Brugada Syndrome in Puerto Rico: a Case Series
Abstract:
Brugada syndrome (BrS) is characterized by ST-segment changes in the right precordial ECG leads and a high incidence of sudden death in patients with structurally normal hearts. Life-threatening ventricular arrhythmias are the hallmark of Brugada syndrome. The incidence and prevalence of BrS in Puerto Rico, to our knowledge, has never been studied and there is only one case report of BrS in Puerto Rico in the literature [1]. We present 3 cases of BrS in Puerto Rican patients who presented to our institution with syncope and review the literature.
