Изменения сегмента ST на электрокардиограмме (ЭКГ) могут наблюдаться как у вполне здоровых детей, так и у детей с органической патологией миокарда. В настоящее время отсутствуют рекомендации по ведению педиатрических пациентов с документированными изменениями сегмента ST.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: анализ клинических данных, верификация причин изменений сегмента ST на ЭКГ, определение диагностических и лечебных подходов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование были включены 22 пациента с изменениями сегмента ST и зубца Т по данным стандартной ЭКГ. Медиана возраста на момент госпитализации составила 15 лет. Всем пациентам проведено суточное мониторирование ЭКГ (СМЭКГ), велоэргометрия (ВЭМ), стандартная траснсторакальная эхокардиография (ЭхоКГ), диагностический лабораторный скрининг, который включал определение липидного спектра, анализ электролитов (натрий, калий, кальций), оценку маркеров повреждения и воспаления миокарда. В случае выявления отклонений проводилось дополнительное диагностическое обследование: мультиспиральная компьютерная томография коронарных артерий (МСКТ-коронарография), перфузионная сцинтиграфия миокарда (ПСМ) и стресс-ЭхоКГ. Результаты. Обследованы 22 пациента с изменениями сегмента ST на ЭКГ покоя. В двух случаях причиной изменений сегмента ST была недифференцированная кардиомиопатия. Оба пациента были асимптомными, один из них спортсмен. В восьми случаях изменения сегмента ST и зубца Т на ЭКГ были расценены как проявления вегетативной дисфункции на фоне сопутствующей патологии. Аномалии хода и аномалии развития коронарных артерий, включая мышечные мостики (ММ) и аномалии отхождения коронарных сосудов, были выявлены у 12 обследованных пациентов, в том числе у двух пациентов с синдромом и феноменом Вольфа – Паркинсона – Уайта (WPW) у которых, после радиочастотной аблации (РЧА) дополнительных путей сохранялись изменения сегмента ST, и у трех детей-спортсменов. На основании проведенного обследования одной пациентке с выявленной аномалией коронарных артерий была проведена хирургическая коррекция. Пяти пациентам назначена медикаментозная терапия β-блокаторами.</p></sec><sec><title>Заключение</title><p>Заключение. Изменения сегмента ST на ЭКГ требуют особого внимания. Стандартные ЭКГ и ЭхоКГ имеют ограничения в диагностике аномалий коронарных артерий. Обязательным методом дообследования являются пробы с физической нагрузкой. В случае подозрений на ишемический характер изменений крайне важно исключить аномалии коронарных артерий с помощью дополнительных методов обследования, важнейшим из которых является МСКТ-коронарография. Вспомогательное значение имеют инвазивная коронароангиография, ПСМ, стресс-ЭхоКГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. ST segment changes can be observed both in completely healthy children and in children with organic myocardial pathology. Currently, there are no recommendations for the management of pediatric patients with documented ST segment changes on the ECG.</p></sec><sec><title>Aim</title><p>Aim: To analyze clinical data, identify causes of ST segment changes on the ECG and determine diagnostic algorithms for treatment tactics.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 22 patients with ST segment and T wave changes according to standard ECG. All patients underwent daily ECG monitoring, exercise stress test, standard Echo. Diagnostic laboratory screening included determination of lipid spectrum, electrolyte analysis (sodium, potassium, calcium), assessment of markers of myocardial damage and inflammation. In case of deviations, additionally MSCT coronary angiography, myocardial perfusion scintigraphy and stress echocardiography were performed.</p></sec><sec><title>Results</title><p>Results. 22 patients with ST segment changes on the ECG were examined. In two cases, the cause of ST segment changes was undifferentiated cardiomyopathy. Both patients were asymptomatic, one of them was an athlete. In eight cases, ST segment and T wave changes on the ECG were assessed as manifestations of autonomic dysfunction against the background of concomitant pathology. Anomalies of the course and development of the coronary arteries, including muscular bridges (MB) and anomalies of the origin of the coronary vessels, were detected in 12 examined patients, including two patients with WolffParkinson-White (WPW) syndrome and phenomenon, in whom ST segment changes persisted after radiofrequency ablation (RFA) and in three sportsmen. Based on the examination, one patient with an identified anomaly of the coronary arteries underwent surgical correction. Five patients were prescribed drug therapy with β-blockers.</p></sec><sec><title>Conclusion</title><p>Conclusion. ST segment changes on the ECG require special attention. Standard ECG and echocardiography have limitations in diagnosing coronary artery anomalies. A mandatory method of additional examination is physical exercise tests. In case of suspicion of an ischemic nature of changes, it is extremely important to exclude coronary artery anomalies using additional examination methods, the most important of which is MSCT coronary angiography, invasive coronary angiography, myocardial perfusion scintigraphy, stress echocardiography are of auxiliary importance.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>изменение сегмента ST</kwd><kwd>нарушение реполяризации</kwd><kwd>мышечные мостики и аномалии коронарных артерий</kwd><kwd>МСКТ-коронарография</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ST segment changes</kwd><kwd>repolarization abnormalities</kwd><kwd>muscular bridges</kwd><kwd>coronary artery anomaly</kwd><kwd>MSCT coronary angiography</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">Paech C., Moser J., Dähnert I., Wagner F., Gebauer R.A., Kirsten T. et al.
