We studied the spatial and temporal relationships of components of the mechanism regulation of rhythmogenesis considering the vegetative status in relative functional rest, as well as physical and mental stress. Spatial characteristics evaluated by the power spectrum of heart rate variability waves of different frequencies. As the timing of the formation of the heart rhythm were used heart rate, the most common cardiac interval (fashion) and scatter the duration of cardiac cycles. At rest, the most prominent link between temporal and spatial characteristics of the formation of the heart rate and its regulation occur in subjects with marked predominance of the central and autonomic autonomic regulation of heart rate, as well as the predominance of sympathetic nervous system activity and the balance between the divisions of the autonomic nervous system. Physical and intellectual stress causes an increase in the space-time characteristics of the contingency mechanism rhythmogenesis regulation of cardiac function.
