■ Figure 15-30 Lateral wall infarction. ST elevation is present in leads I and aVL with reciprocal depression
in inferior leads. The absence of ST elevation in V 4 and V 5 indicates that the high lateral wall is involved but
V
not the lower portion. R-wave progression is not normal in V 1 –V 3 , indicating potential anterior involvement.

■ Figure 15-31 (A) Acute anterolateral wall MI. ST elevation is present in leads I, aVL, and V 2 –V 6 . Recip-
V
rocal ST depression is present in leads III, aVF, and aVR. (B) Acute anterolateral MI. Dramatic ST elevation
V
in leads I, aVL, and V 2 –V 6 with equally dramatic reciprocal ST depression in inferior leads. This is sometime
called a “huge current of injury.”
