Purpose — present parameters estimation of vegetative balance and activity of regulatory systems of pregnant women in view of their psychoemotional state.

Patients and methods. A total of 168 pregnant women were examined in ІІ and ІІІ trimesters (26.80±0.73). Psychoemotional state was investigated by means of Spielberger-Khanin Anxiety Scale with estimation of state and trait anxiety. The research groups were divided according to the level of state anxiety. The 1st group included 20 pregnant women with high level of state anxiety. The ІІnd group was presented by 114 pregnant women with medium level of state anxiety. The ІІІrd group included 34 pregnant women with anxiety level of 30 points and less that characterizes low level of state anxiety. Analysis of heart rate variability of pregnant woman was performed according to the 5-minute record of cardiointervalogramm using cardiographic system CardioLab, manufactured by KHAI-MEDICA (Kharkiv, Ukraine). Estimation of basic parameters was made according to working group of European Heart Rhythm Association recommendations.

Results and conclusions. Based on the performed research of heart rate variability of pregnant women with regard to state anxiety level there was determined the suppression of parasympathetic regulation, which promoted the increase of sympathetic influence on heart rate of pregnant women with high and medium state anxiety levels comparing to pregnant women with low state anxiety level. Thus, it was determined that with the increase of state anxiety level the indicators, depending on parasympathetic regulation, decreased, and those, depending on sympathetic regulation, increased. These changes indicate the vegetative homeostasis disorder in conditions of the increase of anxiety level and the prevalence of neurohumoral influence on heart rate regulation can indicate an attempt to compensate the imperfection of adaptation processes in this group of women.

Key words: pregnancy, psychoemotional state, anxiety, heart rate variability, сardiointervalography.
