Показана низкая диагностическая значимость длительности зубца Р и индекса Макруза, рассчитанных общепринятыми методами. Наиболее существенные различия выявлены по минимальной длительности зубца Р, оказавшейся ниже при ФП (в среднем 63,28 и 70,05 мс; р &lt; 0,05), нормированной длительности зубца Р (соответственно - 15, 68 и 29, 50 мс; р &lt; 0,05) и дисперсии зубца Р (51,28 и 42,39 мс; р &lt; 0,01). Кроме этого, для развития ФП оказалось характерным увеличение минимальной и нормированной длительности интервала PQ, а также его дисперсии. При этом данные параметры коррелировали с наличием у больных клинических признаков сердечной недостаточности и, отчасти, стабильной стенокардии. С артериальной гипертензией корреляции отсутствовали. Высказано предположение о новых маркерах нарушений электромеханического сопряжения в миокарде предсердий и их значении в патогенезе развития ФП.</p></abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность</kwd><kwd>стабильная стенокардия</kwd><kwd>фибрилляция предсердий</kwd><kwd>длительность зубца Р и интервала PQ</kwd><kwd>дисперсия зубца Р и интервала PQ</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">Радзевич А.Э., Уранов В.Н.
