Post cath ECG: Now there are hyperacute T-waves again, and recurrent ST depression in V2 This ECG would normally diagnostic of OMI until proven otherwise No further troponins were measured, but it looks like there is recurrent OMI Next day: A CT Coronary Angiogram was done (CTCA) CARDIAC MORPHOLOGY AND FUNCTION: 1. Circulation.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

We know, stress tests can give false positive results suggesting ischemia in at least 20% of patients for various reasons. Mostly, you can’t escape from a coronary angiogram” Next option is CT angiogram, Thallium or dobutamine stress. The patient seeked by advice “It was indeed an academic stress test.

The patient was started on heparin for possible NSTEMI vs demand ischemia. increasing stenosis, ischemia, volume changes, increased blood pressure, atrial fibrillation, etc.) The EKGs from the ED presentation were felt by cardiology to represent "subendocardial ischemia." Smith : these ECGs do NOT show subendocardial ischemia.

That said there were no clinical symptoms or ECG findings suggestive of ongoing ischemia. CT coronary angiogram showed a hypoplastic RCA and dominant LCx. You have given IV MgSO4 a fast acting -blocker and IV amiodarone bolus and infusion. Troponin T was negative on admission and on repeat blood draw. No PVCs are seen.
