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 …

For descriptive purposes, ECG abnormalities were grouped according to location of the abnormality as anterior (leads V1–V4), anterolateral (leads V5–V6), lateral (leads I, aVL), or inferior (leads II, III, aVF).

This phenomenon of altered T-wave polarity (originally referred to as ‘post-tachycardia T-wave changes’) was described in patients with ventricular tachyarrhythmias as early as 1940’s, but Rosenbaum et al. first coined the term ‘cardiac or T-wave memory’ in …
