Rhythm

  • P wave upright in I, II, AVF
  • PR interval > 0.12

Rate

  • 300,150,100,75, 60, 50

Axis

  • QRS upright in I and aVF
  • If not upright in aVF look @ II
    • If upright then axis is normal
    • If not then there is left axis deviation

Intervals

  • PR 0.12-0.20 (3-5 squares)
  • QRS < 0.10 (2.5 square)
  • QT <0.44 (11 squares)

Atrial enlargement

  • Right atrium - lead II - p wave wave's initial component is enlarged, taller 2.5mm
  • Left atrium - Lead V1 - p wave downward deflection of terminal component

Ventricular hypertrophy

  • Right ventrical - tall R waves in V1 and V2, deep S in V6
  • Left ventrical - tall R wave in V6, deep S in V1, plus one of
    • R in V5 or V6 > 35 mm
    • R in aVL > 11mm
    • R in I > 15mm
