We carry out the analysis on time series of the previously proposed mathematical model of the human cardiovascular system. Directed coupling estimations are analyzed via instantaneous phases modelling of the 0.1 Hz oscillations in heart rate variability and photoplethysmogram, reflecting the activity of the subsystems regulating blood circulation, at various levels of phase noise. The results of the analysis of the model signals are compared with the results of the analysis of experimental signals.","PeriodicalId":164423,"journal":{"name":"Cardio-IT","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132656039","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}

Material and Methods — This study included 127 synchronous records of cardiointervalograms and photoplethysmograms from patients with AH (aged 39-55 years) and 40 records from healthy subjects (aged 20-40 years). Synchronization of the LF rhythms was estimated by calculating the total percentage of phase synchronization, the phase increment correlation, the prediction error, and the phase coherence index. Results — It is revealed that the average values of time delays in communication between studied contours are somewhat lower in healthy people than in patients with AH. At the same time, the strength of this interaction is approximately similar in both studied groups. Conclusion — Patients with AH are characterized by a greater delay in the relationship between LF rhythms in regulation of heart rate and peripheral blood flow, relatively healthy individuals.","PeriodicalId":164423,"journal":{"name":"Cardio-IT","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128077161","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}
