  • QRS > 0.12 in limb leads
  • Triphasic QRS (rSR') or biphasic (qR), often with ST depression & TWI in V1-V3
    • V1 must have a positive complex
    • ST depression and TWI in other leads should arouse suspicion
  • Slurred S in 1 and V6
  • Any ST elevation is abnormal in RBBB and must prompt evaluation for STEMI
