Answer for November 9, 2012
The EKG demonstrates an acute antero-lateral ST elevation MI. Note the straightening of the ST segment in V2 and the upward bowing and ST segment elevation across the rest of the precordium. This is likely an LAD occlusion. Also note the Tw inversions inferiorly. These are likely so-called 'reciprocal change'. When ST elevation MI occurs in lateral leads, the inferior wall typically shows these changes. Conversely when the inferior wall is involved in an STEMI, the lateral leads may show Tw inversion and even ST depression. These are usually not ischemic.
