The Brugada syndrome is a clinical-electrocardiographic diagnosis characterized by syncopal episodes or sudden death (caused by ventricular tachycardia and ventricular fibrillation) in patients with a structurally normal heart with a characteristic electrocardiographic pattern consisting of ST segment elevation in precordial leads (Vl-V3) and a morphology of the QRS complex resembling right bundle branch block (the latter can transiently disappear). Timely diagnosis and adequate treatment may essentially decrease mortality of this disease.
