ABSTRACT:
A method of differentiating between ischemic and cardiac memory inverted T-waves includes performing an electrocardiogram of a patient; identifying inverted T-waves in at least some of precordial leads; identifying T-waves in leads I and aVL; diagnosing ischemia if leads I and aVL show inverted T-waves; and diagnosing cardiac memory if the leads I and aVL show non-inverted T-waves. The method may also include identifying T-waves in lead III; confirming ischemic diagnosis if the lead III shows deeper inverted T-waves than in the precordial leads; and confirming cardiac memory diagnosis otherwise.
