Should ECG criteria for Low QRS voltage (LQRSV) be specific for Sex?
Authors' conclusion
LQRSV is more common among female athletes than male athletes using established criteria.
Study context
- Population
- Young athletes (14–35 years) undergoing mass ECG screening at multiple US sites, 2014–20218,679 analysed
- Participants
- 10,728 athletes
- Exposure
- Male vs female athletes
- Outcome
- Prevalence of LQRSV by established criteria, stratified by sex

Main finding
As reported in the abstract
LQRSV (Sokolow-Lyon Index)
P < 0.001
- LQRSV prevalence by traditional limb lead or precordial lead criteria significantly lower in males than females
- P < 0.001
Observational data: associations, not effects.
Further findings
- Applying first percentile for LQRS amplitude criteria provided possible values for screening young athletes for LQRSV
