FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely to devices for registration, analysis and transmission of electric cardiosignal (ECS). Device for ECS registration contains successively connected amplifier and analogue-digital converter with multiplexor, as well as arithmetic device, two memory units, digital modem, analyser of increment codes, counter of increment code number, first unit of switching, control unit. Device for ECS registration differs from those known from the equipment level by introduction into it of successively connected decomposition unit and second arithmetic-logic device. Decomposition unit contains second unit of switching, two adders, two units for extremum determination, two interpolation filters and register. Decomposition unit is intended for realisation of step-by-step mode of signal decomposition into empiric modes. Second arithmetic-logic device is intended for checking conditions of stop of signal decomposition process, storage and summing up obtained empiric modes. ^ EFFECT: application of claimed invention will make it possible to qualitatively suppress noise of various types, efficiently detect and classify informative ECS sections (complexes, teeth, intervals) and measure their parameters with high accuracy. ^ 2 cl, 8 dwg |
