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.

Calcium is associated with harm but is still necessary in certain situations (hyperkalemia, calcium channel blocker overdose) (Level 3 recommendation: no benefit). With respect to timing, for cardiac arrest with a shockable rhythm, it may be reasonable to administer epinephrine after initial defibrillation attempts have failed.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. He required multiple defibrillations within a period of a few hours. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The below ECG was recorded. What do you think?

This is pathognomonic of hyperkalemia (I suppose it could be due to a massive overdose of a sodium channel blocking drug, maybe). to greatly decrease risk (although in STEMI, the optimal level is about 4.0-4.5 She was in shock with thready pulses. A prehospital ECG was recorded: Limb leads: Precordial Leads What is the therapy?
