Lytvynenko T.A. Development of an information system for processing cardio signals.

Specialty 8.050101 “Information management systems and technologies” Ternopil Ivan Puluj National Technical University. Ternopil, 2016. This Master’s thesis deals with the methods of processing electro-cardio signals; in particular, the method of electrocardiograms that is based on the statistics approach to the diagnostics of the cardiovascular system by the means of a computer. For the primary methods of processing, the digital filter for eliminating network disturbance (50 Hz) has been calculated and justified. A new method of extracting the trend from an electro-cardio signal was introduced. Considering the zone structure of cardio signals a method of determining diagnostically important zones of electro-cardio signals was introduced. The thesis contains algorithms and methods on modeling cardio signals that were made possible based on the applied stochastic model. Based on the described model and algorithms of cardio signals a system of computer programs was developed for the analysis of registered electro-cardio signals and conducting computer experiments on modeling cardio signals of different classes: electric, magnetic and acoustic nature. Described methods and programs can be used as components of a diagnostic complex for conducting computer experiments on modeling and processing cardio-signals in cardiology research departments. In a way, by modernizing previously developed programs, it is possible to construct a diagnostic complex with the means of a computer for conducting functional diagnostics of the heart condition according to the described method of cardio signal processing.
