The analysis of the results of heart rate variability of obese patients living in St. Petersburg and the city of Surgut has been undertaken. It revealed an imbalance in the regulation of the autonomic nervous system, with a predominance of sympathicotonia, in obese patients living in the city of Surgut. The analysis of heart rate variability was also performed using the multivariate bioinformatic analysis of multidimensional phase spaces, which determined the evidence base for integrative indicator of the quality (quantitative measure) and markers (diagnostic criteria) of regional differences in the regulation of autonomic disorders of the heart. As based on a systematic approach, the analysis has revealed a decrease of phase space in patients living in the city of Surgut, which indicates a narrowing adaptive potential of the patients. Ranking the diagnostic performance characteristics of heart rate variability in patients with obesity ensured the fi nal set of identifi ers of regional differences of vegetative regulation of heart rate – Total P (mc2) (the total spectral power of heart rate variability), VLF (mc2) (the spectral power of heart rate variability in the range of ultra-low frequencies ), LF (mc2) (the spectral power of heart rate variability at low frequencies).
