To accumulate the data on the range of standard values of the left atrium (LA) mechanical function indices using the technique of vector analysis of endocardium movement velocity in healthy adults. Materials and methods. 144 healthy adult volunteers aged 18-64 (40,4±13) years were examined. All of them underwent echocardiography using the technique of vector analysis of endocardium movement velocity. The global (integral) endocardium movement velocity (vel), strain rate (SR) and longitudinal strain (LS) indices of the left atrium were obtained. These indices were studied to assess the local (segmental) values from the chosen points. Results. While studying mechanical function in healthy subjects, indices characterizing a global mechanical function of the left atrium and those demonstrating contribution of each LA segment during different phases of LA cycle were received. The left atrium roof indices were found to have lower strain rate and strain indices and higher figures of regional side and low wall indices. Conclusion. The obtained data on the strain rate and longitudinal strain can be used as standard ones to assess LA mechanical function.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Накопление фактических данных о диапазоне нормальных значений показателей механической функции левого предсердия (ЛП), полученных методом векторного анализа скорости движения эндокарда у здоровых взрослых. Материалы и методы. Обследованы 144 здоровых взрослых добровольцев от 18 до 64 лет (в среднем - 40,4±13,0 г.). Всем проводили эхокардиографию с использованием технологии векторного анализа скорости движения эндокарда. Получали показатели глобальной (интегральной) скорости движения эндокарда ( vel ), скорости деформации (stain rate, SR ) и продольной деформации (strain, S ) ЛП. Эти же показатели изучались для оценки локальных (сегментарных) значений из выбранных точек. Результаты. При изучении механической функции здоровых лиц получили данные, характеризующие глобальную механическую функцию ЛП, и показатели, демонстрирующие вклад каждого сегмента в разные фазы цикла работы ЛП. Было выявлено, что показатели крыши ЛП имеют более низкие значения скорости деформации, в свою очередь, мы отмечаем более высокие цифровые значения региональных показателей боковой и нижней стенок, а также межпредсердной перегородки. Выводы. Полученные данные скорости деформации и продольной деформации могут быть использованы как нормативные для оценки механической функции ЛП.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Left atrium</kwd><kwd>mechanical function</kwd><kwd>visualization velocity vector</kwd><kwd>strain</kwd><kwd>strain rate</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Левое предсердие</kwd><kwd>механическая функция</kwd><kwd>вектор скорости визуализации</kwd><kwd>деформация</kwd><kwd>скорость деформации</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Алехин М.
