Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." 2014 AHA/ACC guideline for the management of patients with non–ST-elevation acute coronary syndromes. The case continues. Kontos, M.

Step 1 to missing posterior MI is relying on the STEMI criteria. A prospective validation of STEMI criteria based on the first ED ECG found it was only 21% sensitive for Occlusion MI, and disproportionately missed inferoposterior OMI.[1] But it is still STEMI negative. A 15 lead ECG was done (below). In a study last year, 14.4%

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?

LVH and the diagnosis of STEMI - how should we apply the current guidelines? Journal of Electrocardiology 47 (2014) 655–660. This one mimics inferior STEMI (Figure 4): Concentric LVH, NO wall motion abnormality Case 5. How about diagnosing anterior STEMI in the setting of LVH? For details, read this post.

Key metrics and clinical outcomes were compared before and after CSP implementation. Methods This study included consecutive patients with iSTEMI treated with percutaneous coronary intervention (PCI) between 1 January 2011 and 15 July 2019 at a single, tertiary referral centre.

This is technically a STEMI, with 1.5 However, I think many practitioners might not see this as a clear STEMI, and would instead call this "borderline." They collected several repeat ECGs at the outside hospital before transport: None of these three ECGs meet STEMI criteria. This ECG was recorded on arrival: What do you think?

Here is the Queen of Heart's interpretation: The cath lab had been activated for concern of STEMI. Other outcome information is not available. Learning Points: This is one of many examples of false positive STEMI criteria, which is distinguishable by expert humans, and now by AI such as QOH. No prior ECG was available.
