Author: Brit Long, MD (@long_brit) // Reviewed by Alex Koyfman, MD (@EMHighAK) The American Heart Association 2023 Guideline Updates for 2023 were just published. With respect to timing, for cardiac arrest with a shockable rhythm, it may be reasonable to administer epinephrine after initial defibrillation attempts have failed.

He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR. Cardiac arrest #3: ST depression, Is it STEMI? This patient was witnessed by bystanders to collapse. They started CPR.

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. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc. Sensitivity was 87% for OMI in our validation study (it was 34% for STEMI criteria).

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.

There’s inferior ST depression which is reciprocal to subtle lateral convex ST elevation, and the precordial T waves are subtly hyperacute – all concerning for STEMI(-)OMI of proximal LAD. There’s ST elevation I/aVL/V2 that meet STEMI criteria. This is obvious STEMI(+)OMI of proximal LAD. Non-STEMI or STEMI(-)OMI?

When the ICD was finally interrogated, the syncopal events and shocks correlated with two VF events that were defibrillated successfully. Recall that air is a poor conductor of electricity and will, therefore, generate smaller amplitudes on posterior leads (hence why STEMI criteria requires only >0.5
