Abstract: 

In this work ап approach to study multimode regimes of dynamics of biological systems is proposed that is based оп the quantitative description of complexity of instantaneous frequencies for different rhythms. In experiments on white rats it is shown that stress does not result in strong changes of complexity measures of evolutionary dynamics in the low-frequency region of heart rate variability. However, changes of the dynamics in the high-frequency region take place and there are differences in reactions to stress in female and male rats.
