To study effects of sympathomimetic agents on electrocardiogram (ECG) indexes in patients with bronchial asthma (BA) in exacerbation stage complicated by respiratory insufficiency and sympathomimetic agents overdose.</p></sec><sec><title>Material and methods</title><p>Material and methods. 40 patients with persistent BA of various severities with respiratory insufficiency and sympathomimetic agents overdose were investigated. ECG was performed and P wave, QRS, duration and dispersion of corrected QT interval (QTc) were analyzed.</p></sec><sec><title>Results</title><p>Results. Mean QTc dispersion correlated with asthma severity and was 76,8±5,9 ms1/2, 87,9±5,1 ms1/2, 87,8±3,1 ms1/2 in patients with mild, moderate and severe BA, respectively. Significant correlation between QTc dispersion and BA duration was found. QTc dispersion level was directly connected with duration of use of β-agonists and their overdose. Average QTc dispersion in patients who used more than 20 daily doses of inhaled β-agonists was 89,0±5,8 ms1/2.</p></sec><sec><title>Conclusion</title><p>Conclusion. Increase in QTc dispersion directly depends on BA duration and severity. β-agonist overdose results in growth of QTc dispersion, which has arrhythmogenic potential.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить влияние симпатомиметиков на электрокардиографические показатели у больных бронхиальной астмой (БА) в период обострения заболевания, осложненного дыхательной недостаточностью и передозировкой симпатомиметиков.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование было включено 40 больных персистирующей формой БА легкого, среднетяжелого и тяжелого течения, осложненного дыхательной недостаточностью и передозировкой симпатомиметиков. Всем больным проводилось электро-кардиографическое исследование с последующим анализом зубца Р, интервалов QRS, QT, расчетом продолжительности и дисперсии корригированного интервала QT (dQTc).</p></sec><sec><title>Результаты</title><p>Результаты. Величина dQTc коррелировала со степенью тяжести БА и составила 76,8±5,9 мс1/2, 87,9±5,1 мс1/2, 87,8±3,1 мс1/2 при БА легкого, среднетяжелого и тяжелого течения, соответственно. Была выявлена положительная корреляция между dQTc и длительностью БА. Величина dQTc зависела от длительности приема β-агонистов и наличия их передозировки. В группе больных с частотой приема симпатомиметиков более 20 доз в сутки средняя продолжительность dQTc составила 89,0±5,8 мс1/2.</p></sec><sec><title>Заключение</title><p>Заключение. dQTc возрастает с увеличением продолжительности БА и зависит от степени тяжести БА. Передозировка β-агонистов приводит к увеличению dQTc, что прогностически неблагоприятно в отношении нарушений ритма.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бронхиальная астма</kwd><kwd>передозировка симпатомиметиков</kwd><kwd>нарушения ритма</kwd><kwd>дисперсия интервала QT</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bronchial asthma</kwd><kwd>sympathomimetic agent overdose</kwd><kwd>rhythm disorders</kwd><kwd>dispersion of 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">Белоусов Ю.Б., Омельяновский В.В.
