Проведен предварительный литературный поиск. Наибольшее число цитирований приходилось на преобразование Корса и обратное преобразование Дауэра для получения вЭКГ по Франку. Кроме того, в анализ было решено включить преобразование Трунова-Айду, применяемое в нашей лаборатории для получения вЭКГ в системе отведений МакФи-Парунгао.В исследование были включены 1250 ЭКГ пациентов НМИЦ кардиологии с различными сердечно-сосудистыми заболеваниями. Для каждой ЭКГ с помощью названных преобразований были получены три вЭКГ с интактным и три вЭКГ с инвертированным направлением оси Z. Сопоставление проводилось по основным амплитудно-временным показателям P-QRS-T, а также по вЭКГ параметрам: пространственному углу QRS-T, площади петли QRS, интегральному вектору QRS, долевым интегралам P и QRS-T. Всего было проведено 9 попарных сравнений 134 показателей для каждой полученной вЭКГ.</p></sec><sec><title>Результаты</title><p>Результаты. При сопоставлении параметров вЭКГ, полученных вычислительными процедурами из ЭКГ по Корсу, Дауэру и Трунову-Айду наиболее сильная (r &gt; 0.9 либо r &lt; -0.9) и достоверная (p &lt; 0.001) линейная корреляционная связь подтверждена между пространственными показателями: длины петель P, QRS, T и площадь и показатели планарности петли QRS, пространственный угол QRS-T, желудочковый градиент, а также долевыми интегралами QRS. Менее сильная связь отмечена для проекционных показателей и амплитуды P-QRS-T. Наибольшее число корреляций было отмечено между показателями в системах Мак-Фи-Парунгао и Франка в пересчете по Корсу.</p></sec><sec><title>Выводы</title><p>Выводы. Существование сильной линейной связи между параметрами вЭКГ, определенными при пересчете по Корсу, Дауэру и Трунову-Айду, свидетельствует о возможности сопоставления результатов, полученных с помощью названных матриц в разных исследованиях</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to compare amplitude-temporal and vectorcardiographic (VCG) parameters calculated through most commonly used matrix transformations.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Preliminary literature search revealed Kors and inverse Dower transformation to be the most commonly used matrices for converting ECG‑12 into Frank VCG. Trunov-Aidu matrix appeared to be the only one for deriving VCG in the McFee-Parungao lead system.The study included 1250 ECGs of patients at the National Medical Research Center of Cardiology with various cardiovascular diseases: arterial hypertension, coronary heart disease, post-infarction cardiosclerosis, aortic stenosis. For each patient, using the above transformations, three VCGs with an intact and three VCGs with an inverted direction of the Z axis (according to Ozol) were obtained. The comparison was carried out based on the main amplitude-temporal indicators of P-QRS-T, as well as on VCG parameters: spatial QRS-T angle, QRS loop area, QRS integral vector, fractional integrals P and QRS. A total of 9 pairwise comparisons of 134 indicators were carried out for each synthesized VCG</p></sec><sec><title>Results</title><p>Results. The strongest (r &gt; 0.9 or r &lt; -0.9) significant (p &lt; 0.001) linear correlation was found between the spatial metrics: P, QRS, T wave loop lengths, QRS loop area, QRS-T angle, ventricular gradient, and QRS shared integrals. Significant relationship between projection parameters and P-QRS-T amplitude and duration was observed in some cases. The largest number of correlations was noted between parameters calculated in McFee-Parungao and Frank lead system derived by Kors.</p></sec><sec><title>Conclusions</title><p>Conclusions. Strong linear relationship was found between the VCG parameters determined through Kors, Dower and Trunov-Aidu matrix transformations, which indicates the equivalence of the results obtained through these matrices.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>электрокардиография</kwd><kwd>ЭКГ</kwd><kwd>электрокардиография ортогональная</kwd><kwd>векторкардиография</kwd><kwd>матричное преобразование</kwd><kwd>система отведений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrocardiography</kwd><kwd>ECG</kwd><kwd>orthogonal</kwd><kwd>vectorcardiography</kwd><kwd>matrix transformation</kwd><kwd>lead system</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">Pérez-Riera A.R., Barbosa-Barros R., Daminello-Raimundo R et al.
