%X 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¡À3.1 years in patients and 10.0¡À5.1 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¡À0.062 vs. 0.32¡À0.071,P=0.007). T-peak-to-T-end interval dispersion was significantly greater in the group of patients (0.15¡À0.07 vs.0.11¡À0.04, P¡À0.003).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.
