Key result
Exercise linked to recurrent VT in a patient with Brugada syndrome.
Why the study?
The relation of monomorphic VT to exercise in Brugada syndrome remains unknown, resulting in limited recommendations regarding exercise restriction.
Case Report (n=1)
Highlights a rare presentation of exercise-induced ventricular tachycardia in a patient with Brugada syndrome, providing evidence that may challenge current exercise restriction guidelines.
Highlights potential exercise-related VT risk in Brugada syndrome; hypothesis-generating and requires larger studies before guiding practice.
Brugada syndrome (BS) is an inherited arrhythmia syndrome with an increased risk of sudden cardiac death.1 Polymorphic ventricular tachycardia (VT) triggered by high vagal tone, particularly during sleep, is considered the primary mechanism of sudden death in these patients. Although some BS patients may present with monomorphic VT, its relation to exercise remains unknown.2 Accordingly, there are limited recommendations to restrict exercise in BS owing to lack of evidence of provocation of ventricular arrhythmia by exercise.

Powers et al. (2020) conducted a case report in Brugada syndrome (n=1). Exercise was evaluated on Ventricular tachycardia. Exercise induced recurrent ventricular tachycardia in a patient with Brugada syndrome.
