Желудочковые экстрасистолии различной градации были выявлены у 25%. Синусовая тахикардия, не связанная с физической нагрузкой, отмечалась у 40% пациентов, а синусовая брадикардия у 30%. Атриовентрикулярная блокада 1 степени была диагностирована у 45% педиатрических пациентов, различные варианты синоатриальной блокады (неполная и полная) в сумме были выявлены у 30% детей. Миграция водителя ритма по предсердиям, зафиксированная у 50% обследованных. Регистрируются изменения процессов реполяризации: удлинение интервала QT зафиксировано у 45%, синдром ранней реполяризации желудочков выявлен у 75% обследованных. Прямым подтверждением наличия вегетативной дисфункции, явилось снижение вариабельности сердечного ритма (ВСР), низкая и очень низкая ВСР, которая отмечалась у 30% и 10% обследованных детей соответственно.</p></sec><sec><title>Заключение</title><p>Заключение: сердечно-сосудистые осложнения у детей, перенесших COVID-19, представляют собой основную и многогранную проблему. Отмечается широкий спектр нарушений ритма и проводимости сердца, в том числе изменений процессов реполяризации у педиатрической когорты пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><p>To study the impact of SARS-CoV-2 on the cardiovascular system in children and adolescents who have had mild to moderate illness, to identify the characteristics of cardiac rhythm and conduction disturbances in the post-COVID period, and to analyze current literature on the stated issue.</p><sec><title>Materials and methods</title><p>Materials and methods. Electrocardiography and Holter monitoring of ECG in 54 children 3 months after discharge, in the age interval from 1 month to the onset of adulthood, who had a new coronavirus infection of mild or moderate severity.</p></sec><sec><title>Results</title><p>Results. Supraventricular extrasystoles were recorded in 65% of children. Ventricular extrasystoles of various grades were detected in 25%. Sinus tachycardia, not associated with physical activity, was observed in 40% of patients, and sinus bradycardia in 30%. Atrioventricular block of grade 1 was diagnosed in 45% of patients of the pediatric profile, various variants of the sinoatrial block (incomplete and complete) in total were identified in 30% of patients. Migration of the rhythm driver in the atria, recorded in 50% of the examined. Changes in the repolarization processes are recorded: QT interval prolongation was recorded in 45%, the syndrome of early ventricular repolarization was identified in 75% of the examined. A decrease in heart rate variability (HRV) was a direct confirmation of the presence of autonomic dysfunction, and low and very low HRV was observed in 30% and 10% of the examined children, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion. Cardiovascular complications in children who have recovered from COVID-19 are a major and multifaceted problem. There is a wide range of cardiac rhythm and conduction disorders, including changes in repolarization processes, in the pediatric patient cohort.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>новая коронавирусная инфекция</kwd><kwd>сердечно-сосудистая система</kwd><kwd>постковид</kwd><kwd>аритмии</kwd><kwd>процессы реполяризации</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>new coronavirus infection</kwd><kwd>cardiovascular system</kwd><kwd>post-COVID</kwd><kwd>arrhythmias</kwd><kwd>repolarization processes</kwd><kwd>children</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">Zoumpourlis V, Goulielmaki M, Rizos E, Baliou S, Spandidos DA.
