Цель работы – поверхностное ЭКГ-картирование молодых крыс со стресс-индуцированной АГ в период деполяризации желудочков. Материал и методы. Исследование выполнено на трехмесячных самцах линии НИСАГ (n = 10) массой 250–300 г. Поверхностное ЭКГ-картирование проводили от 64 электродов, равномерно распределенных вокруг грудной клетки животного. Результаты и их обсуждение. Показано значимо большее систолическое давление у крыс линии НИСАГ по сравнению с крысами линии Вистар (203 ± 14 и 125 ± 5 мм рт. ст. соответственно), так же как относительная масса сердца, толщина левого желудочка и правого желудочка, межжелудочковой перегородки. В период деполяризации желудочков установлено смещение зоны отрицательных кардиопотенциалов в леволатеральную область грудной клетки в период, соответствующий времени достижения положительным экстремумом своего максимального значения, у крыс НИСАГ по сравнению с Вистар. Показано более раннее время формирования, значимо большее время достижения первой и второй инверсии кардиопотенциалов, более позднее время достижения положительным и отрицательным экстремумами своих максимальных значений, большая амплитуда абсолютного значения отрицательного экстремума и значимо большее общее время деполяризации желудочков у крыс НИСАГ по сравнению с крысами линии Вистар. Заключение. Проведенные исследования дают перспективу к использованию картирования ЭПС для диагностики начальных этапов формирования гипертрофии миокарда при АГ.</p></abstract><trans-abstract xml:lang="en"><p>Studies on experimental animals allow us to approach the understanding of the mechanisms of changes in the electrical activity of the heart during morphofunctional rearrangements that occur as a result of the development of arterial hypertension (AH). Aim of the study was to investigate body surface potential mapping in young ISIAH rats with genetically determined stress-induced AH during ventricular depolarization. Material and methods. The study was carried out on 3-month-old ISIAH males (n = 10) weighing 250–300 g. Body surface potential mapping was performed using 64 electrodes evenly distributed around the chest of the animal. Results. Significantly higher systolic blood pressure was shown in ISIAH rats compared to Wistar rats (203 ± 14 and 125 ± 5 mm Hg, respectively), as well as heart relative mass, thickness of the left ventricle, right ventricle, and interventricular septum were significantly higher compared to Wistar. During the period of ventricular depolarization, a shift of the zone of negative cardiopotentials to the left-lateral region of the chest is shown in the period corresponding to the time the positive extremum reaches its maximum value in ISIAH rats compared to Wistar. An earlier time of formation, a significantly longer time to achieve the first and second inversion of cardiopotentials, a later time for the positive and negative extrema to reach their maximum values, a greater amplitude of the absolute value of the negative extremum, and a significantly longer total ventricular duration in ISIAH rats compared to Wistar rats were shown. Conclusions. The study give perspective to the use of body surface potential mapping for diagnosing the initial stages of the formation of myocardial hypertrophy in AH.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностное ЭКГ-картирование</kwd><kwd>артериальная гипертензия</kwd><kwd>гипертрофия миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>body surface potential mapping</kwd><kwd>arterial hypertension</kwd><kwd>myocardial hypertrophy</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">Afzal M.R., Zanova S., Mohamed O., Vohamed-Osman A., Kalbfleisch S.J.
