Изучить электрокардиологические закономерности формирования тилт-индуцированных кардиоингибиторных (КИ) реакций у детей и подростков. Материал и методы. В исследование было включено 16 детей (10 мальчиков) в возрасте 8–18 лет с рецидивирующими обмороками в анамнезе и установленным при проведении тилт-теста (ТТ) КИ механизмом развития синкопе. Безмедикаментозный ТТ проводился по Вестминстерскому протоколу. ЭКГ регистрировалась непрерывно, все записи обрабатывались мануально. Для сравнительного анализа были взяты трехминутные фрагменты ЭКГ перед наклоном стола, после вертикализации, перед и в момент развития синкопе и в период восстановления. Результаты. Показана высокая представленность на ЭКГ покоя у детей с КИ синкопе признаков усиления парасимпатических влияний в регуляции сердечного ритма. Ранний ортостаз характеризовался увеличением частоты сердечных сокращений (ЧСС) на 35,8±11,5%. В процессе ортостатической нагрузки и до момента развития синкопе ЧСС достоверно (p=0,001) возросла относительно значений начала ортостаза. Развитие обморока начиналось с замедления частоты ритма, предваряющего кардиоингибицию, которая возникала остро или после короткого периода нарушения синоатриального и/или АВ-проведения. Восстановительный период характеризовался достоверно более низкой ЧСС по сравнению с исходными значениями (p=0,0006) и высокой частотой регистрации вагус-ассоцированных аритмий. Заключение. ЭКГ-паттерн развития КИ синкопе у детей характеризуется нарастающей симпатической активацией с последующим резким сдвигом регуляторного контроля работы сердца в сторону парасимпатического звена. Выраженность вагальной активации определяет ЭКГ-картину как в момент развития обморока, так и в периоде восстановления.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Aim. To study electrocardiographic patterns of tilt-induced cardioinhibitory (CI) reactions in children and adolescents. Material and methods. The study included 16 children and adolescents (10 boys), aged 8-18 years, with recurrent syncope in anamnesis and CI syncope mechanisms confirmed by the tilt table test (TTT) results. Medication-free TTT was performed according to the Westminster protocol, with continuous electrocardiography; all records were processed manually. The following electrocardiogram (ECG) records (3 minutes each) were analysed: before the table tilt; in the head-up position; before the syncope; during the syncope; and during the recovery phase. Results. In children and adolescents with CI syncope, the baseline ECG demonstrated increased parasympathetic influence on heart rate (HR) regulation. Early orthostasis was characterised by increased HR (+35,8±11,5%). During the increase in orthostatic stress and before the syncope development, HR additionally and significantly increased (p=0,001 vs. early orthostasis). Syncope development was associated with HR reduction and subsequent cardioinhibition, either acute, or after a short period of disturbed sinoatrial and/or atrioventricular conductivity. The recovery phase was characterised by a significant HR reduction, compared to the baseline (p=0,0006), and frequent vagal-associated arrhythmias. Conclusion. ECG patterns of CI syncope in children and adolescents demonstrate increased sympathetic influences on HR regulation, followed by acute parasympathetic activation. The degree of vagal activation defines ECG patterns during syncope development and recovery phase.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синкопе</kwd><kwd>тилт-тест</kwd><kwd>электрокардиограмма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Syncope</kwd><kwd>tilt-test</kwd><kwd>electrocardiogram</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">Guidelines for the diagnosis and management of syncope.
