To study correlations between glycemia and duration of ventricular repolarization in children and adolescents with type 1 diabetes mellitus (DM).
Material and methods. Parallel monitoring of ECG and glycemia was conducted in 43 type 1 MD patients (age 7-17 years, 12.8 ± 2.7) and 37 healthy children and adolescents.
Results. Glycemia under 3 mmol/l and over 19 mmol/l is associated with significantly longer QTc interval compare to other blood glucose levels (437 ms and 447 ms versus 430 ms, p &lt; 0.01). Also, in these glycemia values QTc interval duration over 440 ms (46 and 62% versus 33%; p&lt;0.01) becomes more frequent. In healthy children and adolescents mean duration and frequency of a longer QTc interval were significantly less than in diabetic patients irrespective of glycemia degree in patients with type 1 DM (p &lt; 0.01). A moderate correlation was found between a daily insulin dose and QTc duration (correlation coefficient 0.35, p = 0.02).
Conclusion. Glycemia under 3 mmol/l and over 19 mmol/l can prolong QT interval and, therefore, raise the risk of cardiovascular death in patients with type 1 DM.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Оценить влияние динамики гликемии на длительность интервала QT у больных сахарным диабетом (СД) 1-го типа.
Материалы и методы. У 43 больных СД 1-го типа в возрасте от 7-17 лет (12,8 ± 2,7 года) было проведено параллельное мониторирование ЭКГ и гликемии. Контрольную группу составили 37 здоровых детей и подростков.
Результаты. Установлено, что при гликемии ниже 3 ммоль/л и свыше 19 ммоль/л происходит достоверное удлинение QTc по сравнению с другими значениями глюкозы в крови (437 и 447 мс против 430 мс; p &lt; 0,01). Также при этих значениях гликемии достоверно увеличивалась частота удлинения интервала QTc свыше 440 мс (46 и 62 % против 33%; p &lt; 0,01). У здоровых детей и подростков средняя длительность и частота удлинения интервала QTc были достоверно меньше, чем у больных СД 1-го типа, независимо от уровня гликемии у больных СД (p &lt; 0,01). Также была выявлена умеренная корреляция между вводимой за сутки дозой инсулина и длительностью QTc (коэффициент корреляции 0,35; p = 0,02).
Заключение. К удлинению интервала QT у больных СД 1-го типа могут предрасполагать как гипо- так и гипергликемия.</p></trans-abstract><kwd-group xml:lang="en"><kwd>diabetes mellitus</kwd><kwd>ECG</kwd><kwd>QT</kwd><kwd>QT</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сахарный диабет</kwd><kwd>ЭКГ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Thordarson H., Sovik O.
