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.
