Brugada syndrome.

Abstract

Brugada syndrome (BrS) is a cardiac channelopathy associated with an elevated risk of arrhythmias and sudden cardiac death compared with the general population. Since its initial description in 1992 by Pedro and Josep Brugada, there has been tremendous progress in our understanding and management of BrS. The condition is characterized by 'coved' ST segment elevations in the anterior precordial electrocardiogram leads, which occasionally requires additional pharmacological provocation for diagnosis. Substantial geographical variation in the prevalence, genetic characteristics and clinical behaviour of BrS exists. Improvements in the understanding of the genetic and molecular mechanisms of the condition have been made over the past 30 years, opening avenues for the discovery of diagnostic and management opportunities. In this Primer, we discuss the evolving epidemiology of BrS, the emerging genetic understanding of the condition, as well as its diagnosis and management. We summarize the major societal guideline recommendations pertaining to BrS and highlight the potential for technological advancements, such as digital health and machine learning, to improve patient care.
