Blood pressure rhythm estimation based on shape of patterns for analytic spectra

Abstract

The paper presents the latest results of developing new methods, based on Multiscale Correlation Analysis for bio-medical signals processing. It is shown that in case a signal has the form of repeated wave pulses, MCA naturally leads to the technique previously introduced by the authors and called the analytical spectra. It is also demonstrated, that detecting typical MCA fragments by appropriate patterns, gives the possibility to significantly improve the repetition estimation. The paper discusses the application of these methods to the problems of the blood pressure rhythm monitoring. In relation to monitoring BP some characteristics of the method are under discussion.

• lood pressure monitoring
• third generation sensors
• multiscale correlational analysis
• analytic spectra

Оценивание ритма давления крови по форме аналитического спектра

В настоящей статье обсуждается новые результаты приложений методов многомасштабного корреляционного анализа к сигналам медико-биологического происхождения. Показано, что в случае, когда сигнал содержит повторяющиеся фрагменты импульсного типа, МКА естественно приводит к разработанной ранее авторами технике аналитических спектров. В статье также продемонстрировано, что за счёт подбора формы спектрального окна можно улучшить оценки ритма повторений. Обсуждаемые результаты продемонстрированы на примере задачи мониторинга ритма артериального давления.
