Spatial end temporal parameters of various contoursof regulation heart rate and rhythm
Among physiological systems with a clear manifestation of the space-time unity a special place takes the relationship of the structural and chrono-physiological parameters of rhythm formation process of the heart. The aim of this study was to analyze the spatio-temporal relationship of mechanisms of regulation of heart rate and rhythm in relative functional rest. Space-time continuum of rhythmogenesis of heart was evaluated by heart rate variability. Heart rate and rhythm on one side, and the central and autonomous contours of regulatory mechanisms on other side, forms space-time continuum of regulatory system of rhythm-formation function of heart. Different types of heart rhythm regulation corresponds to a certain degree of correlation relationships between the spatial and temporal parameters of frequency shaping and heart rate. In terms of relative functional rest are closer correlation between the structural components are formed of cardiac rhythm, such as the total power of the high (r=0.7), low frequency (r=0.7), very low frequency (r=0.7) spectral components of variability heart rate in absolute terms and scatter maximum and minimum values of cardio. At rest, the most extensive and close relationship between temporal and spatial characteristics of the system of regulation of heart rate occur in subjects with marked predominance of central and independent regulation of cardiac rhythm loops.
