Normalization of Diagnostic For STEMI Prehospital ECG with Nitroglycerin Therapy. If the initial ECG was diagnostic for STEMI the paramedic called to mobilize the reperfusion team.

Acute anterior STEMI tends to be a more difficult ECG diagnosis than acute inferior STEMI. That’s because with acute inferior STEMI there’s almost always a downsloping ST-segment in lead aVL to help shore up the diagnosis. Once again, this acute anterior STEMI “crosses over” to the high lateral leads.

They did not find one STEMI on their triage ECGs (no surprise! We at HCMC have 30 walk-in STEMIs per year; the rest come by ambulance. October 2018. Fair enough.

There is a very small amount of STE in some of the anterior, lateral, and inferior leads which do NOT meet STEMI criteria. The case was reviewed by all parties, and it was stated correctly that the ECG does not meet the STEMI criteria. In the ambulance during transport, the patient suddenly suffered VF arrest.

We have a large number of graduate paramedics starting with Ambulance Victoria this year, so it’s probably a good time to revisit a topic that seems to receive surprisingly little attention in an industry that relies so heavily upon it. This means that wherever possible the closest ambulance is sent to high priority cases.

There is an obvious inferior STEMI, but what else? Besides the obvious inferior STEMI, there is across the precordial leads also, especially in V1. This STE is diagnostic of Right Ventricular STEMI (RV MI). In fact, the STE is widespread, mimicking an anterior STEMI. EKG is pictured below: What do you think?

If it was a shockable rhythm, and the ECG is showing clear-cut STEMI, we want to activate the cardiac cath lab. In my system, we announce CODE-STEMI over the radio and get a time stamp, and we follow up with ECG transmission. Our receiving hospital is a PCI hospital so we don’t need to consider bypassing the local non-PCI hospital.

It was a constant ache on the left side of his chest that forced him to stop cycling and call for an ambulance. The chest pain started about one hour prior to arrival while bike riding. It was radiating to his bilateral upper arms. It was associated with nausea but he denied dyspnea, dizziness, and headache.

The nitro she took in the ambulance did not help. Patients like her are the reason we are advocating for a change in the ACS paradigm from STEMI to OMI. While she was in her bed at home, she had sudden onset of left sided chest pain that radiated to her shoulder. The pain was pleuritic, without nausea or diaphoresis.

He reportedly told his family "I think I'm having a heart attack", then they immediately drove him to the ED, and he was able to ambulate into the triage area before he collapsed and became unresponsive. CPR was initiated immediately. It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation.
