• 12-lead ECG there are no leads that face the posterior wall, and, therefore, no indicative changes are recorded. • reciprocal changes in the anterior leads, especially V1 and V2, but often all the way to V4. • taller R wave than normal V1 and V2 • ST-segment depression • upright, tall T waves

12 Lead ECGs: Ischemia, Injury, Infarction Page 12 of 90 Format of the Printed 12 Lead ECG The 12 Lead ECG has a standardized format. There are six Frontal Leads which are labeled or called Leads I, II, III, aVR, aVL, and aVF. Leads I, II, and III represent a picture of the heart’s electrical conduction from viewpoint of the limb to the heart.

Injury/Infarct Recognition • What to Look for: • ST segment elevation (≥1mm) • Present in two or more anatomically contiguous leads. A normal ECG does NOT rule out any Acute Coronary Syndrome.\爀屲ST segment depression represents ischemia, infarction is possibl\൥.\爀屲ST segment elevation represents epicardial ischemia, and is presumptive evidence of AMI.\爀屲Since necrosis may ...
