The Fragmented QRS Complex in Lead V₁: Time for an Update of the Athlete's ECG?

ABSTRACT: Differentiating between ECG patterns related to athletes' heart remodeling and pathological findings is a challenge in sports cardiology. As the significance of fragmented complex in athletes remains uncertain, this study aimed to assess the presence of fragmented QRS in lead V₁ (fQRSV₁) among young athletes and its association with heart adaptations and arrhythmias. Young athletes referred for annual pre-participation screening receiving a maximal exercise testing and transthoracic echocardiography from January 2015 to March 2021 were included. The study included 684 young athletes. The prevalence of fQRSV₁ was 33%. Subjects with fQRSV₁ had higher exercise capacity and indexes of right ventricular function and remodeling. Among highly trained at
