Описаны родные сестры, чей отец страдал от тяжелой формы гипертрофической кардиомиопатии в сочетании с синдромом Вольфа–Паркинсона–Уайта и умер в молодом возрасте от прогрессирующей сердечной недостаточности. Характерна ранняя манифестация заболевания, при этом имелось сочетание синдрома преэкзитации желудочков и гипертрофии миокарда с быстрым прогрессированием до достижения экстремальных значений. Гипертрофия была концентрической симметричной, носила бивентрикулярный характер.Основным клиническим симптомом в  первом наблюдении были частые пароксизмы суправентрикулярной тахикардии. Отмечено выявление новых предсердно-желудочковых сообщений в ходе динамического наблюдения, недостаточная эффективность радиочастотной аблации, рецидивы суправентрикуляной тахикардии, хороший эффект от назначения пропафенона. Третий клинический случай спорадический (представлено длительное наблюдение в течение 15 лет) и ярко отражает проградиентность нарастания гипертрофии миокарда и нарушений ритма сердца. Заболевание дебютировало с раннего возраста в виде гипертрофии в сочетании с выраженной брадикардией, что затрудняло медикаментозную терапию. В связи с высоким риском внезапной сердечной смерти на фоне экстремальной гипертрофии миокарда имплантирован кардиовертер-дефибриллятор. Описаны признаки митохондриальной недостаточности по данным биопсии скелетной мышцы. </p></abstract><trans-abstract xml:lang="en"><p>Clinical observations of three cases of hypertrophic cardiomyopathy caused by mutations in the PRKAG2 gene with a debut in early childhood are presented. The  sisters whose father suffered from a severe form of  hypertrophic cardiomyopathy in  combination with Wolf—Parkinson—White syndrome and died at a young age from progressive heart failure are described. Early manifestation of  the disease is characteristic, while there was a combination of  ventricular preexitation syndrome and myocardial hypertrophy with rapid progression to extreme values. Hypertrophy was concentric symmetrical and biventricular. The main clinical symptom in  the first observation was frequent paroxysms of supraventricular tachycardia. New atrioventricular fenestrations were detected during dynamic observation, insufficient effectiveness of radiofrequency ablation, recurrence of supraventricular tachycardia, and a good response to propafenone were noted. The third clinical case is sporadic, a long-term follow-up for 15 years is presented and clearly reflects the progression of  the increase in myocardial hypertrophy and cardiac arrhythmias. The disease debuted from an early age in the form of hypertrophy in combination with severe bradycardia, which made drug therapy difficult. Due to the high risk of sudden cardiac death against the background of extreme myocardial hypertrophy, a cardioverter defibrillator was implanted. Signs of mitochondrial insufficiency according to skeletal muscle biopsy are described. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>PRKAG2</kwd><kwd>гипертрофическая кардиомиопатия</kwd><kwd>синдром Вольфа–Паркинсона–Уайта</kwd><kwd>радиочастотная аблация</kwd><kwd>антиаритмическая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>PRKAG2</kwd><kwd>hypertrophic cardiomyopathy</kwd><kwd>Wolf—Parkinson—White syndrome</kwd><kwd>radiofrequency ablation</kwd><kwd>antiarrhythmic 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">Blair E., Redwood C., Ashrafian H., Oliveira M., Broxholme J., Kerr В. et al.
