ECG changes are seen in anterior precordial leads V1-3, but are the mirror image of an anteroseptal MI: Increased R wave amplitude and duration (i.e., a "pathologic R wave" is a mirror image of a pathologic Q) R/S ratio in V1 or V2 > 1 (i.e., prominent anterior forces) up to 50% may also have a component of right ventricular infarction as well. Example #2: Anterior MI with bifascicular block (RBBB + LAFB). Note ST depression in leads Suggested ECG features, not all of which are specific for MI include: Reversal of the usual R wave progression in precordial leads (see above ). ST segment elevation in lead aVR that is greater than any ST segment elevation in lead V1 plus ST segment depression in Normal QRS intervals last 60 milliseconds to 100 milliseconds (1 ½ to 2 ½ small squares).

Evolving ST-T changes may include any of the following patterns: Convex downward ST segment depression only (common), Convex upwards or straight ST segment elevation only (uncommon), Symmetrical T wave inversion only (common), IHSS (septal hypertrophy may make normal septal Q waves "fatter" thereby mimicking pathologic Q waves), LVH (may have QS pattern or poor R wave progression in leads V1-3), RVH (tall R waves in V1 or V2 may mimic true posterior MI), Complete or incomplete LBBB (QS waves or poor R wave progression in leads V1-3), Pneumothorax (loss of right precordial R waves), Pulmonary emphysema and cor pulmonale (loss of R waves V1-3 and/or inferior Q waves with right axis deviation), Left anterior fascicular block (may see small q-waves in anterior chest leads), Acute pericarditis (the ST segment elevation may mimic acute transmural injury), Central nervous system disease (may mimic non-Q wave MI by causing diffuse ST-T wave changes), Normal variant (if the rest of the ECG is normal), LVH (look for voltage criteria and ST-T changes of LV "strain"), Complete or incomplete LBBB (increased QRS duration), Left anterior fascicular block (should see LAD in frontal plane), Emphysema and COPD (look for R/S ratio in V5-6 < 1), Diffuse infiltrative or myopathic processes, WPW preexcitation (look for delta waves, short PR), Normal variant (if rest of the ECG is normal), RVH (should see RAD in frontal plane and/or P-pulmonale), Complete or incomplete RBBB (look for rSR' in V1).
