Разработана и исследована методика детектирования R-зубцов электрокардиосигнала на основе применения кратномасштабных вейвлет-преобразований. В предлагаемую методику обнаружения R-зубцов включены последовательные этапы цифровой обработки электрокардиосигнала: кратномасштабное вейвлет-преобразование; набор нелинейных операторов; адаптивный алгоритм обнаружения максимумов сигнала. Проведён сравнительный анализ предлагаемой методики с существующими подходами к обнаружению R-зубцов электрокардиосигнала. Для получения количественных характеристик оценки эффективности обнаружения R-зубцов использовано имитационное моделирование электрокардиосигнала, содержащего шумы и помехи различной интенсивности и природы возникновения. Эффективность рассматриваемых подходов к обнаружению R-зубцов электрокардиосигнала исследована для клинических записей биосигналов. Оценена абсолютная погрешность измерения длительностей RR-интервалов для модельных сигналов с различными уровнями зашумления. Показано, что предложенная методика обнаружения R-зубцов электрокардиосигнала на основе кратномасштабных вейвлет-преобразований характеризуется малыми погрешностями измерения длительностей RR-интервалов, высокими показателями истинного обнаружения и малыми ошибками ложного обнаружения и пропуска.</p></abstract><trans-abstract xml:lang="en"><p>Increasing the efficiency of cardiological diagnostics based on the analysis of human heart rate variability necessitates the development of accurate methods for detecting the R-waves of the electrocardiosignal (ECG signal). A technique for detecting R-waves of an ECG signal based on the wavelet multiresolution analysis (WMRA). The proposed technique for detecting R-waves includes sequential stages of digital processing of an ECG signal: WMRA; a set of nonlinear operators; adaptive algorithm for detecting signal peaks. A comparative analysis of the proposed technique with existing approaches to the detection of R-waves of the ECG signal has been carried out. To obtain quantitative characteristics of evaluating the efficiency of detecting R-waves, we used imitation modeling of an ECG signal containing noises and interferences of various intensity and nature of occurrence. The effectiveness of the considered approaches to the detection of R-waves of the ECG signal was investigated for clinical recordings of ECG signal. The absolute error of measuring the RR-interval durations for model signals with different noise levels is estimated. It is shown that the proposed method for detecting R-waves of an ECG signal based on WMRA is characterized by small errors in measuring the duration of RR-intervals, high rates of true detection and small errors of false detection and omission.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрокардиосигнал</kwd><kwd>R-зубец</kwd><kwd>погрешность</kwd><kwd>детектирование</kwd><kwd>кратномасштабные вейвлетпреобразования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ECG signal</kwd><kwd>R-wave</kwd><kwd>uncertainty</kwd><kwd>detecting</kwd><kwd>multiresolution wavelet transforms</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">Федотов А.
