STEMI Interpretation

I’ve been spending a great deal of time at my clinical coordinator job looking at STEMI cases, as well as putting together educational material. When we take a class in STEMI recognition, the ECGs, once you know how to read them, are all pretty clear cut. You can flash the 12-leads on the screen and […]


Something really nice happened today. I was in the supply closet, putting away our latest shipment, when my partner came in and said someone was here to see me. I walked out through the bay and into the main area and there was a man and a woman in maybe their late forties. The woman […]

Then there are the legitimate calls like strokes and traumas, but too often in those calls there is really not much we can do to fix them. They are dead from getting […]
