Exercise stress testing unmasked ventricular tachycardia and near-syncope in an 18-year-old male with Brugada syndrome, suggesting a role for exercise testing in risk stratification.
Case Report (n=1)

This case highlights that exercise testing may have a potentially important role in diagnosing and risk stratifying certain patients with Brugada syndrome, challenging the notion that exercise is not a trigger for arrhythmias in this condition.
Brugada syndrome (BrS) is a hereditary condition that is characterized by ST elevation, ventricular tachycardia or fibrillation, and sudden cardiac death in otherwise healthy patients. Life-threatening arrhythmias generally occur, while at rest, with fever or during vagotonic states. Exercise is generally not considered a trigger for ventricular arrhythmias or syncope in patients with BrS. We describe a patient who presented with exercise-induced syncope, ventricular tachycardia during an exercise test, and was found to be both genotypically and phenotypically positive for BrS. This case highlights a potentially important role of exercise testing in diagnosing and risk stratifying certain patients with BrS.
Batra et al. (Tue,) conducted a case report in Brugada syndrome (n=1). Exercise stress testing was evaluated on Ventricular tachycardia and syncope during exercise. Exercise stress testing unmasked ventricular tachycardia and near-syncope in an 18-year-old male with Brugada syndrome, suggesting a role for exercise testing in risk stratification.
