Echocardiogram Physiology STEMI

SCM may happen from a wide variety of psychological or physiological stresses, including respiratory failure (although in this case a psychological stress led to poor myocardial function and then pulmonary edema, then respiratory failure) and intracranial bleeding. In this case, the ECG never mimicked a STEMI.

This appears to be new, as her last formal echocardiogram 2 years ago was relatively normal. Patients like her are the reason we are advocating for a change in the ACS paradigm from STEMI to OMI. For some reason (with debatable physiology), coronary occlusion often causes decrease in the high voltage of LVH on the EKG.

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. Look at the aortic outflow tract. What do you see?

Next day echocardiogram showed inferolateral hypokinesia with an EF of %45-50. On echocardiogram you will not see a "posterior" hypokinesia (will see "inferolateral") and, as in this case, LCx may not give the blood supply of basal inferior segment (formerly called "posterior"). The patient recovered well.

Not quite a STEMI, but same effect.) There is ST elevation in V2-V4 that does not quite meet "STEMI criteria." That is a reasonable thought, but we have shown that if there is one lead of V1-V4 with a T/QRS ratio greater than 0.36, then it is STEMI, not LV aneurysm. Is this a transient STEMI? Is it normal ST elevation?
