MI 5

Culprit lesion: RCX

sinus rhythm
about 60/min
normal conduction
intermediate axis
normal p wave morphology
No pathologic Q or LVH. Tall R in V2, V3.
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.
