为研究人员提供目前用于ICG信号分析的信号处理技术的广泛概述,并通过应用其他最新的先进方法来改进未来的研究。
