Monitoring microalternations the ECG-signal and the analysis the characteristic of flicker-noise

Abstract

In the present message preliminary results of the data of monitoring of parameters ECG dispersion map with the subsequent analysis of the characteristic of flicker-noise (1/f) are submitted. The given inspections of 47 patients have been included in research with a acuter coronary syndrom, surveyed in 1-3 day of disease (middle age - 54,5 ± 8,6 years) which are executed 91 monitoring by duration from 20 up to 90 minutes. At the visual analysis are revealed periodic low amplitude oscillations of values of an index of microalternations from a long wave from 2-5 till 6-15 minutes. Character and a degree of change of microalternations is new diagnostic area of attributes of ECG-diagnostics reflecting the electrophysiological status and «stock» compensatores resources of a myocardium It is shown, that there is a certain dependence of the characteristic 1/f from weight of current of disease, and flicker-noise - has prospect of use as a method possibiliti forecasting.
