Распространенность приступов потери сознания у школьников по результатам исследования «ЭПИЗОД» (Эпидемиология Приступов потерИ соЗнания у детей и пОДростков в России) составила 4,2%, однако по данным только анкетирования не всегда удается исключить кардиальный генез синкопе.</p></sec><sec><title>Цель</title><p>Цель. Провести углубленное обследование детей, подростков и лиц молодого возраста с синкопальными состояниями и выявить изменения лабораторно-инструментальных показателей функционирования сердечно-сосудистой системы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. После анкетирования 1 685 человек 6–22 лет (средний возраст 14 ± 4,4) отобрано 519 (30,8%): 112 (6,6%) – с синкопе и 397 (23,5%) – с пресинкопе. Всем проведен осмотр с измерением роста, веса, артериального давления (АД) и электрокардиографии (ЭКГ) в положении лежа, эхокардиография (ЭхоКГ) с расчетом индекса массы миокарда, холтеровское мониторирование (ХМ), определение уровня К, Mg, Ca, Hb, ферритина.</p></sec><sec><title>Результаты</title><p>Результаты. Распространенность синкопальных состояний в возрасте 6–22 лет составила 6,6%. Отмечены достоверно более низкие значения АД и ЧСС по результатам ХМ в группе с синкопе, более высокие значения интервала QTс на ЭКГ. Выявлена прямая зависимость между продолжительностью интервала QT и задней стенкой левого желудочка (ЗСЛЖд) (r = 0,322, р &lt; 0,001), толщиной межжелудочковой перегородки (МЖПд) (r = 0,334, р &lt; 0,001) и индексом массы миокарда левого желудочка (ИММЛЖ) (r = 0,454, р &lt; 0,001) и отрицательная – с уровнем Ca и Mg (r = –0,341–0,354, р &lt; 0,001).</p></sec><sec><title>Выводы</title><p>Выводы. Распространенность синкопальных состояний среди молодых лиц 6–22 лет оставляет 6,6%. Для молодых лиц с синкопе характерны более низкие значения АД и ЧСС по результатам ХМ и большая продолжительность интервала QTс на ЭКГ. Отмечена прямая зависимость между величиной интервала QT и размерами ЗСЛЖд, МЖПд, ИММЛЖ и отрицательная – с уровнем Ca и Mg.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To conduct an examination of adolescent children and young people with syncope and identify the changes of laboratory and instrumental indicators of the functioning of the cardiovascular system.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. After a survey of 1685 people aged 6–22 years (average age 14 ± 4.4), we selected 519 (30.8%): 112 (6.6%) with syncope and 397 (23.5%) with presyncope. All of them were examined with measurements of height, weight, blood pressure and ECG in the supine position, ECHO with calculation of the myocardial mass index, ambulatory monitoring (AM), level of K, Mg, Ca, Hb, ferritin.</p></sec><sec><title>Results</title><p>Results. The prevalence of syncope at the age of 6–22 years was 6.6%. There were significantly lower blood pressure and heart rate values by AM in the group with syncope, higher values of the QT interval on the ECG. The direct relationship was revealed between the duration of the QT interval and wall thickness LV (r = 0.322, p &lt; 0.001), IVSd (r = 0.334, p &lt; 0.001) and IMMLV (r = 0.454, p &lt; 0.001) and a negative relationship with the level of Ca and Mg (r = –0.341–0.354, p &lt; 0.001).</p></sec><sec><title>Conclusions</title><p>Conclusions. The prevalence of syncope among young people aged 6–22 years is 6.6%. Young people with syncope are characterized by lower blood pressure and heart rate according to the results of AM and a longer duration of the QT interval on the ECG. A direct relationship was noted between QT interval and the size of the LVPWd, the IVSd and the IMMLV, and a negative relationship with the level of Ca and Mg.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>обмороки</kwd><kwd>интервал QT</kwd><kwd>синкопе</kwd><kwd>школьники</kwd><kwd>молодые лица</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fainting</kwd><kwd>QT interval</kwd><kwd>syncope</kwd><kwd>schoolchildren</kwd><kwd>young people</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">Терещенко С.
