Diagnosis and Analysis

OK !! I agree this is only 6 of 12 leads. So what do you think our patient is experiencing?? Well, we know that leads I-AVF, are all limb leads. We also know that leads : I and AVL view the lateral wall of the left ventricle. Leads II, III, and AVF view the inferior aspect of the left ventricle. Notice the ST elevation in leads II, III, & AVF, this is indicative of an inferior MI. You may also have reciprocal changes, as evidenced here with the ST depression in leads I & AVL. This is usually associated with occlusion of the right coronary artery, as is evidenced by her angiogram.
