Detecting The R Wave in the ECG Based on High-order Statistics

心电信号的检测对于临床心脏疾病的检验和确诊有很重要的作用,所以目前有关心电信号检测方法的研究很多。本文针对心电信号R波的检测,采用了一种基于高阶统计量的检测方法。使用MATLAB编程软件实现了心电信号R波检测,采用非参数直接法心电信号R波进行双谱估计,并将实验运行结果作以比较。实验结果表明高阶统计量是一种十分有效的信号检测和系统分析方法。

Since the ECG signal detection is important to the inspection and diagnosis of the heart disease,many methods for detection have been developed.This article presents a method to detect the R wave in the ECG.Including the non-Gaussian signal,the methods were realized by programming the MATLAB.It performs the double-spectrum estimations on the signal detection,realized by the direct,self-correlated function method.Finally,the results were compared.The results shows that the high-order statistics method is an effective method for signal detection and analysia.
