Overview
The diagnosis of brugada syndrome is based upon electrocardiographic and clinical criteria.
Diagnostic criteria
- The presence of Type 1 ST-segment elevation in more than one right precordial lead (V1-V3). Type I ST elevation can be observed either spontaneously or following the administration of a sodium channel blocking agent.
- One or more of the following criteria must also be met:
- Family history of sudden cardiac death (SCD) (<45 years old)
- Documented ventricular fibrillation (VF)
- Polymorphic ventricular tachycardia
- Coved-type ECG changes in family members
- Inducibility of ventricular tachycardia (VT) with programmed electrical stimulation (PES)
- The diagnosis is also considered positive when a Type 2 (saddleback pattern) or Type 3 ST-segment elevation is observed in more than one right precordial lead under baseline conditions and can be converted to the diagnostic Type 1 pattern occurs upon exposure to a sodium channel blocker.
