Hypothesis-generating for unipolar leads in pediatric hypertrophy assessment; prospective validation needed before clinical adoption.
Does unipolar lead electrocardiography improve the reliability of criteria for hypertrophy compared to standard electrocardiography in infants and children?
Unipolar lead electrocardiography provides more reliable criteria for ventricular hypertrophy in children than standard electrocardiography.
