Оценить электрокардиографические (ЭКГ) и векторкардиографические (ВКГ) показатели при различных типах структурно-геометрического ремоделирования левого желудочка (ЛЖ) у пациентов с артериальной гипертензией (АГ).</p><p>Материал и методы исследования. Анализ выполнен у 336 человек, из них 264 пациента с АГ, средний возраст 61,02±7,61 года, и 72 практически здоровых пациента (57,18±6,47). Оценены ЭКГ показатели, ЧСС и продолжительность Р, QRS, RR, PQ, QT, QT корригированного по формулам Bazett, Friderici и Sagie (QT CB, QT CF , QT CS ). По ЭхоКГ рассчитаны масса миокарда (ММЛЖ) и индекс ММЛЖ (ИММЛЖ), относительная толщина стенок (ОТС). В собственной плоскости ВКГ определены: площадь петли QRS (SQRS), величина максимального вектора (maxQRS).</p></sec><sec><title>Результаты</title><p>Результаты.Корреляционный анализ показал наличие положительной связи ММЛЖ и ИММЛЖ с SQRS (r=0,49 и r=0,38), mаxQRS (r=0,28 и r=0,33) и с продолжительностью QRS (r=0,50 и r=0,43). Группы пациентов с концентрической (КГ) и эксцентрической (ЭГ) гипертрофией в сравнении с контролем и пациентами с АГ без ГЛЖ дали достоверно большие значения абсолютного QT, QT CF, QT CS. Была выявлена положительная корреляционная связь QT и QTС с ММЛЖ, ИММЛЖ и отсутствие взаимосвязи с ОТС.</p></sec><sec><title>Выводы</title><p>Выводы. При ГЛЖ увеличивалась продолжительность QRS и SQRS в собственной плоскости. Наибольшие значения SQRS наблюдались у пациентов с КГ левого желудочка в сравнении с ЭГ. По продолжительности QRS пациенты с КГ и ЭГ не различались. У пациентов с АГ и ГЛЖ продолжительность абсолютных и корригированных значений интервала QT была достоверно больше, чем у пациентов без ГЛЖ.</p><p>Интервал QT удлинялся с увеличением ММЛЖ и ИММЛЖ. Продолжительность QT не зависела от типа гипертрофии ЛЖ — концентрическая или эксцентрическая.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Study electrocardiographic (ECG) and vectorcardiographic (VCG) indicators for various types of structural-  geometric remodeling of the left ventricle (LV) in patients with arterial hypertension (AH).</p><p>Material and research methods. The analysis was performed in 336 people, including 264 patients with AH, mean age 61.02 ± 7.61 years and 72 practically healthy individuals (57.18 ± 6.47). The ECG indicators of heart rate and duration of P, QRS, RR, PQ, QT, QT corrected according to the Bazett, Friderici and Sagie formulas (QTCB, QTCF, QTCS) were assessed. Echocardiography was used to calculate myocardial mass (LVMM) and LVMM index (LVMI), relative wall thickness (RWT). In the own plane of the VCG: the area of the QRS loop (SQRS), the magnitude of the geometric vector (maxQRS) were determined.</p></sec><sec><title>Results</title><p>Results. Correlation analysis showed the presence of a positive relationship between LVM and LVMI with SQRS (r = 0.49 and r = 0.38), maxQRS (r = 0.28 and r=0.33) and with QRS duration (r = 0.50 and r = 0.43). The groups of patients with concentric (CG) and eccentric (EH) hypertrophy in comparison with controls and patients with AH without LVH gave significantly higher values of absolute QT, QTCF, QTCS. There was a positive correlation between QT and QTС with LVMM, LVMI and no relationship with RWT.</p></sec><sec><title>Conclusions</title><p>Conclusions. In LVH, the duration of QRS and SQRS in its own plane increased. The highest SQRS values were observed in patients with CG of the left ventricle in comparison with EG. Patients with CG and EG did not differ in QRS duration. In patients with AH and LVH, the duration of absolute and corrected values of the QT interval was significantly longer than in patients without LVH. The QT interval lengthened with an increase in LVMM and LVMI. QT duration did not depend on the type of LV hypertrophy — concentric or eccentric.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертензия</kwd><kwd>гипертрофия левого желудочка</kwd><kwd>электрофизиологическое ремоделирование</kwd><kwd>структурно-геометрическое ремоделирование</kwd><kwd>интервал QT</kwd><kwd>интервал QT корригированный</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arterial hypertension</kwd><kwd>left ventricular hypertrophy</kwd><kwd>electrophysiological remodeling</kwd><kwd>structural-  geometric remodeling</kwd><kwd>QT interval</kwd><kwd>corrected QT interval</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">Бадин Ю.
