It has been estimated that in the aggregate, they occur at a rate of about 3 per 1000 patients with acute MI, and most of these events occur in patients with STEMI. A mong patients with STEMI, ventricular septal rupture is the most common and free wall rupture is the least common.

These elevations meet STEMI criteria ( ≥ 1mm in 2 contiguous leads). While this may be change that is reciprocal to an Acute/Subacute Inferior STEMI, the problem is that LV aneurysm may also manifest with this reciprocal change. In STEMI, they are generally upright and large in proportion to the QRS. This case is tough.
