Pericarditis

A pt in the 60's with hx of DM and HTN is complaining of chest pain. 

What do you think of the 12L?

The 12L showed sinus rhythm with what looked like ST elevations in limb leads and precordial leads.

Heat cath showed mild, non-obstructive CAD.

Going back to the 12L, the  PR depressions  in I, II, aVF and lateral leads created what it looked like an STE. There is also PR elevation in aVR. 

Those ECG changes were due to pericarditis.
