Wellens Syndrome


  • Wellens Syndrome = high grade LAD or LM coronary lesion


  • history of chest pain
  • chest pain with a normal looking ECG (pseudonormalisation)
  • minimally elevated cardiac enzymes
  • no pathological precordial Q waves or loss of R wave progression
  • pain free ST elevation in V2 and V3 (minimally elevated)
  • pain free symmetrical deep T wave inversion or biphasic T waves in V2-V5

Two types

Type A – 25%

  • pain free: biphasic T waves in the anterior leads
  • during pain: paradoxical pseudonormalisation of ST segments
  • needs to be recognized because it will cause anterior MI within 9 days (if not dealt to by PCI or CABG)

Type B – 75%

  • deep symmetrical T wave inversion in I and aVL
  • chest leads: 1mm of ST elevation
