To estimate probability of atrial fibrillation (AF) recurrence at various methods of sinus rhythm recovery. Material and methods. Patients (n=153) with nonvalvular AF lasting from 24 hours to 6 months were examined. All patients were divided into 3 groups. In group 1 (n=49) sinus rhythm was restored by the drug therapy, in the group 2 (n=57) – by the electrical cardioversion, and in the group 3 (n=47) patients underwent radio-frequency isolation of pulmonary veins. Echocardiography was performed in all patients during AF, and also on the 1, 3, 5, 15 days and in 6 months after sinus rhythm recovery. Results. The absence of AF paroxysms within first 2 weeks after sinus rhythm recovery was a significant predictor of sinus rhythm preservation (р&lt;0.001) and reduction in a number of AF paroxysms р&lt;0.001 during 6 months of follow-up. Emergence of AF paroxysms during the first 2 weeks predicted an increase of their probability within next 6 months (odds ratio=15.37). Significant interrelation between the time of left atrium function restoration (peak A&lt;0.5m/s) and probability of AF paroxysms emergence in early (up to 2 weeks) and late (till 6 months) follow-up periods was also observed (р&lt;0.05). Conclusions. Peak A&gt;0.5 m/s measured by transmitral flow in the first 24 hours after sinus rhythm recovery as well as absence of AF paroxysms within 2 first weeks after sinus rhythm recovery were significant predictors of the sinus rhythm preservation up to 6 months at any type of cardioversion.</p></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Оценить вероятность рецидивов фибрилляции предсердий (ФП) при различных вариантах восстановления синусового ритма. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 153 пациента с неклапанной формой ФП длительностью от 24 ч до 6 мес. Пациенты разделены на 3 группы. Группа 1 (n=49) – синусовый ритм восстановлен с помощью медикаментозной терапии; группа 2 (n=57) – с помощью электроимпульсной терапии; группа 3 (n=47) – при помощи радиочастотной изоляции легочных вен. Всем пациентам проводилось эхокардиографическое исследование на момент ФП, а так же на 1,3,5,15 сут и через 6 мес после восстановления синусового ритма.  Результаты. Во всех группах отсутствие пароксизмов ФП после восстановления синусового ритма в течение первых 2-х нед оказалось значимым предиктором сохранения синусового ритма к 6 мес наблюдения (р&lt;0,001) и снижения количества пароксизмов ФП в течение 6 мес (р&lt;0,001). Появление пароксизмов ФП в течение первых 2-х нед свидетельствовало о повышении их вероятности в течение 6 мес (отношение рисков 15,37). Отмечена достоверная взаимосвязь между сроками восстановления функции левого предсердия (пик А&gt;0,5 м/сек) и вероятностью возникновения пароксизмов ФП в раннем (до 2-х нед) и позднем (до 6 мес) периодах наблюдения (р&lt;0,05). Заключение. Измеренный по трансмитральному потоку пик А&gt;0,5 м/с в 1 сут после восстановления синусового ритма, а также отсутствие пароксизмов ФП в течение первых 2 нед после восстановления синусового ритма явились достоверными предикторами его сохранения сроком до 6 мес при любом способе кардиоверсии. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>тромбоэмболические осложнения</kwd><kwd>кардиоверсия</kwd><kwd>восстановление синусового ритма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>thromboembolic disorders</kwd><kwd>cardioversion</kwd><kwd>sinus rhythm recovery</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">Wann L.S., Curtis A.B., Ellenbogen K.A. et al. 2011 ACCF/AHA/HRS Focused Update on the Management of Patients With Atrial Fibrillation (Update on Dabigatran) A Report of the AmericanCollege of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines.
