GUEVARA-VALDIVIA, Milton E et al. Unmasking concealed Brugada syndrome through endovenous propafenone. Arch. Cardiol. Méx. [online]. 2002, vol.72, n.1, pp.45-48. ISSN 1665-1731.

We present the case of a woman with familial antecedents of a brother who died suddenly at the age of 39 years, and an other with Brugada syndrome. The ECG had not shown the typical pattern of the Brugada syndrome. Based on these antecedents, we decided to perform a pharmacological test with endovenous propafenone, which revealed the electrocardiographic alterations at 10 min after the administration. This is the first case in our knowledge in which endovenous propafenone manifested a concealed Brugada syndrome.
