Some computer-aided dispatch (CAD) software did better than others by considering the average travel time of an actual route instead of allowing nearness to be determined by a straight-line distance. It was a matter of determining which crew was available closest to the scene.

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. This was deemed “non-specific” by the ED physicians.

By Magnus Nossen This ECG is from a young man with no risk factors for CAD, he presented with chest pain. Before the lab values returned this patient had a n emergent coronary CT angiogram done that ruled out CAD. How would you assess this ECG? How confident are you in your assessment? What is your next step? at ~100/minute ).

My thought process in the moment was that leads aVL and V2 display an ST-segment that is “inappropriately baseline” – not elevated, by definition, but may very well be an equivalent of such as the ischemic zone is actively “pushing” them in an upward manner. It is accelerated angina, which is by definition not stable.

A followup ECG was recorded 2 days later: No definite evidence of infarction. Diagnosis of MINOCA should be made according to the Fourth Universal Definition of MI, in the absence of obstructive coronary artery disease (CAD) (no lesion ≥50%). In this case, profound shock for 1 hour would result in the same degree of infarction.

A man in his 70s with past medical history of hypertension, dyslipidemia, CAD s/p left circumflex stent 2 years prior presented to the ED with worsening intermittent exertional chest pain relieved by rest. Written by Nathanael Franks MD, reviewed by Meyers, Smith, Grauer, etc. In my opinion, I think it looks more like subendocardial ischemia.
