Abstract

Holographic processing of electrocardiograms is proposed on the basis of the windowed Fourier transform of the electrocardiosignal that converts it from the time representation to the frequency–time representation, to the modulus squared of which the two-dimensional frequency–time Fourier transform is applied. At the integrated transformation output the spectral density of the signal is localized in the form of focal spots containing information on the temporal distribution of spectral densities of separate waves in the electrocardiogram. Experimental results of holographic processing of electrocardiograms are presented, which are obtained for patients with a normal heart and with congestive heart failure.

心电图全息处理
在对心电信号进行加窗傅里叶变换的基础上,提出了心电图全息处理方法,该方法将心电信号从时间表示转换为频率-时间表示,再转换为模的平方,并对其进行二维频率-时间傅里叶变换。在积分变换输出处,信号的频谱密度以焦点的形式定位,其中包含心电图中各波频谱密度的时间分布信息。本文介绍了正常心脏和充血性心力衰竭患者心电图全息处理的实验结果。
