Brugada syndrome

Abstract

First described in 1992, Brugada syndrome is characterized by a specific electrocardiographic pattern in the right precordial leads and susceptibility to ventricular arrhythmias and sudden death. Brugada syndrome is included among the channelopathies, primary electrical disorders that, characteristically, are not associated with concomitant structural cardiac abnormalities. In recent years, substantial preclinical and clinical research has led to the identification of multiple causative mutations and to understanding of the mechanisms underlying the development of the characteristic phenotype and of the factors that determine clinical prognosis in patients. Nevertheless, there remain numerous unresolved questions which provide an impetus for ongoing active research into the condition. This article provides a summary of what is currently known about Brugada syndrome and an overview of the principal preclinical and clinical studies that have made the most significant contributions to our understanding of the condition.
