  30. LVH
    • Any precordial lead is > 45mm
    • The R wave in aVL is > 11mm
    • The R wave in lead I is > 12mm
    • The R wave in lead aVF is > 20mm
  31. The 3 Major criteria for RBBB are:
    • QRS > 0.12 seconds
    • Slurred S wave in leads I and V6
    • RSR' pattern in V1
  32. Three Major criteria for LBBB
    • Duration > 0.12 seconds
    • Broad, monomorphic R waves in I and V6 with no Q waves
    • Broad, monomorphic S waves in V1; may have a small r wave
  33. Criteria for Dx LAH
    • left axis deviation c the axis at -30o to -90o
    • either a qR complex or an R wave in lead I
    • an rS complex in lead III, and probably also in II and aVF
  34. Criteria for diagnosing LPH
    • an axis of 90 to 180o (the right quadrant)
