Application of Modern Technologies in New Ultra-High Resolution Electrocardiography Method

The present work has been performed using a new method of ultra high resolution instrumental electrophysiology (UHR IEP) based on application of the new advances of the radio electronics as well as radar and information technologies of bioelectric signals processing and expanding of the amplitude and frequency ranges of their studies. One of UHR IEP divisions is new method of ultra-high resolution electrocardiography. The theoretical part included the set of problems solution with application of random processes statistical theory and detection theory. One of the basic problems was development of optimal algorithms of electrocardiosignal (ECS) processing on the background of different kinds of obstacles and noises. This provided the solution of such problems for radio electronic and radar technologies as detection and estimation of ECS components. The specific approaches, methods, algorithmic, program, and hardware means have been developed for detection, recording, and processing of the ECS components with low amplitudes and high frequencies, detection of informative components in them, and their parameters estimation in the presence of noise and obstacles. Hence, the goals of studies are deep analysis of the fine structure of ECS and development of their processing procedures for cardiac pathologies diagnostics, including ischemia at early stages of its progress.
