On an electrocardiogram (ECG), an anterior wall myocardial infarction is demonstrated on leads:
A. II, III, AVR
B. II, III, AVF
C. V1, V2, V3, V4
D. I, AVL, V5, V6
ANS: C
With angina and MI, acute ischemic changes may be seen on the 12-lead EKG. Each lead reflects an area of the heart, and an EKG can determine the location of the ischemia. The lateral wall of the heart is reflected in leads I, aVL, V5, and V6. The inferior wall is reflected in leads II, III, and a VF. The anterior wall is reflected in leads V1, V2, V3, and V4. The posterior wall is reflected in leads V1, V2, and V3. With ischemia, an EKG changes need to occur in two contiguous leads. Reciprocal EKG changes can be seen in the area of the heart opposite the injured area.
