METHOD OF EARLY DIAGNOSTICS OF CARDIOVASCULAR DISEASES ON TO THE BASIS OF MULTICHANNEL SPECTRAL ANALYSIS OF SLOW CT WAVES OF CARDIOSIGNALS

摘要

1. A method for early diagnosis of cardiovascular disease, comprising registrtsii pulse signal by photoelectric conversion in the pad of the thumb of his left hand over for 2 ... 3 min. and its subsequent spectral analysis in three frequency bands of the frequency range of 0.01 ... 0.5 Hz, wherein the pulse signal in synchronization with registration recorded electrocardiosignal, isolated slow waves from these two cardiosignals determine spectra of slow waves of signals, calculating a power spectral coefficients cardiosignals slow waves in the slow component of the 2nd order - from 0.01 to 0.05 Hz in the slow component of the 1st order - from 0.05 to 0.15 Hz in the respiratory component - from 0.15 to 0.5 Hz based on these results form the six informative signs X1 ... X6, cardio recording channels in one of the calculated heart rate, which is used as a seventh feature informative X7, formed and fed semielementny vector informative signs on entrance trained neural network, the outputs of which correspond to the partial class of cardiovascular zabolevaniy.2. A method according to claim 1, characterized in that for the isolation of slow waves of the pulse signal (first channel) represented by the dynamic near Z fotopletizmosignala digital samples, a structure-element set value of 1.3 ... 1.6 cardiosignal middle period, the morphological operation is performed dilation signal Z with a plurality of zero elements produced by a selected strukturoobrazuyusch
