Key result
Age, body surface area, and gender significantly influenced signal-averaged electrocardiography parameters, with only 0.6% of healthy children falling outside the newly established normal ranges.
Why the study?
How do age, body size, and gender influence signal-averaged electrocardiography (SAECG) parameters in healthy children?
Cross-Sectional (n=530)
How do age, body size, and gender influence signal-averaged electrocardiography (SAECG) parameters in healthy children?
Establishes normal ranges for SAECG parameters in children, highlighting the necessity of adjusting for age, body size, and gender during interpretation.
No takes yet. Share an insight, caveat, or question.
May warrant age-, BSA-, and gender-adjusted SAECG norms in children; leaves open prospective validation for clinical use.
Vaksmann et al. (1996) conducted a cross-sectional in Healthy children and adolescents (n=530). Age, body size, and gender was evaluated on Signal-averaged electrocardiography (SAECG) parameters including filtered QRS duration, RMS voltage, and LAS. Age, body surface area, and gender significantly influenced signal-averaged electrocardiography parameters, with only 0.6% of healthy children falling outside the newly established normal ranges.
