A 40-something with persistent Ventricular Fibrillation presented after attempted prehospital resuscitation A 40-something with no previous cardiac history presented to the ED in persistent Ventricular Fibrillation after attempted prehospital resuscitation. Finally, head-up CPR (which was not used here), makes for better resuscitation.

He reports that this chest pain feels different than prior chest pain when he had his STEMI/OMI, but is unable to further describe chest pain. Sensitivity was 87% for OMI in our validation study (it was 34% for STEMI criteria). He reports feeling nauseated with emesis. The Queen was not used in real time. Even the Queen can be wrong.

Jesse McLaren (@ECGcases), of Emergency Medicine Cases Reviewed by Pendell Meyers and Steve Smith An 85yo with a history of hypertension developed chest pain and collapsed, and had bystander CPR. The patient was brought to the ED as a possible Code STEMI and was seen directly by cardiology. Which was the culprit lesion?

It may be difficult to read STEMI in the setting of RBBB. There is, however, a long QT also, with abnormal T-waves, but this is not STEMI. This ECG was recorded prehospital, and the computer read STEMI, so the medics activated the cath lab: What do you think? The ECG is consistent with high lateral STEMI. Called 911.

This is a 30-something healthy patient presented with COVID pneumonia who presented to the ED. He underwent CPR, and regained a pulse after epinephrine, with an organized narrow complex rhythm at 140, but still with severe shock. 12 All STEMI patients had very high cTn typical of STEMI (cTnT > 1.0

About an hour later, he was then found on the floor in cardiac arrest in the ED. He underwent CPR and then was shocked out of VF. The history in today's case — was that of a man in his 70s who presented to the ED for 2 hours of chest pain , that was still present on arrival in the ED. But we should not be surprised.

Here is his ECG on presentation to the ED, approximately 45 minutes after onset of pain, but with pain improving since onset: What is your interpretation? The initial ECG was interpreted as "normal" by the computer ( Algorithm: Marquette GE / 12SL ) and "no acute ischemic changes" by the ED physician.

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.

Smith and Meyers answer: First , LM occlusion is uncommon in the ED because most of these die before they can get a 12-lead recorded. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery? The pattern seen may, or may not, be unique to left main occlusion.

I would rather use a PCAC score to decide on transfer than arrest characteristic (time of CPR, initial rhythm, etc) because we know that all of that data is prone to bias as well. We hope that PCAC would be similar, but I’m not sure we have enough data to be sure. Right now, we do not use PCAC in our decisions to transfer or not, by the way.
