ECG pattern in Brugada syndrome. According to recent consensus document (ref 13), type 1 ST segment elevation either spontaneously present or induced with Ajmaline/Flecainide test is considered diagnostic. Type 1 and 2 may lead to suspicion but drug challenge is required for diagnosis. The ECGs in the right and left panels are from the same patient before (right panel, type 1) and after (left panel, type 1) endovenous administration of 1 mg/kg of Ajmaline during 10 minutes.
