Abstract
Objective. The aim of this work was to examine influence of the geomagnetic storms on the hemodynamic parameters and heart rate variability in normotensive rats.
Design and methods. Studies were conducted in Wistar male rats. Registration of systolic blood pressure, beat-to-beat interval and components of heart rate variability were conducted in the days of the geomagnetic storm and in the days, when the Earth’s magnetic field was calm.
Results. We found that, in the days of geomagnetic disturbances sympathetic component of spectrum of heart rate variability decreased, simultaneously we observed a tendency to increase of blood pressure and average of heart rate.
Conclusions. We have suggested, that decline in activity of the sympathetic nervous system contributes to maintain of a normal level of hemodynamic constants during geomagnetic storm.
