*type 1
+
Three ECG repolarization patterns in the right precordial leads are recognized in the diagnosis of Brugada syndrome.
*type 2
+
'''Type I''' is the only ECG criterium that is diagnostic of Brugada syndrome. Type I repolarization is characterized by a coved ST-segment elevation >=2 mm (0.2 mV) followed by a negative T wave (see figure). Brugada syndrome is definitively diagnosed when a type 1 ST-segment elevation is observed in >1 right precordial lead (V1 to V3) in the presence or absence of a sodium channel–blocking agent, and in conjunction with one of the following: documented ventricular fibrillation (VF), polymorphic ventricular tachycardia (VT), a family history of sudden cardiac death at <45 years old, coved-type ECGs in family members, inducibility of VT with programmed electrical stimulation, syncope, or nocturnal agonal respiration.
