The overall rhythm is chaotic — which is not necessarily unexpected given the history of an acutely ill 12-year with severe dilated cardiomyopathy on Echo. There definitel are periods of bradycardia (so pacing may be needed for that). Hope this helps — :) ECG-3 — I see sinus bradycardia and arrhythmia.

A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. An ECG machine is able to detect other abnormalities of the heart as well, such as hypertrophic cardiomyopathy or overly thick heart muscles.

As always, takotsubo cardiomyopathy and focal pericarditis can mimic OMI, but takotsubo almost never mimics posterior MI, and both are diagnoses of exclusion after a negative cath. STD maximal in V1-V4 (in this case V3-V4) is in my opinion the single best way to identify posterior OMI on the anterior 12 lead ECG. Were they right?

By ECG alone: it is suspicious for stress cardiomyopathy, or takotsubo, due to the diffuse ST Elevation: II, III, aVF AND I and aVL.
