Inferior Subtle ST elevation: straight ST segment, but also no reciprocal ST depression in aVL: which is more important?

This ECG is from a man in his 60s who presented with chest pain radiating to the back and nausea/vomiting. He had a history of previous MI and stents.

This ECG shows inferior ST elevation (straightened ST segments) without reciprocal changes, with terminal QRS distortion in inferior leads. The cause was an inferior MI with some posterior involvement.

A 50-something with chest pain presents to a Non-PCI capable facility

This ECG is from a man in his 50s who presented with chest pain.

This ECG shows subtle anterior ST elevation with fragmented QRS and straightened ST segment. The cause was an occluded LAD stent, along with 90% stenosis of RCA and 70% circumflex stenosis.

A Tale of 2 Occlusions in the Same Patient: one with Expert ECG interpretation, the Other Without -fifth repeat ECG on day 2, after morphine

This ECG is from a man in his 40s who presented with chest discomfort and diaphoresis since waking a few hours earlier, on a background of prior infarction with PCI years ago, active smoking, high cholesterol and hypertension. This was the repeat ECG on day 2, after pain returned with nausea and diaphoresis that was exactly like his initial pain and did not resolve with morphine.
