В случае использования нескольких отведений электрокардиосигнала миографическая помеха в разной степени оказывает влияние на каждое из отведений. Это влияние может быть учтено при построении алгоритмов обработки многоканальных записей электрокардиосигнала. Однако в существующей литературе недостаточно полно исследован анализ взаимосвязей отсчетов миографической помехи в различных отведениях электрокардиосигнала. Цель работы – эмпирическое исследование статистических характеристик миографической помехи, выделенной из зашумленных фрагментов электрокардиосигнала. Предложен метод выделения миографической помехи из записей электрокардиосигнала. Метод основан на полиномиальной аппроксимации фрагментов электрокардиосигнала в скользящем окне с последующим весовым усреднением перекрывающихся фрагментов. С использованием данного метода из многоканальных записей электрокардиосигнала были выделены фрагменты миографической помехи. На основе выделенных фрагментов подобрано совместное распределение отсчетов миографической помехи в двух смежных отведениях, а также исследованы корреляционные взаимосвязи между отсчетами миографической помехи в различных отведениях электрокардиосигнала. В результате установлено, что совместное распределение отсчетов миографической помехи в двух смежных отведениях в первом приближении может быть описано с помощью двумерного нормального закона. Кроме того, между отсчетами миографической помехи из двух смежных отведений могут наблюдаться довольно сильные корреляционные взаимосвязи.</p></abstract><trans-abstract xml:lang="en"><p>Electromyographic noise is one of the most common noises in electrocardiogram. In case of several electrocardiogram leads, electromyographic noise affects each lead to different extent. It can be taken into account when developing algorithms for multilead electrocardiogram record processing. However, in the existing literature, there is no information about the relationship of electromyographic noise in various ECG leads and their joint probability distribution. The purpose of this paper is to study statistical characteristics of electromyographic noise in ECG signal, from which the electromyographic noise is extracted. The paper proposes a method for extracting electromyographic noise from electrocardiogram signal, based on a polynomial approximation of electrocardiogram signal fragments in sliding window with overlapping fragment subsequent weight averaging. Using this method, fragments of electromyographic noise are extracted from multichannel electrocardiogram records. Based on the obtained data, a joint probability distribution function of electromyographic noise in two adjacent leads is selected, and the correlation relationships between the electromyographic noise in various ECG leads are investigated. The results show that the joint probability distribution function of electromyographic noise in two adjacent leads in the first approximation can be described using bivariate normal distribution. In addition, between the samples of electromyographic noise from two adjacent leads quite strong correlation relationships can be observed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрокардиосигнал</kwd><kwd>миографическая помеха</kwd><kwd>коэффициент корреляции</kwd><kwd>коррелированный шум</kwd><kwd>длительное мониторирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ECG signal</kwd><kwd>electromyographic noise</kwd><kwd>correlation coefficient</kwd><kwd>correlated noise</kwd><kwd>long-term ECG monitoring</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Нифонтов Е.
