Bekler T. Mathematical models and software tools for synthesis of artificial electrocardiograms

The thesis is devoted to solution of actual problem of assessment quality improvement of algorithms of processing and analysis of electrocardiograms (ECG), built-in digital electrocardiographs, with using of artificial realistic-form signals with internal and external distortions. Original mathematical models for synthesis of artificial ECG, based on independent random parameters distortions of particular fragments of etalon cycle generated by the analytical expression are developed. Models allow to generate realistic-form signals, including those that rarely observed in real life. Testing method of processing algorithms of ECG and checking of characteristics of digital electrocardiographs, which integrates existing approaches to testing and involves using of real and model ECG as test signals is improved. Software tools that implement of proposed models and integrated into program-technical complex for testing of processing algorithms of ECG are developed. The adequacy of developed models and the effectiveness of software tools are confirmed by model experiments.
