Thus, this is both an anterior and inferior STEMI. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. Armstrong et al.)], the presence of such well developed anterior Q-wave suggests completed transmural STEMI. Could it be acute (vs.
