Subendocardial Ischemia from another Cause ( ie, sustained tachyarrhythmia; cardiac arrest; shock or profound hypotension; GI bleeding; anemia; "sick patient" , etc. ). The January 9, 2019 post in Dr. Smith's ECG Blog ( Please scroll down to the bottom of the page to see My Comment ).

A prehospital ECG was recorded (not shown and not seen by me) which was worrisome for STEMI. A previous ECG from 4 years prior was normal: This looks like an anterior STEMI, but it is complicated by tachycardia (which can greatly elevate ST segments) and by the presentation which is of fever and sepsis.

It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. Then they did an MRI: Patient underwent cardiac MRI on 10/4 that showed mildly reduced BiV systolic function. This has resulted in an under-representation of STEMI MINOCA patients in the literature.

A patient had a cardiac arrest with ventricular fibrillation and was successfully defibrillated. COACT: The COACT trial was fatally flawed, and because of it, many cardiologists are convinced that if there are no STEMI criteria, the patient does not need to go to the cath lab. These studies did not address OMI ECG findings!!!

But limitation of this ST elevation to a single lead is not consistent with any distribution of a STEMI. Unfortunately — the patient abruptly developed hypoxemia, followed by cardiac arrest with PEA. It was thought that this action precipitated the patient's desaturation, and led to his cardiac arrest.

If it is STEMI, it would have to be RBBB with STEMI. This ECG pattern may be diagnostic of B rugada S yndrome IF seen in association with: i ) a history of cardiac arrest; polymorphic VT; or of non-vagal syncope; and / or ii ) a positive family history of sudden death at an early age; and / or iii ) a similar ECG in relatives.

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.

The paramedics diagnosis was "Possible Anterolateral STEMI." More proof that a huge STEMI may have normal or near normal initial troponin.
