The pediatric team felt it might be ACS, but on review of his prior ECGs, it was thought to be really unchanged from the 2 prior and more consistent with myocarditis. The septum appears a bit darker than the rest, and you might be fooled into thinking there is ongoing ischemia here. See an examples of CT ischemia here.

In this pediatric study, it was 71% successful and better than amiodarone. Meyers, Smith; Weingart wrote an extensive review on Idiopathic VT in the September 14, 2018 post of Dr. Smith’s ECG Blog. Procainamide is another reasonable solution to the problem. As a result — it’s worth briefly reviewing this entity of “ Idiopathic ” VT.

Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). While today's case is the first we have published on cardiac sarcoidosis — we have featured infiltrative cardiomyopathy ( ie, with amyloidosis — in the November 15, 2020 post in Dr. Smith's ECG Blog ).

Pediatric and elderly patients were more predisposed to developing an arrhythmic event in the setting of fever [7]. Recently the rate of true arrhythmic events related to fevers in the classic Brugada Type 1 syndrome was explored by Michowitz et al. mm ( generally ≥2 mm ) in ≥1 right precordial lead, followed by a positive T-wave. —

I suspect most blog readers did not struggle with this one. Toward this end we've conveniently added a LINK for "LVH Criteria" in the Menu at the top of every page in Dr. Smith's ECG Blog. This ST-T wave pattern in lead V5 is not seen in other leads, as would be expected if this was truly a change of acute ischemia.
