Одной из причин внезапной сердечной смерти детей являются наследственные аритмии. С учетом связи повышения температуры тела с манифестацией некоторых наследственных нарушений сердечного ритма (включая типичные электрокардиографические изменения) проведен анализ частоты наследственных нарушений ритма сердца у детей с инфекционными заболеваниями.</p><p>Актуальность исследования обусловлена необходимостью своевременной диагностики наследственных нарушений ритма сердца и проводимости у детей с целью профилактики у них внезапной сердечной смерти.</p><p>Цель настоящего исследования: определить частоту наследственных нарушений ритма сердца у детей с инфекционными заболеваниями на основании клинико-электрокардиографического анализа.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: проведен анализ 3584 электрокардиограмм детей (средний возраст 8,5 ± 5,3 лет, из них мальчики составляли 57,5%, девочки – 42,5%), госпитализированных в Федеральное государственное бюджетное учреждение «Детский научно-клинический центр инфекционных болезней Федерального медико-биологического агентства». При выявлении изменений, характерных для наследственных аритмий, проводилось обследование в зависимости от предполагаемого диагноза (суточное Холтеровское мониторирование ЭКГ, велоэргометрия, эхокардиография). Также уточнялся семейный анамнез, анализировались ЭКГ родителей. Диагноз устанавливался на основании общепринятых диагностических критериев.</p><p>Результаты исследования и заключение. Изменения электрокардиограммы, характерные для синдрома Бругада (I тип), впервые были выявлены у двух детей (0,05%), синдром удлиненного интервала QT диагностирован также у двух пациентов (0,05%). При проведении молекулярно-генетического исследования были идентифицированы мутации в генах SCN5A, KCNQ1. У одной девочки 5 лет с атриовентрикулярной блокадой I степени, гипоадаптацией интервала QT ночью при повторном проведении Холтеровского мониторирования электрокардиограммы в период сна зарегистрирован эпизод мономорфной желудочковой тахикардии. Случаи жизнеугрожающих желудочковых аритмий ранее были описаны в литературе у пациентов с синдромом Бругада. Повышение температуры тела приводит к нарушению работы ионных натриевых каналов, лежащих в основе развития вышеуказанного синдрома, тем самым, с одной стороны, повышая риск развития жизнеугрожающих аритмий и внезапной сердечной смерти, с другой стороны, приводя к клинической манифестации заболевания, позволяя вовремя поставить диагноз. В случае наследственного синдрома удлиненного интервала QT в нашем исследовании увеличение корригированного интервала QT (QTc), скорее всего, обусловлено не прямым влиянием повышения температуры тела на ионные каналы, а изменением (повышением) частоты сердечных сокращений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. One of the causes of sudden cardiac death in children is inherited arrhythmias. In view of the links between the increase in body temperature and the manifestation of some inherited cardiac arrhythmias (including typical electrocardiographic changes), the frequency of inherited cardiac arrhythmias in children with infectious diseases have been analyzed.</p><p>The relevance of the study: is initiated by the necessity of timely diagnosis of inherited cardiac arrhythmias and conduction in children in order to prevent sudden cardiac death in them.</p></sec><sec><title>The purpose of the study</title><p>The purpose of the study: to determine the frequency of inherited arrhythmias in children with infectious diseases based on clinical and electrocardiographic analysis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: 3584 electrocardiograms (ECGs) of children with infectious diseases (average age 8.5 ± 5.3 years old; boys – 57.5%, girls – 42.5%) hospitalized in the Pediatric Research and Clinical Center for Infectious Diseases were analyzed. Patients with changes in the ECGs were given additional examination depending on the intended diagnosis (inherited arrhythmias): 24-Hour Holter ECG monitoring, stress test, echocardiography. The family history was also clarified, and the parents’ ECG was analyzed.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. ECG changes, which are typical for Brugada syndrome (type 1), were detected in two children (0.05%) at first. Long QT syndrome was also detected in two children (0,05%). Mutations in the SCN5A gene were identified in children with Brugada syndrome, and in the KCNQ1 gene with long QT syndrome. An episode of monomorphic ventricular tachycardia was recorded at night in a 5-year-old girl with atrioventricular block 1 degree, hypoadaptation of the QT interval with repeated Holter ECG monitoring during sleep. Cases of life-threatening ventricular arrhythmias have previously been described in the literature in patients with Brugada syndrome. An increase in body temperature leads to disruption of the sodium ion channels which underlie the development of this syndrome, thereby, on the one hand, increasing the risk of life-threatening arrhythmias and sudden cardiac death, on the other hand, to the clinical manifestation of the disease, allowing the diagnosis to be made in time. In the cases of long QT syndrome, in our study, the increase in the corrected QT interval (QTc) is most likely due to a change in heart rate rather than a direct effect of an increase in body temperature on the ion channels.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственные аритмии</kwd><kwd>синдром удлиненного интервала QT</kwd><kwd>синдром Бругада</kwd><kwd>болезнь Лева – Ленегра</kwd><kwd>инфекционные заболевания</kwd><kwd>лихорадка</kwd><kwd>дети</kwd><kwd>внезапная сердечная смерть</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inherited arrhythmias</kwd><kwd>long QT syndrome</kwd><kwd>Brugada syndrome</kwd><kwd>infectious diseases</kwd><kwd>fever</kwd><kwd>children</kwd><kwd>sudden cardiac death</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">Шилова М.А.
