METHOD OF ESTIMATING FUNCTIONAL STATE OF CARDIO-VASCULAR SYSTEM OF MAN Russian patent published in 2009 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to restorative medicine and balneology. Simultaneously and synchronically for about 10-15 minutes signal of electric cardiogram (ECG) and signal of pulsogram of arterial vessels of microcirculatory channel are registered. After that cardiointervalogram is graphed by ECG data, spectra of cardiointervalogram and pulsogram power are obtained, frequency range of examination is limited by set of frequency constituents from 0.05 Hz to 0.15 Hz. For sorted out constituents time dependences of instantaneous phase of fluctuations, characterising signal recurrence in time for both signals, are found, difference of phases of sorted out cardiointervalogram and pulsogram signals is determined, on phase difference graph time intervals, during which phase difference value remains neat the level of constant value, are found. Then durations of said found time intervals are added, and by ratio of their total duration to total time of ECG and pulsogram signals registration conclusion about state of cardio-vascular system at given time moment is made.

EFFECT: method allows to obtain qualitatively new and more objective information about state of cardio-vascular system, its functional integrity.
