It would be inferior to not get this right.

Should be easy to see the inferior MI, but don't miss extension to right ventricle dx by:
- In the presence of inferior MI 
1) ST elevation in V1
2) ST elevation in lead III> II
3) ST elevation in V1 > V2
4) ST elevation V1 + St depression in V2 (highly specific for RV MI)
5) Isoelectric ST segment in V1 with marked ST depression in V2
