who presented to a cardiologist with an ECG that showed a normal sinus rhythm with T wave inversions across the anterolateral precordial leads of uncertain nature. Subsequent examinations by his general practitioner, such as exercise stress testing and echocardiography, showed inducible silent myocardial ischemia and the

rent ischemia of the anterolateral and the inferior myocardium. In the case of anterolateral STEMI, we hypothesize that an ischemic vector directed toward the inferior myocardium may attenuate the ischemic vector directed toward lead aVL. Hence, it is possible that absence of STE in lead aVL represents either proximal occlusion of a

Subendocardial ischemia • The subendocardium is particularly vulnerable to ischemia because it is most distant from the coronary blood supply and closest to the high pressure of the ventricular cavity. • ST segment depression is the most common ECG change

2. Correctly identify the following normal ECG components: isoelectric line, Q wave, R wave, and ST segment. 3. Describe the ECG characteristics of a normal 12 lead ECG. 4. Systematically assess and interpret a 12 lead ECG for abnormal patterns of ischemia, injury, and infarction. 5. Interpret ST elevation MI (STEMI or acute injury changes). 6.

• ECG is the mainstay of diagnosing STEMI which is a true medical emergency • Making the correct diagnosis promptly is life-saving • If the clinical picture is consistent with MI and the ECG is not diagnostic serial ECG at 5-10 min intervals • Several conditions can be associated with ST elevation
