ST depression in V1 - V4 suggestive of Ateroseptal Ischemia with lower lateral STEMI (partial occlusion of the LAD with a total occlusion of a diagonal branch)vs. Reciprocal changes to a posterior STEMI in V1 - V4 with lateral extension (LCX occlusion with left dominance. The axis has changed, but is still normal @ 40-50*. Either way, it's still a Cathlab Team Alert. Very good 12 lead. Question: Why did the lateral STEMI NOT produce reciprocal changes in the Inferior leads?N.

The second strip is clearly inferior lateral wall MI with recipricol changes in V-2 and V-3. Cool strips.Call the cardiac alert.Terrynoreply@blogger.com
