There is no definite evidence of acute ischemia. (ie, 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. Both episodes are initiated by an "R-on-T" phenomenon.

Such findings would normally suggest primary ischemia with concomitant surveillance of coronary occlusion, but these ST/T changes might very well be secondary to the Escape mechanism at hand. Lead V2 shows RR’ QRS configuration, and although ST depression is otherwise expected here, the discordance is a bit excessive. 2] Meyers, H.

This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. CMAJ 2017 Vassallo SU, Delaney KA, Hoffman RS, et al. What do you think?

There is ST elevation in 9/12 leads with ST depression only seen in lead aVR>V1 ( ie, virtually the opposite of what is seen with diffuse subendocardial ischemia in which there is diffuse ST depression except for ST elevation in aVR>V1 ).
