There is no definite evidence of acute ischemia. (ie, Distinction of PMVT vs VFib is an academic one in this case ). Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( Some residual ischemia in the infarct border might still be present.

A combined effort from academic investigators, industry, and regulators is needed to improve imaging technologies and, ultimately, patient outcomes. Imaging in acute ischemic stroke treatment has advanced significantly, but important challenges remain that need to be addressed.

Most such rhythms in the setting of ischemia are VF and will not convert without defibrillation. This distinction is more than academic — because both treatment and the response to therapy tend to be different with these 2 entities. Acute ischemia?

So, we desperately required to break this inappropriate menace with evidence base like COURAGE, ISCHEMIA, BARI-2D, These studies tried to apply some breaks, but the force was weak and couldn’t abolish a pseudo-academic vice. There seems to be a non-academic indication for doing this study to undo the damage done by ORBITA-1.

There is probably a trickle of flow which is why there is both subendocardial ischemia (ST depression) and early subepicardial ischemia (hyperacute T-waves).

I do not think this ECG is by itself diagnostic of OMI (full thickness, subepicardial ischemia ), b ut comparison to a previous might reveal this ECG as diagnostic of OMI. Academic Emergency Medicine 27(S1): S220. Smith comment: There is a change in V2 as well, with less normal STE and a smaller T-wave with some inversion.

Traditional methods of non-invasive ischemia testing (stress EKG , stress echo, SPECT , PET , direct-to-cath) can result in false negatives 20-30 percent of the time, which can lead to undetected disease, and false positives over 50 percent of the time, which can lead to unnecessary invasive procedures.

It does not usually represent subendocardial ischemia, but rather it is usually reciprocal ST depression, reciprocal to inferior ST elevation.

The ECG is diagnostic of LAD occlusion (or even left main occlusion possibly), with the classic pattern of RBBB and LAFB with huge concordant STE in V1-V2, I, and aVL, with reciprocal depression in most other leads (and/or a component of subendocardial ischemia pattern).

This confirms that there were dynamic signs of ischemia on the initial ECG. In the interest of academic discussion — I’ll add the following thoughts: The computer interpretation was obviously wrong. Note that the ST elevation in the inferior leads has basically resolved, especially compared with the restored QRS voltage.

The diagnosis typically requires classic clinical features, with no evidence of obstructive coronary disease, and typical findings of ischemia on functional studies. This happens. But its rare!
