A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. The aortic valve in this example also had critical stenosis by Doppler The patient continued to be hemodynamically unstable with poor cardiac output and very high LV filling pressures.

There is profound LVH with anterolateral ST elevation and reciprocal ST depression in II, III, aVF, and ST depression in V5 and V6 that could all be secondary to LVH or could represent ischemia superimposed on the repolarization abnormalities of LVH: note that wherever there is ST depression, it is associated with a very high voltage R-wave.

Comparison Summary: ANTEROLATERAL ST CHANGES ARE NOW MORE PRONOUNCED, RATE DEPENDENT VS ISCHEMIC CHANGES Here is the Queen's diagnosis: The cath lab was activated: Culprit Lesion (s): Thrombotic 99% mid LAD stenosis with TIMI II flow Peak troponin not measured, unfortunately. So we don't have a good idea how large the final infarct size was.

Again, it is common to have an ECG that shows apparent subendocardial ischemia after resuscitation from cardiac arrest, after defibrillation, and after cardioversion. and repeat the ECG, to see if the apparent ischemia persists. A third ECG was done about 25 minutes after the first: This shows resolution of all apparent ischemia.

It should be known that each category can easily manifest the generic subendocardial ischemia pattern. In general, subendocardial ischemia is a consequence of global supply-demand mismatch that usually ameliorates upon addressing, and mitigating, the underlying cause. What’s interesting is that the ECG can only detect ischemia.

She underwent exercise echocardiogram in mid October where she exercised for nearly 7 minutes on the standard Bruce protocol and had typical anginal pain and shortness of breath. Baseline echocardiogram showed moderate LV systolic dysfunction with no wall motion abnormalities. Lesion on Dist RCA: 90% stenosis reduced to 0%.

For those who depend on echocardiogram to confirm the ECG findings of ischemia, this should be sobering. In this case, the duration of ischemia was so brief that there was no such evolution, and there was near-normalization. Ischemia may be so brief that Wellens' waves do not evolve 3. The peak troponin I was 0.364 ng/ml.
