## HRS/EHRA/APHRS Expert Consensus Diagnostic Criteria for Brugada Syndrome (2013)

1. Brugada syndrome is diagnosed in patients with ST-segment elevation with type 1 morphology > 2 mm in > 1 lead among the right precordial leads V1, V2, positioned in the 2nd, 3rd, or 4th intercostal space occurring either spontaneously or after provocative drug test with intravenous administration of Class I antiarrhythmic drugs.
2. Brugada syndrome is diagnosed in patients with type 2 or type 3 ST-segment elevation with > 1 lead among the right precordial leads V1, V2, positioned in the 2nd, 3rd, or 4th intercostal space occurring when a provocative drug test with intravenous administration of Class I antiarrhythmic drugs induces a type 1 ECG morphology.
