T Wave

Aka: T Wave
  1. Findings: Normal
    1. Upright: I, II, V3, V4, V5, V6
    2. Inverted: aVR, V1
    3. Variable: all other leads
    4. Increased Amplitude: aVL and aVF (if QRS over 5 mm)
  2. Findings: T Wave Shape
    1. Smooth: Normal
    2. Notched: Pericarditis
    3. Pointed: Myocardial Infarction
  3. Findings: T Wave Height
    1. Normal
      1. Limb leads: <5 mm
      2. Precordial leads: < 10 mm
    2. Tall T Waves
      1. Hyperkalemia
      2. Myocardial Infarction
