DIAGNOSTIC TECHNIQUE FOR DISEASES OF INTERNAL ORGANS BY MEANS OF MATRIX INFORMATION ANALYSIS OF ELECTRIC CARDIOSIGNALS Russian patent published in 2020 - IPC A61B5/402 A61B5/02 G16H50/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, cardiology, biophysics, diagnostics of non-infectious diseases by means of electrocardiosignal treatment (ECT). Disclosed is a method in which ECT matrix information analysis involves continuous simultaneous removal of 600 electrocardiocycles in 1st, 2nd and 3rd standard Einthoven leads or Goldbergar unipolar reinforced leads from extremities. Duration (D_n) of the QRS-ventricular complexes and the ratio R_n and the subsequent time interval (T_n) representing arctg are determined. α_n, which conditionally reflects the phase deviations (F_n+1) of each subsequent cardiac cycle relative to the previous one (F_n). Measurements are carried out with increase in quantisation frequency up to 10 kHz and more. Array of registered ECS is arranged with the help of "window". In structuring array for the pacemaker via said "window" encoded characters of the Latin alphabet, each fragment structured ECT. Thus, the code of each ECT structural unit in the form of a linear matrix includes three cardiac cycles, which is represented by a sum of four coding symbols. Spatial matrixed codogram is formed, which is a set of linear matrices obtained during coding, which reflect simultaneously three cardiac cycles. Method includes calculating and ranking them according to frequency of occurrence, comparing with standard spatial matrices rates and diseases, which are obtained by the same method and include matrices of only 100 % of occurrence among healthy people or patients with certain specific diseases. Conclusion on the norm or disease is carried out in the presence of a corresponding reference matrix in the linear and spatial matrix code of the examined individual.

EFFECT: method provides more accurate diagnosis of diseases of internal organs of non-infectious nature at any stage of their development with achievement of completeness and objectivity of information analysis of ECT, including all types of modulation of parameters of pulsed signals: amplitude-pulse, interval-pulse or frequency-pulse, long-pulse and phase-pulse modulation.
