Key result
In healthy school-age children, the mean corrected QT interval was 436.5 ± 23.8 ms (Bazzet) and 404.3 ± 19.4 ms (Fridericia), with no significant difference between sexes.
Why the study?
What are the normal values for electrocardiographic and vectorcardiographic descriptors of ventricular repolarization in healthy school-age children?
Population
646 healthy school-age children (348 males/298 females, mean age 8.54 ± 1.86 years)
Design
Cross-sectional

What are the normal values for electrocardiographic and vectorcardiographic descriptors of ventricular repolarization in healthy school-age children?
This study establishes a reference range of normal electrocardiographic and vectorcardiographic descriptors of ventricular repolarization in healthy school-age children.
Dilaveris et al. (2011) conducted a cross-sectional in Healthy (n=646). Male sex vs. Female sex was evaluated on Rate-corrected QT interval. In healthy school-age children, the mean corrected QT interval was 436.5 ± 23.8 ms (Bazzet) and 404.3 ± 19.4 ms (Fridericia), with no significant difference between sexes.
