Nursing Points

General

1. 12 Lead EKG: Injuries
   1. Inferior wall injury
      1. ST-elevation means injury has occurred (most times)
      2. ST depression means there is ischemia
   2. Anterior-septal wall injury
      1. V1, V2, V3
         1. No R wave present, likely previously infarcted (no ST elevation) or currently infarcting (ST elevation)
   3. When looking at EKG…
   4. First check inferior leads 2, 3, and aVF = look at inferior wall first
      1. 1. ST elevations seen
            1. Inferior wall MI
         2. ST depressions seen
            1. Inferior wall MI –> could be ischemia (ST depressions usually mean ischemia) or it is called reciprocal change
               1. Reciprocal changes should be gone in 24 hours–> if not than = ischemia
         3. Lateral wall MI
            1. ST elevation v5-v6
