II. Epidemiology

  1. De Winter T Waves are seen in 2% of Left Anterior Descending coronary lesions

III. Criteria

  1. Hyperacute T Waves with J Point Depression
    1. J Point depression with upsloping ST Segment AND
    2. Tall, prominent, hyperacute precordial T Waves
  2. Other findings
    1. No ST Segment Elevation in precordial leads
    2. ST Segment Elevation in aVR

IV. Interpretation

  1. Hyperacute T Waves with J Point Depression suggests acute Occlusion of the LAD Coronary Artery

V. Differential Diagnosis

  1. See Hyperacute T Wave
  2. Hyperkalemia
  3. ST Elevation Myocardial Infarction (STEMI)
    1. T Wave widens with increased height as an early change in STEMI, often prior to ST Elevation
