11.4 Brugada syndrome. National registry of Cuba 2003

Abstract

Methods: Brugada-type ECG in healthy men included in the Quebec Cardiovascular Study was assessed by systematic review of all (4374 men, 46±8 years old) ECGs done between 1974 and 1985. Classification of BS was made according to three different repolarization patterns: Type 1 is characterized by a coved ST-SE ≥2mm followed by a negative T-wave. Type 2 represents a high take-off ST-SE (≥2mm) with a descending ST-SE (remaining ≥1mm above the baseline) followed by a positive T-wave. Type 3 shows a right precordial ST-SE <1mm.
