Abstract

 Objective: The purpose of this study was to examine the relationship between T-peak-to-T-end interval and its dispersion in children with SYNCOPE to detect possible repolarization abnormalities in these patients.Methods: We enrolled 19 patients with a positive tilt test for SYNCOPE (7 boys, 12 girls) and 35 participants with normal results on the test.Findings: Mean age was 11.4±3.1 years in patients and 10.0±5.1 years in controls (P=0.27). The T-peak-to-Tend interval in lead V1 was significantly longer in patients with a positive tilt test (0.36±0.062 vs.0.32±0.071, P=0.007). T-peak-to-T-end interval dispersion was significantly greater in the group of patients (0.15±0.07 vs. 0.11±0.04, P ±0.003).Conclusion: The T-peak-to-T-end interval in lead V1 and T-peak-to-T-end dispersion were significantly larger in patients with a positive tilt test. Our findings suggest a depolarization abnormality in children with SYNCOPE.
