A patient had a cardiac arrest with ventricular fibrillation and was successfully defibrillated. The proof of this is that only 5% of patients enrolled had acute coronary occlusion. Lemkes JS, Janssens GN, van der Hoeven NW, et al. Coronary Angiography after Cardiac Arrest without ST-Segment Elevation. 5% vs. 58%!!

2 Standard management for VT and VF involves the use of electrical defibrillation, high-quality chest compressions, and epinephrine. Initial guidelines defined “refractory” as VT or VF occurring despite three shocks from a cardiac defibrillator. Tips for use of dual sequence defibrillation 11 : Use the same model of defibrillator.

Date: September 8th, 2021 Reference: Desch et al. Date: September 8th, 2021 Reference: Desch et al. 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.

It shows a proximal LAD occlusion, in conjunction with a subtotally occluded LMCA ( Left Main Coronary Artery ). Upon contrast injection of the LMCA, the patient deteriorated, as the LMCA was severely diseased and flow to all coronary arteries ( LAD, LCx and RCA ) was compromised. He was taken immediately to the cath lab.

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). Most OMI have a peak Troponin T over 1000 ng/L [reference: Baro R et al. Clinical Cardiology 2019.

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. Paradoxically, though, the third green arrow identifies a QRS that is more narrow than the RBBB complexes surrounding it. References Chiale, P.
