К этим факторам относятся наследственные и приобретенные ка­ налопатии. Многие опасные изменения в работе ионных каналов сердца могут быть идентифицированы с помощью электрокардио­ граммы пациента. К легко выявляемым изменениям относится синдром удлинения интервала QT (LQTS) на электрокардиограмме. Несмотря на весьма широкую распространенность наследствен­ ного LQTS, к которому нужно добавить и вынужденный LQTS, появ­ ляющийся под действием широкого класса фармацевтических препаратов, а также простоту выявления синдрома на ЭКГ, до сих пор не известен механизм образования реентри при этом синдроме. Следует отметить высокую вариативность синдрома (встреча­ емость 1:2500), а также факт связи увеличения частоты сердечных сокращений индивида и значительного повышения риска останов­ ки работы сердца. После достаточно экстенсивного проведения электрофизиологических исследований на отдельных сердечных клетках, получаемых от пациентов с синдромом LQT, стало очевид­ но, что поиск механизма перехода нормального ритма сердца в хаотический и фибрилляцию не может ограничиваться регистра­ цией ионных токов в единичных клетках. Для решения такой зада­ чи прежде всего необходима модель поведения сердечной ткани как многоклеточного ансамбля, отражающая связь различных факторов (сбой работы мембранных ионных каналов, действие лекарств, изменения процессов, межклеточные взаимодействия) с риском возникновения реентри. С целью создания эксперимен­ тальной модели LQTS в нашей работе индуцированные плюрипотентные стволовые клетки (ИПСК) пациент-специфичной линии от здорового пациента были дифференцированы в монослой, идентифицированы при помощи иммуноцитохимии и patch-clamp исследованы параметры распространения возбуждения в зави­ симости от стадии дифференцировки. Показано, что стабильное значение скорости проведения и ответ на периодическую стиму­ ляцию в диапазоне физиологических величин достигаются после 30-го дня дифференцировки.</p></abstract><trans-abstract xml:lang="en"><p>There are risk factors that lead the normal conduction of excitation in the heart into a chaotic one. These factors include hereditary and acquired channelopathies. Many dangerous changes in the work of the heart can be identified using the patient’s electrocardiogram. Such relatively easily detectable changes include the long QT interval syndrome (LQTS). Despite a relatively high prevalence of hereditary LQTS, to which it is necessary to add both hereditary and induced LQTS as well as the ease of detection on the ECG, the mechanism of reentry formation in this syndrome is still un­known. What should be noted is a high variability of the hereditary syndrome and the fact of the connection between the increase in the heart rate and the risk of cardiac arrest. After an electrophysiological study on individual cardiac cells from patients with the LQT syndrome, it became apparent that the search for a mechanism for the transition of the normal heart rhythm to chaotic and fibrillation cannot be limited to recording ion currents in single cells. To solve this problem, we need a model of the behavior of cardiac tissue which reflects the relationship of various factors and the risk of reentry. In order to create an experimental model of LQTS in our work, the iPSC of a pati­ent-specific line from a healthy patient was differentiated into a monolayer of cardiac cells and the parameters of the excitation propagation were studied depending on the stage of differentiation. It was shown that a stable value of the propagation velocity and the response to periodic stimulation in the range of physiological values, are reached after the 30th day of dif­ferentiation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аритмогенность</kwd><kwd>пациент-специфичность</kwd><kwd>индуцированные плюрипотентные стволовые клетки (ИПСК)</kwd><kwd>синдром удлинения интервала QT (LQTS)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arrhythmogenicity test</kwd><kwd>patient specificity</kwd><kwd>induced pluripotent stem cells (iPSC)</kwd><kwd>the long QT interval syndrome (LQTS)</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">Burridge P.W., Matsa E., Shukla P., Lin Z.C., Churko J.M., Ebert A.D., Lan F., Diecke S., Huber B., Mordwinkin N.M., Plews J.R., Abilez O.J., Cui B., Gold J.D., Wu J.C.
