Brugada syndrome

Background

• Consider as cause of syncope in pts w/ family history of sudden death
• Genetically-linked Na-channelopathy
• Increased risk of sudden cardiac death (~10%/yr)
• Much more common in men (up to 9x)
• ECG shows incomplete RBBB with ST elevation in V1-V3

ECG Criteria

• Note - ECG findings can be transient

• Type 1-Elevated ST segment (>2mm) descends w/ upward convexity to a TWI
• Type 2-Elevated ST segment (>1mm) descends toward baseline then rises again (saddleback) to upright T wave
• Type 3-Elevated ST segment (<1mm) descends toward baseline then rises again to upright T wave
