The conventional machine algorithm interpreted this ECG as STEMI. It shows sinus tachycardia with right bundle branch block. Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). When EMS found her, she was dyspneic and diaphoretic. Both were wrong.

The prehospital and ED computer interpretation was inferior STEMI: There’s normal sinus rhythm, first degree AV block and RBBB, normal axis and normal voltages. The paramedic notes called STEMI into question: “EMS disagree with monitor for STEMI callout. Vitals were normal except for oxygen saturation of 94%. Vitals were normal.

Sent by Dan Singer MD, written by Meyers, edits by Smith A man in his late 30s presented with acute chest pain and normal vitals except tachycardia at about 115 bpm. Here is the Queen of Heart's interpretation: The cath lab had been activated for concern of STEMI. Here is his triage ECG: What do you think? Do you have a prior?

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?

The "criteria" for posterior STEMI are 0.5 Is it STEMI or NonSTEMI? The patient had no hypertension, no tachycardia, a normal hemoglobin, no drug use, no hypotension/shock, no murmur of aortic stenosis. This is from the 2014 ACC/AHA guidelines. The troponin I returned at 4.1 mm STE in one lead. There is zero ST Elevation.

He commented: "by every measure, this would be RBBB with inferior and lateral STE appearing to be STEMI," but he also noted that there are several features that appear similar to false positives (like the first case above). There is also much STE in V3-V6, especially V4-V6, that must be considered to be STEMI. Peak troponin was 3.21

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. 2 The astute paramedic recognized this possibility and announced a CODE STEMI. 2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease.
