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. But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR. They started CPR.

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.

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.

Resus 2023. Indication for emergency invasive coronary angiography or had coronary angiography within 1 hour of arrival. Known obstructive coronary artery disease or known coronary stent. Known cardiac defibrillator. Resus 2023. Advanced imaging post-arrest is a possible modality to achieve this end.

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 underwent coronary angiography which showed severe multivessel disease, and he agreed to proceed with workup for CABG. But artifact is "alive and well" — and learning to recognize it will amaze many of your colleagues ( and may serve to avoid an unnecessary defibrillation or two ). The March 17, 2023 post — for PTA.
