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.

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?

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.
