Key Points

To evaluate the influence of age, sex, and body habitus on the mean QRS electrical axis in order to establish robust normative reference standards for older children and adolescents.
Calculated the frontal plane mean QRS electrical axis from standard electrocardiographic limb leads in a pediatric and adolescent cohort.
Assessed distribution patterns and deviations across demographic and physical parameters, specifically age, sex, and body habitus.
Prior reference values for frontal plane electrical axis in older children and adolescents were identified as statistically inadequate due to insufficient sample sizes.
Establishes a biometric framework to define normative limits of electrical force orientation, enabling reliable differentiation between physiological variation and pathological axis deviation.
