Brugada syndrome (BrS) is a genetic disorder marked by a characteristic electrocardiogram (ECG) pattern of ST-segment elevation and T-wave inversion in right precordial leads, which is associated with an increased risk of ventricular fibrillation in the absence of structural heart disease. Despite advancements in understanding its epidemiology, pathophysiology, and treatment, there is considerable variability in how sports cardiologists approach BrS. This expert opinion by the Italian Society of Sports Cardiology (SICSPORT) aim to review the current definition, diagnosis, epidemiology, genetics, risk stratification, and treatment of BrS and provide guidance for sport eligibility provides guidance for sports doctors and cardiologists in assessing competitive sports eligibility in athletes with BrS. A multiparametric approach to diagnosis and risk stratification is recommended, noting that the presence of a Brugada ECG pattern (BrP) does not confirm a BrS diagnosis. The risk of sudden cardiac death (SCD) is low in asymptomatic individuals with type 1 BrP, especially those with a drug-induced pattern. Pharmacological testing is not required for type 2 or 3 patterns without other risk factors. Low-risk individuals do not require therapy, while intermediate or high-risk patients may need pharmacological treatment, ICD implantation, or ablation. Asymptomatic individuals with type 2 or 3 BrP, no family history of SCD, and no other risk factors may be eligible for competitive sports, as well as asymptomatic type 1 BrP without risk factors and negative electrophysiological study. Conversely, sports eligibility should be denied in patients with BrS who have a history of syncope or cardiac arrest (high-risk subjects), regardless of ICD presence.
