Overview
Patients with Brugada syndrome will sometimes have a family history of sudden cardiac death, syncope, seizures, Agonal breathing all of which may come on at rest or during sleep.
History
- Brugada syndrome is diagnosed when a Type 1 ST-segment elevation is observed in more than one right precordial lead (V1-V3), in the presence or absence of sodium channel blocking agent, in conjunction with one or more of the following:
- 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.
Symptoms
These complications typically occur when an affected person is resting or asleep:
