In this case, the traditional method is the analysis of Poincare Plots, as well as visualization of various components of heart rate variability. Recently, attempts to relate the change in heart rate dynamics (acceleration and deceleration) to the presence of hidden pathologies of the cardiovascular system. Along with traditional methods, much attention is paid to the search and study of parameters that describe the nonlinear dynamics of the processes of heart rhythm formation. Among these characteristics, the degree of asymmetry of the geometrically interpreted parameters of cardiac activity. The asymmetry dynamics can be determined by the parameters of the Poincare Plot. Previously, the authors proposed a method for determining the state of cardiac activity, based on the use of the so-called “Speed Spot” - a geometric interpretation of the function of changing the heart rhythm and its derivative. This work is a continuation of the study of the informative parameters of “Speed Spot” and is devoted to the analysis of their asymmetry, as well as a comparative assessment of this approach with existing methods for the analysis of the asymmetry of Poincare's spots.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127582720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantages and features of this approach on the system of multilevel description of the working process are determined. It has been determined that the choice of the most effective model is influenced by the design stage of the water passage and the tasks that are set before designer. The general structure of the mathematical description using dimensionless coefficients for the turbine and pumping modes of operation of a reversible hydraulic machine is presented as a block diagram. Calculations of the main parameters of the pump-turbine for a head of 200 m were carried out. The kinematic characteristics (flow angles of the blade system) in the turbine mode and the hydraulic efficiency in the pumping and turbine modes were determined during these calculations. The mathematical model was applied to the kinematic description of the working process during determining the flow angels. According to the calculation results, the isolines of the angles at the optimal point have acceptable values. The values of the hydraulic efficiency at the optimal point of operation in pumping and turbine modes, obtained as a result of calculations, showed good convergence with the experimental data (0.1 % and 0.7 %, respectively). This indicates the correctness of the calculations performed using this approach.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130334843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When considering models of heart rhythm management, at least two main levels can be distinguished: intra- and extracardiac. Each of these levels can also be divided into several sublevels. Intracardiac effects that regulate heart rate include the myogenic, intercellular, intracardiac nervous system and the effects of intracardiac humoral factors (produced in the heart itself). Extracardiac effects include neuroreflex and general humoral regulation of cardiac activity. Probabilistic models of the processes of cardiac activity are mainly used to describe heart rate variability at an extracardiac level. At the same time, probabilistic models were practically not used for the processes underlying the automatism of the heart at the intracardiac level. A probabilistic model of heart rate dynamics is proposed based on the concept of heart contraction because of the influence of many hierarchical random events. The results of the probabilistic modeling presented in the work are in good agreement with the well-known bioelectric models that describe the dynamics of intracardiac activity and make it possible to use a sequence of RR durations (for example, a rhythmogram and a pulsogram) to detect various latent cardiac abnormalities, in particular, atrial fibrillation.","PeriodicalId":115140,"journal":{"name":"2020 IEEE KhPI Week on Advanced Technology (KhPIWeek)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116913522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
