The article considers the system of computer analysis of ECG and the software implementation of this system. The system provides for automatic recognition of singular points of ECG and automatic detection of ECG characteristic areas. In the design and implementation of the system there were widely used the finite automata. This allowed to visualize the logic of the system, to avoid design errors and to accelerate the process of creating the system.The analysis of test results developed by the team of the prototype of the computerized ECG analysis system with the advanced capabilities of automated search for characteristic sites allows us to conclude that the reliability of ECG interpretation by a specialist increases with a substantial reduction in the time required to perform this procedure. This positive effect is achieved through the implementation of the procedure for automatic recognition of special ECG points and the use of automated means of searching for ECG lines. The system increases the reliability of decoding ECG by a doctor-cardiologist for the purpose of diagnosis and significantly reduces the time to perform this procedure.
Application of simulation techniques in modern educational process associated with the use of virtual simulators in medical education is topical issue in article examined. Literary review of using simulations in medical education was purpose of this article. Material and methods. Keywords used in search simulation technologies, simulators, medical education (in Russian and English), using Google Scholar search system, search range from 2009 to 2019. More than 19 000 articles is founded, using sorting by date and exact matches, and we narrowed down the search result to 98 articles that we analyzed, selected 32 of them, taking into account the purpose of the article. Results. It has identified the main advantages of using simulators, which allow the medical student to present the object of study and perform practical actions with it. Simulators independently set the initial parameters of the conducted research and register the corresponding changes in the experimental results, analyze, identify patterns and draw conclusions, if necessary, repeatedly repeating attempts. It also shows the difficulties associated with significant initial costs for teacher’s training, and the lack of current educational modeling programs. Conclusion. The use of computer simulation technology in the educational process increases the objectivity and quality of the verification and assessment of knowledge, skills and possessions of practical skills of students, and in clinical practice can improve the skill level of practitioners.
В работе рассматриваются модели потоков данных и этапы цифровой обработки сигналов в мобильном устройстве оперативного определения жизнеугрожающих состояний сердечно-сосудистой системы. Устройство считывает сигналы ЭКГ пациента и анализирует различные виды аритмий сердца. При обнаружении жизнеугрожающего состояния устройство формирует сообщение пациенту и передает данные ЭКГ на компьютер врача. Особенностью данного устройства является его персонификация и применение надежного выявления комплексов QRS за счет использования алгоритма анализа формы сигнала, основанного на методе Dynamic time warping. Благодарности: работа выполнена при финансовой поддержке гранта РФФИ, проект № 18-413-310002
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
