Unexpected Pediatric Cardiac Arrest in a Toddler

This case highlights the vital role of prehospital defibrillation, rapid IO access, and recognition of seizure-like activity as a potential recurrent arrhythmia in pediatric VF arrest. While definitive diagnosis, including echocardiography and genetic testing, occurs in the hospital, early EMS intervention-particularly rhythm recognition and timely shock delivery-was lifesaving in this rare pediatric case.
