Abstract: 

Synchronization between the processes of vegetative regulation of the heart rate and blood pressure in the vessels of microcirculatory channel having in humans a fundamental frequency of about 0.1 Hz is studied. A method for quantitative estimation of the degree of synchronization between these processes is proposed. The method is based on the calculation of a summary percent of phase synchronization of oscillations. A statistical significance of the calculated coefficient of synchronization is analyzed.
