Overview

The diagnosis of brugada syndrome is based upon electrocardiographic and clinical criteria. Only the Type I Brugada pattern qualifies as part of the diagnostic criteria for Brugada syndrome. Other rhythm abnormalities and family history are taken into account when making the diagnosis of Brugada syndrome.
