频谱心电图(FCG),即心电信号的功率谱估计图,是一种心脏检查新技术。本文首先在Welch法、自相关法和Burg法中选取综合性能比较好的Burg法作为谱估计方法,其次通过对几种心电图信号的Burg法谱估计结果作分析,发现频谱心电图对病症敏感性强,对心血管疾病的早期诊断有一定的临床意义。相关结果用Matlab仿真。
Spectral Electrocardiogram (FCG), a power spectrum estimation of ECG signal, is a new technique of cardiac examination. In this paper, Burg method with good comprehensive performance is selected as the method of spectrum estimation by Welch method, autocorrelation method and Burg method. Secondly, the results of Burg method estimation of several ECG signals are analyzed. It is found that the spectrum electrocardiogram is sensitive to the disease , The early diagnosis of cardiovascular disease has some clinical significance. Related results using Matlab simulation.
