ECG MI 5


Answer

Culprit lesion: RCX

  1. sinus rhythm
  2. about 60/min
  3. normal conduction
  4. intermediate axis
  5. normal p wave morphology
  6. No pathologic Q or LVH. Tall R in V2, V3.
  7. ST depression in V2, V3. Also depression in III and AVF. Some elevation in I and AVL.
  • Conclusion: Postero-lateral MI caused by an RCX occlusion.

Note! The high frequency vibration that is most clearly seen in lead AVR (with a frequency of > 300/min) is an artefact and not a suprvaventricular tachycardia. In SVT, there would be no P waves.

It is quite unusual that lead III shows depression in a RCX infarction. Apparently the inferior part is not much affected by this infarction.
