This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). Sinus tachycardia has many potential causes. This is especially true for the elderly patient with sinus tachycardia.

Because of the tachcardia, I would expect her to be very poor left ventricular function and maybe Cardiogenic shock. Alternatively , it is someone who has an old myocardial infarction and is now very sick with something else. Still Irregular Blood pressure during these rhythms was adequate; there was no shock.

There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. Here is that ECG: What do you think?

Authors' commentary: Cardiogenic shock in the setting of severe aortic stenosis. This patient’s severe aortic stenosis (AS) and associated severe cardiogenic shock likely created the ECG pattern, resulting in a very difficult challenge for our inpatient team. If you can use Doppler, then you can diagnose it.

The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. Troponin T peaked at 38,398 ng/L ( = a very large myocardial infarction, but not massive-- thanks to the pre-PCI spontaneous reperfusion, and rapid internvention!! ).
