Brugada syndrome presenting with sustained monomorphic ventricular tachycardia.

Typically Brugada syndrome presents with either ventricular fibrillation or polymorphic ventricular tachycardia that may result in sudden death or syncope in patients without any structural heart disease. We report the case of a patient with Brugada syndrome who presented atypically with recurrent presyncope following physical exertion due to sustained monomorphic ventricular tachycardia, which appeared to be sensitive to both adenosine and catecholamine. He refused ICD implantation but remained asymptomatic on treatment with a beta-blocker.
