The program is designed for autonomic nervous system (ANS) state evaluating on basis of heart rate variability analysis. It can be additionally used for analysis of the dynamic of the patient's state using ECG recorded in the process of long-term EEG-studies (EEG-videomonitoring, ambulatory monitoring, neuromonitoring, PSG-studies as a result of pharmacotherapy, physical and psycho-emotional stresses, and also for controlling the treatment effectiveness. It allows to detect the dysfunctions of ANS during sleep and wakefulness.

Special screening tests carrying out during functional tests or long-term monitoring are available. Such tests allow to characterize initial vegetative tone, vegetative reactivity and vegetative support of patient vital activity. Resulting diagnostic estimation is made on the basis of index of regulatory systems adequacy
