В системах удаленного мониторинга продолжительность непрерывной работы определяется возможностями носимых пациентом устройств. Они предназначены для съема и регистрации комплекса биомедицинских сигналов, предварительной обработки и анализа сигналов и данных.Цель настоящей статьи – разработка алгоритма интеллектуального мониторинга состояния здоровья. Он обеспечивает эффективное использование вычислительных и энергетических ресурсов носимых устройств пациента, снижение тока потребления, увеличение автономности его работы. Для решения проблемы используется методология теории интеллектуальных измерений. Она заключается в изменении интеллектуальным элементом системы количества используемых измерительных каналов, методов и алгоритмов измерений и обработки сигналов в зависимости от изменения состояния объекта измерений.Для реализации алгоритма интеллектуального мониторинга состояния здоровья система должна иметь многоуровневую структуру. Носимая система должна состоять из устройства пациента, предназначенного для регистрации комплекса биомедицинских сигналов, и носимого компьютера пациента, предназначенного для обработки и анализа сигналов, контроля текущего состояния пациента. Алгоритм интеллектуального мониторинга заключается в следующем. Фоновый режим устанавливается, когда состояние пациента соответствует состоянию нормы. В этом режиме оцениваются не более двух показателей, наиболее значимых для диагностики, и контролируется состояние нормы. Режим активного мониторинга устанавливается, когда контролируемые в фоновом режиме параметры выходят за границы нормы. В этом режиме активируются дополнительные каналы регистрации биомедицинских сигналов, оценивается расширенный комплекс значимых для диагностики показателей. Экспериментальная апробация системы и алгоритма интеллектуального мониторинга была проведена с использованием системы удаленного мониторинга сердечного ритма и эпизодов фибрилляции предсердий. Результаты апробации показали целесообразность и эффективность использования предложенной структуры и алгоритма мониторинга.</p></abstract><trans-abstract xml:lang="en"><p>Continuous and steady running of health status remote monitoring systems is essential not to omit episodes of acute exacerbation of chronic disease. Running time of such systems is largely determined by performance capabilities of the patient's wearable system elements. To ensure its long-term operation and efficient performance, the monitoring system must have multilayered structure with the elements realizing recording and picking off biomedical signals, signal processing and analysis, estimation of patient current condition, dynamics of the disease and its prognosis. For this purpose, it is necessary to use smart monitoring algorithms. A specific feature of such algorithms is change of the number of channels used for biomedical signal recording and processing according to the change of patient’s condition. To detect the exacerbation first symptoms by means of the patient's wearable computer, additional channels are activated for recording biomedical signals used to evaluate the expanded complex of diagnostically significant parameters of the disease and their integration when specifying the patient's condition. The system and intelligent monitoring algorithm is tested with the use of heart rate remote control and atrial fibrillation episode detection system. The testing results of the developed system and algorithm are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>система</kwd><kwd>удаленный мониторинг</kwd><kwd>состояние здоровья</kwd><kwd>обработки и анализ</kwd><kwd>биомедицинские сигналы</kwd><kwd>алгоритм</kwd><kwd>интеллектуальный мониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>system</kwd><kwd>remote monitoring</kwd><kwd>health status</kwd><kwd>processing and analysis</kwd><kwd>biomedical signals</kwd><kwd>algorithm</kwd><kwd>intelligent monitoring</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке РФФИ, гранты No 16-07-00599 "Модели, методы и система интеллектуального телемедицинского мониторинга состояния здоровья человека и прогнозирования обострения заболеваний" и No 18-29-02036 "Разработка новых алгоритмов автоматического распознавания опасных нарушений сердечного ритма по поверхностной и инвазивной электрокардиограмме".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Long-Term Cardiovascular Outcomes in Men with Obstructive Sleep Apnoea-Hypopnoea with or Without Treatment with Continuous Positive Airway Pressure: an Observational Study / J.
