Глубокий вдох вызывает целый спектр физиологических эффектов, находящих отражение на электрокардиограмме.</p><p>   Цель исследования – оценить положение электрической оси сердца во время глубокого вдоха по сравнению со спокойным дыханием у больных прекапиллярной легочной гипертензией и сопоставить эти данные с эхокардиографическими характеристиками структурно-функционального состояния сердца.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. В исследование были включены 40 пациентов идиопатической легочной гипертензией и 40 пациентов хронической тромбоэмболической легочной гипертензией. При эхокардиографии оценивались размеры камер сердца, систолическая и диастолическая функция правого и левого желудочков, давление в легочной артерии, легочное сосудистое сопротивление, показатели сердечно-сосудистого сопряжения.</p></sec><sec><title>   Результаты</title><p>   Результаты. Значения электрической оси сердца при свободном дыхании составили 106° [84°; 123°], на вдохе – 89° [87°; 120°] (р = 0,68). У 50 (62,5 %) пациентов во время глубокого вдоха происходило смещение электрической оси сердца влево от исходной, а у 30 (37,5 %) пациентов – вправо от исходной. У больных со смещением электрической оси сердца влево от исходной по сравнению с остальными конечный диастолический размер левого желудочка, конечный диастолический и конечный систолический объемы левого желудочка, ударный объем, сердечный выброс были статистически значимо меньше, а индекс эксцентричности, легочное сосудистое сопротивление и эффективная жесткость аорты – значимо больше.</p></sec><sec><title>   Заключение</title><p>   Заключение. У больных прекапиллярной легочной гипертензией выявлено два варианта изменений положения электрической оси сердца во время глубокого вдоха: смещение вправо от исходной и влево от исходной. Больные со смещением электрической оси сердца влево от исходной характеризовались значимо большим увеличением легочного сосудистого сопротивления, снижением объемов левого желудочка, ударного объема и сердечного выброса.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. A deep breath causes a whole range of physiological effects that are reflected in the electrocardiogram.</p><p>   The purpose of the study is to assess the position of the electrical axis of the heart during deep inspiration compared to quiet breathing in patients with precapillary pulmonary hypertension and compare these data with echocardiographic characteristics of the structural and functional state of the heart.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. The study included 40 patients with idiopathic pulmonary hypertension and 40 patients with chronic thromboembolic pulmonary hypertension. Echocardiography assessed the size of the heart chambers, systolic and diastolic function of the right and left ventricles, pulmonary artery pressure, pulmonary vascular resistance and indicators of cardiovascular coupling.</p></sec><sec><title>   Results</title><p>   Results. The values of the electrical axis of the heart during free breathing were 106° [84°; 123°], on inspiration – 89° [87°; 120°] (p = 0.68). In 50 (62.5 %) patients, during a deep inspiration, the electrical axis of the heart shifted to the left from the original one, and in 30 (37.5 %) patients – to the right. In patients with a displacement of the electrical axis of the heart to the left from the original, compared with the others, the end-diastolic size of the left ventricle, end-diastolic and end-systolic volumes of the left ventricle, stroke volume, cardiac output were statistically significantly lower, and the eccentricity index, pulmonary vascular resistance and effective aortic stiffness – significantly larger.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. In patients with precapillary pulmonary hypertension, two variants of changes of the heart electrical axis during deep inspiration were identified: a shift to the right from the original and to the left from the original. Patients with a displacement of the electrical axis to the left from the original were characterized by a significantly greater increase in pulmonary vascular resistance, a decrease in left ventricular volumes, stroke volume and cardiac output.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>электрокардиограмма</kwd><kwd>вдох</kwd><kwd>легочная гипертензия</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrocardiogram</kwd><kwd>inspiration</kwd><kwd>pulmonary hypertension</kwd><kwd>echocardiography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют об отсутствии финансирования</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дроздов ДВ, Макаров ЛМ, Баркан ВС, Газашвили ТМ, Ефимова ВП, Жук МЮ, Иртюга ОБ, Калинин ЛА, Ковалёв ИА, Комолятова ВН, Пармон ЕВ, Рогоза АН, Стручков ПВ, Татаринова АА, Терегулов ЮЭ, Трешкур ТВ, Шутов ДВ.
