The VSR is what is causing the cardiogenic shock! Another possible cause of pseudonormalization of T waves mentioned many times on this blog is the pseudonormalization caused by re-occlusion of an infarct related reperfused coronary artery. Not all patients with acute ( or recent ) MI have chest pain with their event.

Case submitted by Rachel Plate MD, written by Pendell Meyers A man in his 70s presented with chest pain which had started acutely at rest and has lasted for 2 hours. The pain was still ongoing at arrival. He was in cardiogenic shock requiring an impella for several days after cath. But we should not be surprised.

He woke up alert and with chest pain which he also had experienced intermittently over the previous few days. The history in today's case with sudden loss of consciousness followed by chest pain is very suggestive of ACS and type I ischemia as the cause of the ECG changes. What do you think? This is an ominous sign.

The patient’s chest pain spontaneously resolved before he was evaluated and has a repeat ECG obtained at 22:12 obtained shown below. In context, of course, it is clear that the patient is reperfusing, as pain has dissipated and the diagnostic findings of OMI have become more nonspecific. This ECG is more difficult.

Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). But the History in today's case was acute shortness of breath with dizziness and lightheadedness — and, essentially without chest pain! Additionally, there is borderline right axis deviation.

This was my response: If it is the right clinical situation, such as acute chest discomfort, it looks like proximal left anterior descending occlusion with right bundle branch block and left anterior fascicular block.
