FIELD: medicine; cardiology.
SUBSTANCE: device for registering electric cardiosignals has amplifier, analog-to-digital converter with multiplexer and arithmetic unit as well as increment code analyzer, switch unit, digital modem, increment code number counter, memory unit, control unit, heart electro-motive force vector projection forming unit, heart electro-motive force vector value determination unit and heart electro-motive force vector direction determination unit. Device has widened functional capabilities of electric cartographic testing by means of finding spatial disposition of electric axis of heart. Projection of heart vector to frontal plane is found from standard abstracts from extremities and to horizontal plane - from chest abstracts. Projection of vector of heart to sagittal plane is determined from projections of vector of heart to frontal and horizontal planes. Direction and value of projection of heart electro-motive force is determined from known projections in three-dimensional space.
EFFECT: improved efficiency.
