Of all 6630 protocols analyzed, according to 24-hour ECG monitoring, AF paroxysm was detected in 97 people as an accidental finding. These patients were included in the main study group. The control group consisted of 99 patients from the same cohort without paroxysmal AF, having the anthropometric and comorbidity parameters similar to the patients of the main group.</p> <p><bold>Results.</bold> In the absolute majority (97.9%) of patients in the main group in whom paroxysmal AF was detected, a special variant of extrasystole was revealed – early atrial “P on T” type (versus 4.0% in patients in the control group) [OR 8461.648 (382.1983;187336)]. The number of supraventricular single, paired and group extrasystoles was significantly higher in the main group, but the number of ventricular extrasystoles did not differ significantly.</p> <p><bold>Conclusion.</bold> One of the main ECG predictors for the development of paroxysmal AF in asymptomatic patients is the appearance of supraventricular extrasystole of the “P on T” type. In the mechanism of formation of AF paroxysm during supraventricular extrasystole of the “P on T” type, not only electrophysiological mechanisms play a role, but also the heart biomechanics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – изучить особенности ЭКГ-картины по данным суточного мониторирования ЭКГ по Холтеру у пациентов с пароксизмальной фибрилляцией предсердий (ФП) и на основании полученных данных определить основные предикторы развития данного нарушения ритма.</p> <p><bold>Материал и методы. </bold>Проведено одноцентровое исследование по типу кросс-контроля. Из всех проанализированных 6630 протоколов, по данным суточного мониторирования по Холтеру, у 97 человек был выявлен пароксизм ФП как случайная находка. Эти пациенты вошли в основную группу исследования. Группу сравнения составили 99 пациентов без пароксизма ФП из той же когорты, которые по основным антропометрическим показателям и параметрам коморбидности соответствовали основной группе.</p> <p><bold>Результаты. </bold>У абсолютного большинства (97,9%) пациентов основной группы, у которых был выявлен пароксизм ФП, регистрировался особый вариант экстрасистолии – ранней предсердной по типу «P на Т» (против 4,0% у пациентов контрольной группы) [OR 8461.648 (382.1983;187336)]. Также достоверно выше в основной группе было количество наджелудочковых экстрасистол, как одиночных, так и парных, и групповых, количество же желудочковых экстрасистол достоверно не отличалось.</p> <p><bold>Выводы. </bold>Одним из основных ЭКГ-предикторов развития пароксизмальной ФП у бессимптомных пациентов является появление наджелудочковой экстрасистолии по типу «P на T». В механизме формирования пароксизма ФП при наджелудочковой экстрасистолии типа «Р на Т» играют роль не только электрофизиологические механизмы, но и биомеханическая составляющая.</p></trans-abstract><kwd-group xml:lang="en"><kwd>extrasystole</kwd><kwd>predictor of atrial fibrillation</kwd><kwd>atrial extrasystole</kwd><kwd>supraventricular extrasystole</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>экстрасистолия</kwd><kwd>предиктор фибрилляции предсердий</kwd><kwd>предсердная экстрасистолия</kwd><kwd>наджелудочковая экстрасистолия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Nalliah CJ, Sanders P, Kalman JM.
