Pathophysiology
- Genetically-linked Na channelopathy
- Incomplete RBBB with ST elevation in V1-V3
- Increased risk of sudden cardiac death
- ~10%/yr
- Much more common in men (up to 9x)
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
Disposition
- Pts need an AICD
