[Regulatory mechanisms of young men heart rate during psychoemotional load accompanied by irritation with different sounds].

The goal of our research was to evaluate regulatory mechanisms of young men heart rate during psychoemotional load on the background of sound irritations of different characteristics. The study was a community trial and performed by single blind method on volunteer young men (age 18-22, n=73). As a method of description of heart rate regulation mechanisms, analysis of heart rate variability was selected. Psychoemotional load was studied by Landolt rings. We observed that only high frequency sound irritation increases mistakes and reaction time during psychoemotional load. We conclude that despite of initial status of organism regulation mechanisms, during high frequency sound irritation, quality of psychoemotional functions worsens. Increasing of sympathetic effect in persons with initial sympathetic domination in vegetative nervous system is observed.
