FIELD: medicine.
SUBSTANCE: method involves recording rhythmocardiogram. Then, spectral analysis of RR intervalogram components in frequency bandwidth from 0.04 to 0.4 Hz is carried out and information value Z is determined from formula Z=Ahf/Alf, where Ahf is the maximum of high frequency component in bandwidth from 0.14 to 0.4 Hz, Alf is the minimum of high frequency component in bandwidth from 0.04 to 0.14 Hz. Z value being greater than 45 and lower than 14, persons consuming narcotic drugs are detected. Z value being lower than 14, persons consuming sedative drugs like opium, morphine, heroine are detected. Z value being greater than 45, persons consuming psychostimulating drugs like cocaine, amphetamine, efedrone, sydnocarb are detected.
EFFECT: high reliability of screening study data.
