Abstract

A method of differentiating between ischemic and cardiac memory inverted T-waves includes performing an electrocardiogram of a patient (702); identifying inverted T-waves in at least some of precordial leads (704); identifying T-waves in leads I and aVL (706); diagnosing ischemia if leads I and aVL show inverted T-waves (710); and diagnosing cardiac memory if the leads I and aVL show non-inverted T-waves (712). The method may also include identifying T-waves in lead III (714); confirming ischemic diagnosis if the lead III shows deeper inverted T-waves than in the precordial leads (724); and confirming cardiac memory diagnosis otherwise (720, 725).
