| Popis: | The goal of this search was to find out whether the sensitivity of QT interval, QT dispersion (QTd), corrected QT (QTc) interval and corrected QT dispersion (QTcd) sensitivity in the early diagnosis of ventricular arrhythmia and cardiovascular mortality in normotensive exists or not and to evaluate their relation to the parameters examined in terms of cardiovascular complications, such as body mass index (BMI) and finally if there is a significant relationship in between, to draw attention to the risk of serious ventricular arrhythmia in this group of children. Method: 30 obese children who were followed up with exogenous obesity at the Department of Pediatric Endocrinology and 20 healthy children who came to the Pediatric Cardiology Polyclinic with the preliminary diagnosis of innocent murmur were included in the study. Fasting serum lipids, glucose and insulin levels were examined in all children through anthropometric and blood pressure measurements. Electrocardiographic recordings were obtained and QT interval, QT dispersion, QTc interval and QTc dispersion were calculated. The apical widths in the apical four cavity positions were evaluated with two-dimensional and m-mode echocardiography.Results: QT interval, QT dispersion (QTd), corrected QT (QTc) interval and corrected QT dispersion (QTcd) obtained from ECG recordings in the early diagnosis of ventricular arrhythmia and cardiovascular mortality were higher in the patient group, but no statistically meaningful difference was found when compared to the control group. There was no positive correlation between these values related to QT interval and blood lipids and serum insulin levels which were examined in terms of body mass index and cardiovascular complications. However, increased left ventricular mass, body mass index, left ventricular mass index and m-mode echocardiographic measurements showed positive correlation as expected. Conclusion: There is no risk of severe ventricular arrhythmia in normotensive children diagnosed with exogenous obesity as it is in adults. However, this group of children should be closely monitored for serious rhythm disorders that will occur later in life and care should be taken for potential complications. |
