The presence of fQRS is often noted in pre-participation screening of athletes. In this study, we aimed to investigate the prevalence and clinical significance of fQRS in a cohort of ostensibly fit veteran athletes (VA). Methods We recruited 314 predominantly Caucasian VA's with a history of endurance exercise and no traditional risk factors for coronary artery disease. Participants underwent a 12-lead electrocardiogram, cardiopulmonary exercise testing (CPET), 24-hour Holter monitoring, and cardiac magnetic resonance imaging (CMR). fQRS was categorized as >2 consecutive leads using established criteria (1). Results fQRS in 2 or more contiguous leads was identified in 12% of VA's. The presence of fQRS was more prevalent in males and increased with age (p < ...

We aimed to assess the prevalence and significance of de-novo ECG changes following COVID-19 infection.MethodsIn this multicentre observational study, between March 2020 and May 2022, we evaluated consecutive athletes with COVID-19 infection. Athletes exhibiting de-novo ECG changes underwent cardiovascular magnetic resonance (CMR) scans. One club mandated CMR scans for all players (n=30) following COVID-19 infection, despite the absence of cardiac symptoms or de-novo ECG changes.Results511 soccer players (median age 21 years, IQR 18–26 years) were included. 17 (3%) athletes demonstrated de-novo ECG changes, which included reduction in T-wave amplitude in the inferior and lateral leads (n=5), inferior leads (n=4) and lateral leads (n=4); inferior T-wave inversion (n=7); and ST-segment depression (n=2). 15 (88%) athletes with de...
