Is this new LAD occlusion with ST Elevation superimposed on old QS-wave MI?

This ECG is from a middle aged male who presented with a choking feeling in his throat, on a background of prior anterior STEMI complicated by cardiac arrest, and ICD.

This ECG shows QS waves with ST elevation in anterior leads. The T waves were larger than previous, so he was sent to the cath lab, but angiography was normal.

Two cases of ST Elevation with Terminal T-wave Inversion – do either, neither, or both need reperfusion?

This ECG is from a man of unknown age who had cardiac stents placed 2 months ago.

This ECG shows sinus rhythm with QS-waves and ST elevation in V1-V3, with some terminal T-wave inversion. Serial troponins and angiography was normal.
