Prolonged QT dispersion is associated with pediatric syncope. Turk J Pediatr 2019; 61: 85-91. We aimed to find out whether QT dispersion can be used as a diagnostic marker in terms of syncope type, and recurrence risk. Fifty-two patients (28 male, 53.8%) admitted to the pediatric cardiology clinic with syncope were compared with 50 healthy controls (28 male, 56%; mean age: 13.8±2.3 years, range: 11-17 years) for QT dispersion (QTd) and other electrocardiographic findings. Gender, age, echocardiography, blood pressure while standing and sitting, electrolyte levels, liver and kidney function tests, and QTd and QTcd (calculated with corrected QT: QTc) in electrocardiography (ECG) of patients were all evaluated. Patients` ages varied between 7-17 years and the mean age at first syncope was 13.9±2.4 years. Mean follow-up duration of the patients was 10±5 months (range: 5-18 months). Mean number of syncope attacks was 2.8±2.2. QTd (72±46 ms vs. 34±14 ms) and QTcd (77±45 ms vs. 33±14 ms) values of the patients were significantly longer, compared to control group (p < 0.001). The age, gender, QTd, and QTcd values did not differ between the subt...
