He presented to the Emergency Department with a blood pressure of 111/66 and a pulse of 117. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. Then ACS (STEMI) might be primary; this might be cardiogenic shock. He had this ECG recorded. Are the lungs clear?

Because of the tachcardia, I would expect her to be very poor left ventricular function and maybe Cardiogenic shock. Still Irregular Blood pressure during these rhythms was adequate; there was no shock. Old MI with persistent ST Elevation (LV aneurysm morphology) can look like acute MI 2. LV Aneurysm?

Her blood pressure on arrival was 153/69. There are no Q-waves to suggest old inferior MI, or inferior aneurysm as the etiology of the ST Elevation. Whenever there is tachycardia, I am skeptical of OMI unless it has led to severely compromised ejection fracction with cardiogenic shock.
