Introduction. The mental activity brain mechanisms are the object of many studies in psychophysiology. The mental activity vegetative providing participation regulation and evaluation problem by the indications of the heart rhythm while processing various information is considered one of the most important tasks.

Purpose. The aim of our study was to find out the heart rhythm vegetative regulation peculiarities while processing different modality information and presentation speed.

Methods. In the experimental study participated 30 men aged 19 to20. The study was held using computer-aided devices «Dіаgnоst1М» and «Cardiolab». In the background and while doing tasks with different presenting information speed on the heart rhythm variability indications different modality registration irritators was held (the average meaning of the HRF, mode (Mo), mode amplitude (AMo), standard deviation of the cardio-intervals massive (SDNN), stress index (SI)).

Result. It has been proved, that while the processing verbal and image information speed growing the heart rhythm regulatory mechanisms activation level gradually increases and decreases on condition of the irritators tempo presentation decrease. When processing information on verbal stimuli at all speeds, the heart rate indicators were somewhat higher than the presentation of figures

Conclusion. It has been found, that the heart rhythm vegetative regulation peculiarities depend on the speed of presenting irritators and do not depend on the signal modality.
