He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. Then assume there is ACS. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR. This patient was witnessed by bystanders to collapse. They started CPR. sodium bicarbonate.

He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED. There was no bystander CPR. Here is the initial ED ECG.

With respect to timing, for cardiac arrest with a shockable rhythm, it may be reasonable to administer epinephrine after initial defibrillation attempts have failed. Consider administering epinephrine after defibrillation in those with shockable rhythms. COR 2b, LOE B-R. COR 2b, LOE B-R. COR 3, No benefit, LOE B-R. COR 2a, LOE B-R.

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. She arrives in the emergency department (ED) with decreased level of consciousness and shock.

This is diagnostic of ACS; it appears to be a reperfused acute inferior OMI. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc. Then the patient would have been taken to the critical care area with a defibrillator at his side while waiting for the cath lab to be ready.

During angiogram in the cath lab, the patient suffered two episodes of ventricular fibrillation for which he was successfully defibrillated. ST depression maximal in V1-V4, without a QRS abnormality clearly causing it, in the setting of ACS symptoms, is very concerning for posterior MI until proven otherwise. What do you think?

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. ACS would be highly unusual in a young athlete, and given the information on his race bib, one must first suspect that the abnormal ST elevation is due to demand ischemia, not ACS. On his bib it stated that he had a congenital heart disorder.
