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
