The problem of selecting a homogeneous group of subjects can be addressed by calculating the coefficient of variation or by using the ABC method. However, this is not sufficient for homeostatic systems. The aim of the study is to establish the statistical and chaotic patterns of parameters of the cardiovascular system among girls in the city of Surgut following North-South travel. Methods: The data on indicators of the cardiovascular system (CVS) of girls were collected using pulsoximeter EL0X-01. The obtained samples of cardiointervals (CI) were processed as matrices of pairwise comparisons of samples. Results. After two weeks of rest in the South of the Russia, the number of k pairs of samples in the matrices of pairwise comparisons decreases indicating changers towards increased heterogeneity in the CVS parameters. In general, with statistical paired comparison of samples of CI in the group of girls, only 2-15 % of pairs of samples can be attributed to one general population. The calculation of the pairwise comparison matrix of samples of CI for one subject showed that the samples with repeated measurements in the same homeostasis may statistically less match than in a group of different people. Conclusions. Traditional statistics in the description of the CVS has low efficiency, the behavior of the CI is chaotic, because the forecast of dynamics based on the analysis of previous states and the initial value x(t0) is impossible. In the work within the framework of the new approach from the standpoint of the theory of chaos-self-organization, the features of the parameters of the CVS of girls under the action of various climatogeographic factors are studied
