Обобщить имеющиеся в настоящее время сведения о механизмах развития, клинической картине, диагностике и терапевтических подходах при синдроме удлиненного интервала QT.</p></sec><sec><title>Основные положения</title><p>Основные положения. Врожденный синдром удлиненного интервала QT — наследственное заболевание, характеризующееся увеличением длительности фазы реполяризации желудочков сердца, а следовательно, удлинением интервала QT на электрокардиограмме. Он сопровождается фатальными нарушениями ритма сердца, эпизодами синкопальных состояний и случаями внезапной сердечной смерти. Описаны шестнадцать генов, связанных с наследственным синдромом удлиненного интервала QT, а генетическое тестирование стало неотъемлемой частью диагностики этой патологии и стратификации риска.</p></sec><sec><title>Заключение</title><p>Заключение. Новые знания о структуре данных белков способствуют более глубокому пониманию проблемы каналопатий, в частности синдрома удлиненного интервала QT, который является наиболее хорошо изученным из этой группы заболеваний. Кроме того, продолжающийся прогресс в понимании генетических основ и механизмов развития синдрома удлиненного интервала QT приводит к появлению более эффективных, таргетных, основанных на индивидуальном подходе стратегий лечения синдрома.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To summarize the currently available information on the pathophysiological mechanisms, clinical management, diagnosis and therapeutic approaches in congenital long QT syndrome.</p></sec><sec><title>Key points</title><p>Key points. Congenital long QT syndrome is a hereditary disease characterized by an increased ventricles repolarization time, and, consequently, a lengthening of the QT interval on the electrocardiogram. It is accompanied by fatal cardiac arrhythmias, episodes of syncope and cases of sudden cardiac death. Sixteen genes associated with hereditary long QT syndrome have been described, and genetic testing has become an integral part of the diagnosis of this pathology and risk stratification.</p></sec><sec><title>Conclusion</title><p>Conclusion. New knowledge about the structure of these proteins contributes to a deeper understanding of the problem of channelopathy, in particular, long QT syndrome, which is the most well-studied of this group of diseases. In addition, continued progress in understanding the genetic basis and mechanisms of development of long QT syndrome leads to the emergence of more effective, targeted, individualized treatment strategies for the syndrome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром удлиненного интервала QT</kwd><kwd>электрокардиография</kwd><kwd>удлиненный интервал QT</kwd><kwd>torsade de pointes</kwd><kwd>ионные каналы</kwd><kwd>желудочковая тахикардия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>congenital long QT syndrome</kwd><kwd>еlectrocardiography</kwd><kwd>long QT interval</kwd><kwd>torsades de pointes</kwd><kwd>ion channels</kwd><kwd>ventricular tachycardiа</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">Jervell A., Lange-Nielsen F.
