Nonlinear dynamics of a simple mathematical model of neural control of the heart rate variability taking into account the external influences simulating stressful loadings is investigated by methods of computer experiment. Spectral power density of processes and autocorrelation function are calculated and the time of decreasing of autocorrelation function and time of relaxation of the system are estimated to analyze the behavior of the system and to compare the results of simulation with the real data.
