A male in his 40's who had been discharged 6 hours prior after stenting of an inferoposterior STEMI had sudden severe SOB at home 2 hours prior to calling 911. So it would be wise to look at the pre-discharge ECG, which was available: There are Q-waves and ST elevation on this pre-discharge (post-stent) ECG. He had no chest pain.

Although diagnostic of MI, it is highly suspicious for " Old inferior MI with persistent ST Elevation" or "inferior aneurysm morphology" because of the well-formed Q-waves and the flat T-waves. To repeat: in contrast, anterior aneurysm is much more easily distinguished from acute MI due to the QS-waves.

Old MI w/Aneurysm will show moderate ST Elevation, as seen here.
