Recurrent exercise-induced ventricular tachycardia in a patient with Brugada syndrome
HeartRhythm Case Reports(2021)
Abstract
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.
