FIELD: medical engineering. ^ SUBSTANCE: method involves determining resonant resistance and resonant capacity of the oscillatory contour having inductance coil and capacitor. The method is carried out in two phases - without influence and under influence of biological object on oscillatory contour, followed by comparison of active and reactive component values of oscillatory contour in mentioned two phases. Oscillatory contour parameters estimation is carried out by measuring arising free oscillations frequency and their attenuation rates when applying shock excitation to the contour, and oscillatory contour parameters of synchronously with electrocardiosignal measurements done in discrete mode during each of N cardiac cycle time measurements. The device has gage device having inductance coil and capacitor forming an oscillatory contour, linkage device which output is connected to the oscillatory contour, buffer amplifier, analog-to-digital converter and computer with interface means. The device also has the first program-controlled microcontroller input/output group additionally connected to interface output. The second group of microcontroller inputs-outputs is connected to an output of the analog-digital converter. Analog-digital converter input is connected to buffer amplifier output. Buffer amplifier input is connected to the first inductance coil lead. One of microcontroller outputs is connected to linkage device input. The second inductance coil and capacitor leads are connected to the common bus. Electrocardiosignal gauge output is connected to the second analog-to-digital converter input. Its output is connected to the third group of inputs-outputs of the microcontroller. ^ EFFECT: raise accuracy and speed of measurements with simultaneous expansion of functionalities. ^ 3 cl, 2 dwg |
