FIELD: medicine.
SUBSTANCE: device for registering biological potentials of fetus' heart has abdominal electrodes, buffer cascades, differential amplifiers, registrar. Maternal electrocardiogram R-tooth time selector is introduced into the device as well as controller, voltage divider with controlled division factor. Biological potentials of fetus' heart can be compensated due to compensation of biological potentials of mother's heart.
EFFECT: improved noise immunity; improved truth of operation.
