Пароксизмальные суправентрикулярные аритмии у таких больных протекают с тяжелыми клиническими проявлениями, нередко сопровождаются гемодинамической нестабильностью и синкопальными состояниями. Представлен клинический случай пациентки К., 59 лет с ДКМП, сниженной фракцией выброса левого желудочка (35-37%), блокадой левой ножки пучка Гиса и пароксизмальной ортодромной реципрокной тахикардией. При постановке диагностического электрода в верхушку правого желудочка в ходе процедуры радиочастотной аблации добавочного пути проведения у пациентки было отмечено возникновение полной поперечной блокады. Сохранение полной поперечной блокады в течение операции, ее рецидивы при попытках удаления электрода из верхушки правого желудочка потребовали обеспечения временной, а  затем постоянной электрокардиостимуляции. Учитывая ДКМП, со снижением фракции выброса левого желудочка, наличие блокады левой ножки пучка Гиса и высокий ожидаемый процент стимуляции правого желудочка, принято решение об имплантации сердечного ресинхронизирующего устройства с функцией дефибриллятора. В обзоре литературы рассмотрены факторы риска развития полной поперечной блокады в ходе катетеризации сердца, возможности профилактики этого опасного осложнения, обсуждены прогностическая значимость катетериндуцированных нарушений проводимости, показания к временной и постоянной электрокардиостимуляции.</p></abstract><trans-abstract xml:lang="en"><p>Patients with dilated cardiomyopathy (DCM) often have intraventricular conduction disorders, which contribute to aggravation of heart failure, are progressive in most cases and can specify the prognosis of the disease. Paroxysmal supraventricular arrhythmias in such patients proceed with severe clinical manifestations, often accompanied by hemodynamic instability and syncope. A case report of patient (59 years old) with DCM, reduced left ventricular ejection fraction (35-37%), left bundle branch block, and paroxysmal orthodromic reciprocating tachycardia is presented. When an electrode was inserted on the right ventricular (RV) apex during the radiofrequency ablation, a third-degree atrioventricular (AV) block was recorded. This was maintained during the operation and was recurrent when trying to remove the electrode from the RV apex, and therefore there was a need for temporary and then permanent cardiac pacing therapy. Given DCM, reduced left ventricular ejection fraction, left bundle branch block, and the expected high percentage of RV pacing, a decision was made to implant a cardiac resynchronization therapy defibrillator. The literature review considers risk factors for formation of third-degree AV block during cardiac catheterization, methods of its prevention, as well as discusses the prognostic significance of catheter-induced conduction disorders, and indications for temporary and permanent cardiac pacing therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наджедудочковая тахикардия</kwd><kwd>дилатационная кардиомиопатия</kwd><kwd>радиочастотная аблация</kwd><kwd>полная атриовентрикулярная блокада</kwd><kwd>сердечная ресинхронизирующая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>supraventricular tachycardia</kwd><kwd>dilated cardiomyopathy</kwd><kwd>radiofrequency ablation</kwd><kwd>third-degree atrioventricular block</kwd><kwd>cardiac resynchronization therapy</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">Zannad F, Huvelle E, Dickstein K, et al.
