Были выделены ключевые признаки, такие как длительность комплекса QRS, интервалы RR и частота сердечных сокращений (ЧСС). Классификация аритмий выполнена на основе данных базы MIT-BIH Arrhythmia Database. Разработаны визуализации и логическая схема для автоматического определения ГЗА. Цель исследования – разработка и валидация алгоритма классификации гемодинамически значимых аритмий, основанного исключительно на электрокардиографических признаках. Предлагаемая методика опирается на ранее опубликованные исследования, посвящённые использованию ЭКГпризнаков в диагностике аритмий, и направлена на повышение доступности диагностики в условиях ограниченных ресурсов. Основная цель работы заключается в расширении доступности диагностики сердечных аритмий посредством интерпретируемых инженерных решений.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents an automated method for the classification of hemodynamically significant arrhythmias (HSA) based solely on electrocardiographic (ECG) features, without the use of additional imaging diagnostic techniques. The proposed approach relies on key ECG parameters, including QRS complex duration, RR intervals, and heart rate (HR). The study is based on data from the open-access MIT-BIH Arrhythmia Database, which contains multiple types of cardiac rhythm disturbances. A comparative analysis of arrhythmia classes was conducted, leading to the identification of diagnostically significant predictors associated with hemodynamic instability. Logical decision rules and a decision tree model were developed to enable automatic recognition of HSA and clinical risk stratification. The proposed algorithm demonstrates high interpretability and practical applicability for real-time monitoring systems. The results confirm that ECG-based features alone can be effectively used for preliminary detection of dangerous arrhythmias. The developed approach is especially valuable for telemedicine systems and healthcare facilities with limited access to expensive diagnostic equipment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ЭКГ</kwd><kwd>аритмия</kwd><kwd>гемодинамически значимая аритмия (ГЗА)</kwd><kwd>комплекс QRS</kwd><kwd>интервалы RR</kwd><kwd>частота сердечных сокращений</kwd><kwd>MIT-BIH</kwd><kwd>автоматическая диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ECG</kwd><kwd>arrhythmia</kwd><kwd>hemodynamically significant arrhythmia (HSA)</kwd><kwd>QRS complex</kwd><kwd>RR intervals</kwd><kwd>heart rate</kwd><kwd>MIT-BIH</kwd><kwd>automated diagnosis</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research was funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. AP25796273).</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">Moody G.B.
