Santini M, et al. - Researchers studied electrocardiographic (ECG) patterns and their link with anthropometric characteristics in twenty-four thousand and sixty-two students of Roman schools, aged 12–19. Electrocardiographic abnormalities were classified as either minor/non-clinically relevant or major, and anthropometric measures were evaluated per age class. Higher rate of obesity prevalence was noted in younger students. With increasing age, decrease in heart rate and QT interval corrected for heart rate (QTc) was observed. The QTc was found to be longer in females vs in males over 14 years. The most common major abnormality was right bundle branch block (RBBB), which was found to be related to higher stature.
