Implication

ECG sex differences observed in young adults; hypothesis-generating for sex-specific norms but should not yet change practice.

Key Points

Determine the influence of biological sex on resting 12-lead electrocardiographic parameters in young adult athletes and sedentary controls.
Evaluated resting 12-lead electrocardiograms in a cohort of 1,450 young adults stratified by sex into 617 females and 833 males.
The sample comprised 1,299 physical education and sports students alongside 151 age- and sex-matched sedentary control subjects.
Females showed significantly higher heart rates, shorter conduction intervals (PQ, QRS, and ventricular activation time), prolonged repolarization (QTc), and reduced P, Q, and T amplitudes and hypertrophy indices compared to males (p < 0.0001 for nearly all parameters).
First-degree AV block occurred in 1% of females versus 3% of males (p < 0.02), while incomplete right bundle branch block and R/S notching in V1-V2 were significantly less frequent in females (p < 0.0001).
Sex-related differences in electrocardiographic measurements remained consistent when evaluating the athletic cohort and sedentary control group independently.

Population

1,450 young adult subjects, comprising 1,299 students of physical education and sports and 151 age- and sex-matched sedentary controls (617 females and 833 males)

Intervention

Female sex

Comparator

Male sex

Outcome

Resting 12-lead electrocardiogram parameterssurrogate

Gender significantly influences resting ECG parameters, suggesting the need for sex-specific upper normal limits.
