    OK, how did you go team?

    ST elevation in aVR and V1 has high specificity and sensitivity for the LMCA or proximal LAD occlusion.
    Additionally, STE in aVR > STE in V1 has high specificity for LMCA occlusion.
    STE in aVR > 1.5mm has mortality rate of 75%!!!

    Aspirin and even the thromobolysis is ineffective.

    These patients needs to go to the cath lab for PCI/CABG!
