Traditionally, emergency providers looked for signs of ST-segment elevation myocardial infarction (STEMI) to indicate the need for intervention. Emergency physicians have recognized for some time that there are many occlusions of the coronary arteries that do not present with classic STEMI criteria on the ECG.

Now it even meets STEMI criteria, and HATWs continue to inflate. So the cath lab was not activated. Ongoing OMI.

For instance, there was no protocol for stroke or STEMI. At some point along the way we had protocols for spinal motion restriction, alcohol withdrawal, stroke and STEMI, CPAP, and termination of cardiac arrest resuscitation on scene. The book was approved by the two largest hospitals in Hartford. Paramedics didnt do 12-lead ECGs then.

The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

The biggest problem with STEMI criteria are false negatives – because this costs patient’s myocardium, with greater mortality and morbidity. For this reason, ECGs need first to be interpreted in isolation, and then applied to the patient. Could this false positive cath lab activation been prevented?

Posterior (posterolateral) acute myocardial infarction (STEMI) The heart is rotated 30° to the left in the thorax.
