Two recent interventions have proven in randomized trials to improve neurologic survival in cardiac arrest: 1) the combination of the ResQPod and the ResQPump (suction device for compression-decompression CPR -- Lancet 2011 ) and 2) Dual Sequential defibrillation. Finally, head-up CPR (which was not used here), makes for better resuscitation.

Furthermore, among 35 patients with acute left main coronary artery occlusion, 9 presented with RBBB (mostly with LAH) on the admission ECG. Here are three more dramatic cases that illustrate RBBB + LAFB Case 1 of cardiac arrest with unrecognized STEMI, died.

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.

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. Any indications for cath lab activation?

He underwent CPR, and regained a pulse after epinephrine, with an organized narrow complex rhythm at 140, but still with severe shock. And so it is wise to look at the coronary arteries. This ECG certainly looks like myocarditis, and was due to myocarditis, but missing acute coronary occlusion is not acceptable.

Data that do not establish neurological risk stratification in the first 6 hours after CA include the patient’s age, duration of CPR, seizure activity, serum lactate level or pH, Glasgow motor subscore in patients who received NMB or sedation, pupillary function in patients who received atropine, and optic nerve sheath diameter (95.3%, 20/21).

He underwent immediate CPR, was found to be in ventricular fibrillation, and was successfully resuscitated. He underwent coronary stenting (uncertain which artery). See explanation below. The patient went home and, in front of his wife, he collapsed. I do not have the post-resuscitation ECG.

It does take some time for thrombus to form, but the EKG and the troponin profile show that this was NOT a late presentation STEMI.

Post by Smith and Meyers Sam Ghali ( [link] ) just asked me (Smith): "Steve, do left main coronary artery *occlusions* (actual ones with transmural ischemia) have ST Depression or ST Elevation in aVR?" All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery? Widimsky P et al.

He underwent CPR and then was shocked out of VF. Both hyperacute T waves and posterior OMI are now formally endorsed as "STEMI equivalents" by the ACC. == MY Comment, by K EN G RAUER, MD ( 11/23 /2022 ): == Cases in which initial ECG findings are subtle before undergoing dramatic change, — are always impressive.

The assay at my institution, for example, is frequently negative until 4-6 hours after acute coronary occlusion. This rhythm reportedly produced no palpable pulse, and CPR was continued. 30 seconds later, however, the patient began spontaneously moving and CPR was discontinued.

CPR was initiated immediately. As in all ischemia interpretations with OMI findings, the findings can be due to type 1 AMI (example: acute coronary plaque rupture and thrombosis) or type 2 AMI (with or without fixed CAD, with severe regional supply/demand mismatch essentially equaling zero blood flow).
