ABSTRACT
The use of high right precordial (HPL) leads to "unmask" Brugada syndrome (BrS) has been described by some groups. We report a family with three cases of BrS. In two, HPL were obtained by placing V1 to V3 electrodes on the first, second, and third right parasternal spaces, and V4 to V6 on the first, second, and third left parasternal spaces. A control group of 45 subjects without BrS was also studied. Compared with standard V1 and V2 leads, the abnormal repolarization pattern of the BrS was accentuated only in the BrS cases using HPL. In none of the control subjects alterations of the J point or ST segment were observed in HPL. These observations exemplify the relevance of HPL for the diagnosis of the BrS.
