The causes of an anterolateral infarct of undetermined age are similar to those of other myocardial infarctions and include:
Troponin levels are essential to distinguish between acute myocardial injury and chronic scar.
This paper aims to demystify this ECG finding by analyzing the electrophysiological mechanisms behind Q-wave formation, distinguishing true infarction from anatomical and physiological mimics, and outlining a rational approach to patient management.
