Does anabolic androgenic steroid use alter cardiac repolarization parameters in exercising men?
Population
22 men who regularly engaged in both resistance and aerobic exercise at fitness academies (n=22)
Comparison

AAS-associated QTc/QTd increases may signal arrhythmia vulnerability; leaves open prospective validation in longitudinal cohorts.
Does anabolic androgenic steroid use alter cardiac repolarization parameters in exercising men?
Anabolic androgenic steroid abuse is associated with increased QTc interval and dispersion, indicating abnormal ventricular repolarization that may elevate the risk of arrhythmias.
Maior et al. (2010) studied this question.
