NEW METHODS FOR STUDYING STATISTICAL STABILITY OF CARDIOINTERVALS
According to the Eskov - Zinchenko effect in the form of statistical instability of samples of any parameters of body functions, the problem of statistical stability of the parameters of pseudo - attractors arises, which describe the same physiological state of one subject. The research purpose was to prove a statistical instability in cardio interval samples. Materials and methods. We studied a group of women (average age 29 years) according to the parameters of the cardiovascular system. In order to check the statistical stability of a group of 15 subjects, the series of tests were carried out (registration of samples of cardio intervals) 15 times of registration of these samples in each series using the «Е1ох-01» apparatus. Results. The pseudoattractors present the physiological state of human body. We research parameters of cardiointervals samples of 15-th different people with stable state of their cardio - respiratory systems. We registrated 225 samples of such cardiointervals for every man and calculated 225 square of it pseudoattractors. For such 15-th series (each consists of 15 samples with 300 cardiointervals) we calculated special matrix pare comparison of pseudoattractors square S. For the matrix we calculated number k of such pare when Wilcoxon parameter p>0,05 (such pare have common general distribution). As a result for all such 15-th matrix (for every man) we calculated the number k. We prove that number k for all such matrix move them 90% of all 105 such pare for every matrix. Conclusion. A change in physiological status leads to significant changes in the parameters of pseudoattractors. The area of the pseudoattractor can act as an invariant measure in the study of various static states of the functional systems of the human body.
