The ST segment changes are compatible with severe subendocardial ischemia which can be caused by type I MI from ACS or potentially from type II MI (non-obstructive coronary artery disease with supply/demand mismatch). The arrhythmia spontaneously converted before defibrillation was achieved. This is an ominous sign.

More past history: hypertension, tobacco use, coronary artery disease with two vessel PCI to the right coronary artery and circumflex artery several years prior. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc. It is unknown when this pain recurred and became constant.

He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardial infarction, or any prior PCI/stent. Despite immediate chest compressions, and multiple rounds of defibrillation, he could not be resuscitated. Breath sounds were clear in all lung fields.

Below is the version standardized by PM Cardio app Meyers interpretation: Findings are specific for posterior (and also likely inferior) wall transmural acute infarction, most likely due to acute coronary occlusion (OMI). There is a relatively normal QRS yet there is STD maximal in V2-V4, which resolves from V4 to V6.

On arrival to the ED, this ECG was recorded: What do you think? Although predicting the "culprit" artery of acute coronary occlusion is often straightforward ( ie, based on the distribution of leads with ST elevation and leads with reciprocal ST depression ) — this is not always the case. This prompted cath lab activation.

Finally, head-up CPR (which was not used here), makes for better resuscitation.

Submitted by Dr. George Mastoras (Twitter @georgemastoras), written by Jesse McLaren It’s a busy day in the ED when you’re sent another ECG to sign off from a patient at triage. Here is the post shock ECG: Cardiology was called stat for ischemic VT, query SCAD vs thrombotic occlusion vs coronary vasospasm.

We can, therefore, put down the defibrillation pads, set aside the amiodarone, and look further at the ECG. The coronary angiogram revealed no critical stenosis, or acute plaque ulceration.

She was defibrillated and resuscitated. Hospital Course The patient was taken emergently to the cath lab which did not reveal any significant coronary artery disease, but she was noted to have reduced EF consistent with Takotsubo cardiomyopathy. One need not have obstructive coronary disease to have occlusive thrombus!

If the patient only had these two ECGs recorded, it would have missed the transient time between them which were STEMI positive, and the patient would then have arrived at the ED as “serial ECGs STEMI negative."

She was never defibrillated. I was texted this ECG in real time, but it turns out to actually be the 2nd one recorded in the ED. ECG #4 — This is the 3rd ECG that was done in this case ( obtained ~1 hour after arrival in the ED ). As was seen in this case — defibrillation and/or overdrive pacing may be needed.

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. It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. CPR was initiated immediately.
