Device has micro-vibration transducer and spectrum analyzer connected to visual recording device. The micro-vibration transducer is designed as electronic phonendoscope having pass band of 1-300 Hz. The visual recording device records variations of total micro-vibration spectral power in time. Mean micro-vibration power is determined. Its deviation from a reference value being equal to or greater than 40%, pathological process is considered to be available in the zone.
EFFECT: high accuracy in determining vestibular dysfunction cases.

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.

SUBSTANCE: invention relates to medical equipment, namely to devices of long-term ECG monitoring. Electrode device for wearable ECG-monitor contains system of on-skin electrodes and monitoring unit, electrically connected to each other and placed on pendant fixed on the body. System of on-skin electrodes consists of two matrices of pin electrodes, whose free butt end parts have salient spherical surface and are installed on belt part of pendant, tightly filling the body with possibility of providing "dry" galvanic contact with areas of chest anterior surface in conditions of patient's free movements. Each matrix consists of two groups, pin electrodes in each of them are galvanically connected to each other. One of the groups, which has larger area, is intended for ECG signal registration, the other, with smaller area, for connection to means of cophasal noise suppression. Butt end fixing parts of electrode pins are fixed on flexible dielectric padding, connected with pendant, made from elastic textile material.
EFFECT: invention makes it possible to increase reliability of galvanic contact between patient's body and system of "dry" electrodes and improve ratio signal/noise of ECG signal in process of long-term application.
