Learners perform initial assessment, lead placement, monitoring, IV/oxygen setup, and atropine for symptomatic bradycardia while preparing transcutaneous pacing. The case then requires immediate pacing cessation, defibrillation, high-quality CPR, epinephrine and amiodarone delivery, and identification of reversible causes during PEA.
