Регистрация ЭКГ осуществлялась с помощью компьютеризированного электрокардиографа в 12 общепринятых отведениях и системе ортогональных отведений по Франку в течение 5 минут. Для математического усреднения ЭКГ использовалась разработанная нами программа «HR ECG». При определении воспроизводимости методов оценивались сумма продолжительностей зубца Р, интервала РQ, комплекса QRS и амплитуд зубцов P, Q, R, S и Т в оператор-независимых отведениях — I стандартном при регистрации в 12 отведениях и Y при регистрации в системе ортогональных отведений по Франку традиционной и усредненной ЭКГ, а также наиболее широко используемые индексы гипертрофии левого желудочка (ГЛЖ): Sokolow-Lyon, Cornell voltage, Cornell product.</p></sec><sec><title>Результаты</title><p>Результаты. Коэффициент вариабельности для временных показателей при повторных исследованиях для традиционной и усредненной ЭКГ составил 13,1 % против 4,8 % (p &lt; 0,01) для I стандартного отведения и 16 % против 4,8 % (p &lt; 0,01) для отведения Y соответственно. Коэффициент вариабельности для амплитудных показателей при повторных исследованиях для традиционной и усредненной ЭКГ составил 12,2 % против 7,2 % (p &lt; 0,01) для I стандартного отведения и 10,3 % против 6,7 % (p &lt; 0,05) для отведения Y соответственно. Для индексов ГЛЖ Sokolov-Lyon, Cornell voltage, Cornell product по данным неусредненной и усредненной ЭКГ вариабельность составила 12,3; 16,9 и 12,8 % против 8,0; 14,2 и 10,1 % соответственно (p &lt; 0,05 для всех показателей).</p></sec><sec><title>Выводы</title><p>Выводы. Воспроизводимость усредненной ЭКГ значительно превышает традиционный метод, как в отношении амплитудных, так и временных характеристик, а также индексов ГЛЖ сердца. Использование метода в клинической практике повысит надежность индивидуализированной оценки изменений миокарда при одномоментном исследовании и в динамике, а в исследованиях с ЭКГ контролем позволит сократить время или объем групп для достижения статистически значимого результата.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. The aim of our study was to compare the reproducibility of signal-averaged and conventional electrocardiogram (ECG).</p></sec><sec><title>Design and methods</title><p>Design and methods. The study group included 20 young healthy volunteers (10 men and 10 women, aged 18–25 years) examined twice with one-week interval. Twelve-lead and Frank’s orthogonal system ECG recordings were acquired during 5 minutes using computerized ECG device at each examination; conventional and averaged ECG analyses were performed. Mathematical processing to get averaged ECG in each lead was performed using original program «HR ECG». The sum of P wave, PQ interval, and QRS durations and the sum of P, Q, R, S, T waves amplitudes (amplitudes) in lead I of 12‑lead ECG and in lead Y in Frank’s lead system and left ventricular hypertrophy (LVH) indices (Sokolow-Lyon, Cornell voltage, Cornell product) were used for the evaluation of reproducibility.</p></sec><sec><title>Results</title><p>Results. Variation coefficients of durations between two evaluations of conventional and signal-averaged ECG were 13,1 % versus 4,8 % (p &lt; 0,01) for lead I and 16 % versus 4,8 % (p &lt; 0,01) for lead Y, respectively. Variation coefficients of amplitudes between two examinations of conventional and signal-averaged ECG were 12,2 % versus 7,2 % (p &lt; 0,01) for lead I and 10,3 % versus 6,7 % for lead Y (p &lt; 0,05), respectively. Variation coefficients of Sokolow-Lyon index, Cornell voltage and Cornell product were 12,3; 16,9 и 12,8 % versus 8,0; 14,2 и 10,1 %, respectively (p &lt; 0,05 for all variables).</p></sec><sec><title>Conclusions</title><p>Conclusions. The reproducibility of the signalaveraged ECG is significantly higher than the conventional one for interval duration, wave amplitude, as well as for LVH indices. The use of this method in clinical practice will increase the reliability of individual evaluation of myocardial changes at single examination and during follow-up. In studies with ECG control it may contribute to the decrease in study duration or group size required to reach statistically significant differences.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>усредненная электрокардиография</kwd><kwd>воспроизводимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>signal-averaged electrocardiography</kwd><kwd>reproducibility</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">Оганов Р.
