This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI.

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). Smith Comment: Is is common for the artery to be open at angiogram in OMI, including full STEMI.

Defibrillation is the treatment of choice in these cases but does not often result in sustained ROSC ( Kudenchuk et al 2006). Acute coronary syndrome (ACS) is responsible for the majority (60%) of all OHCAs in patients. Many of these OHCAs are due to ventricular fibrillation or pulseless VT.

More past history: hypertension, tobacco use, coronary artery disease with two vessel PCI to the right coronary artery and circumflex artery several years prior. 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. So it can miss some OMI.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. It shows a proximal LAD occlusion, in conjunction with a subtotally occluded LMCA ( Left Main Coronary Artery ). He required multiple defibrillations within a period of a few hours. The below ECG was recorded. He was taken immediately to the cath lab.

He underwent further standard resuscitation EXCEPT that we applied the Inspiratory Threshold Device ( ResQPod ) AND applied Dual Sequential Defibrillation (this simply means we applied 2 sets of pads, had 2 defib machines, and defibrillated with both with only a fraction of one second separating each defibrillation.

She underwent coronary angiography which showed thrombotic occlusion of an RPL branch s/p aspiration thrombectomy. Queen : she saw no OMI (no "STEMI Equivalent") either Continued : Now, she says she was walking to the bathroom when she experienced acute onset substernal chest pressure radiating into her neck and left arm.

Here is the post shock ECG: Cardiology was called stat for ischemic VT, query SCAD vs thrombotic occlusion vs coronary vasospasm. Cath lab was activated: There was no coronary artery disease, but there was spontaneous coronary artery dissection (SCAD) of the distal LAD, which was narrowed by 95%, and treated medically.

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!

There are a few subtle signs of coronary occlusion here. He was defibrillated. Anterolateral STEMI. He had an ECG recorded: Sinus Rhythm. This was read as normal by the emergency physician and by the computer. QTc is 400 ms. What do you think? First , look at V4-V6. The T-wave is almost as tall as the R-wave. This should not be.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. The next day, and angiogram showed normal coronary arteries. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. His initial ECG is shown here.

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