State of myocardial de- and repolarization in children with minor developmental anomalies of the atroventricular and aortic heart valves
Abstract
152 people aged 6-17 years were examined to determine the state of myocardial de- and repolarization in school-age children with mitral valve and bicuspid aorta prolapse, which are the most common minor anomalies of cardiac development among children. Mathematical and statistical analysis of QTc, QTc max, QT c min, dQTc indicators was carried out on 12 standard ECGs of children. Although changes in both groups were less significant in young school-age children, in children 12–17 years of age with mitral valve prolapse, dQT fluctuations were noticeable due to unequal increases in QTmax and QTmi
