The Brugada Electrocardiogram
Electrocardiogram (ECG) characteristics of Brugada pattern include coved ST segment elevation that is gradually descending in leads V1-V3 with either a true right bundle branch block or a pseudo-right bundle branch block pattern.
A Brugada pattern can be transient and may be unmasked by anesthetic agents such as lidocaine or propofol, sodium channel blockers, class I antiarrhythmic agents such as procainamide or flecainide, tricyclic agents, cocaine, right ventricular ischemia, or pulmonary embolism. The prevalence of Brugada pattern on an ECG in an asymptomatic individual is estimated to be 0.01% to 0.1%. A type 2 or type 3 Brugada pattern that is asymptomatic does not generally require any specific work-up and is a considered normal variant.1,2
