Key result
Male athletes exhibited significantly greater QRS voltage for left ventricular hypertrophy and longer QRS duration, whereas female athletes had higher resting heart rates and longer QTc intervals.
Why the study?
Are there gender-related differences in training-related electrocardiographic patterns among athletes?
Population
315 athletes (150 males and 165 females, mean age 23.7±6.6 and 20.7±6.8, respectively)
Comparison
12-lead electrocardiogram vs Male versus female athletes

Gender differences in athletes' ECGs may inform sex-specific screening criteria; leaves open effects on false-positive rates or outcomes.

Significant gender-related differences exist in the ECGs of trained athletes, such as higher QTc and resting heart rates in females and higher QRS voltages and bradycardia in males, which should be considered during cardiovascular screening.
Om et al. (2018) conducted a cross-sectional in Healthy athletes (n=315). Male gender vs. Female gender was evaluated on QRS duration (ms) (p=<0.0001). Male athletes exhibited significantly greater QRS voltage for left ventricular hypertrophy and longer QRS duration, whereas female athletes had higher resting heart rates and longer QTc intervals.
