В работе проведен краткий обзор метода электрокардиографии, определены основные характеристики артефактов и паразитных сигналов, которые возникают при использовании данного метода. По результатам анализа проведено моделирование цифрового генератора зашумленного электрокардиографического сигнала, с возможностью изменения основных параметров сигнала и помех. Предложены варианты использования данной модели в учебном процессе, при анализе реальных схемных решений и алгоритмов обработки электрокардиографических сигналов.
This paper gives a brief review of the method of electrocardiography (ECG), the basic characteristics of artifacts and spurious signals that occur when using this method. According to the analysis of simulated digital generator noisy ECG signal with the possibility of changes in the basic parameters of the signal. The developed model allows the generation of noisy ECG signal with the ability to set the parameters of ECG signal and the levels of the main types of interference in the real limits. In this model, instead of the standard form of the ECG signal was used only a portion there of - QRS-complex, which determines the amplitude and frequency parameters of the electrocardiographic signal. Realized generator noisy ECG signal allows to assess the effectiveness of various methods of noise suppression, thus can be used as a learning process and the development of real devices. The developed model allows you to check the stability of different algorithms to synchronize devices with the rhythm of the ECG signal that can be used when designing devices biosynchronization and biofeedback.
