Method of phase-frequency spectral analysis of electrocardiosignal in problems of home telemedicine

The article presents a method of phase-frequency spectral analysis of an electrocardiogram signal for use in portable arrhythmia detectors. The selection of spectrum values for differentiating between normal and abnormal QRS complexes of the electrocardiogram signal is describe. Sample spectra for various QRS complexes of real life signals are given. We developed an algorithm for detecting arrhythmias and further distinguishing them. The results that was obtained by spectral analysis should be used to prevent the development dangerous type of arrhythmias and their timely exposure detection.
