This is an ECG from a 95 year old man who was recovering from an anterior-septal wall M.I. Other clinical data for this patient has been lost, except that he suffered a new right bundle branch block during this M.I. The ECG shows pathological Q waves in V1, V2, and V3, consistent with permanent damage (necrosis) in the anterior septal wall. The ST segments in those leads are coved upward. Even though the J points are not elevated, this ST segment shape suggests recent injury.
