Insights
Sudden cardiac death in children, often from ventricular tachycardia, requires immediate resuscitation and electrical cardioversion. This case highlights prompt intervention
Area of Science:
- Pediatric Cardiology
- Emergency Medicine
- Clinical Case Study
Background:
- Sudden cardiac death in children is rare but frequently linked to ventricular tachycardia.
- Pulseless ventricular tachycardia necessitates immediate prehospital interventions, including cardiopulmonary resuscitation and external electrical cardioversion.
Observation:
- A case of pulseless ventricular tachycardia in a previously healthy child is presented.
- Successful resuscitation to sinus rhythm was achieved after 12 minutes of cardiorespiratory resuscitation and three external electrical shocks.
Findings:
- An extensive diagnostic workup was performed to identify the underlying cause of the ventricular tachycardia.
- The child experienced severe encephalopathy following the event.
Implications:
- This case underscores the critical importance of timely and effective prehospital management for pediatric pulseless ventricular tachycardia.
- The authors discuss various etiologies and treatment strategies for pediatric arrhythmias, referencing the pediatric algorithm for shockable rhythms.
Abstract:
Cardiac arrhythmia with sudden death is rare in children but mainly due to ventricular tachycardia. In case of pulseless ventricular tachycardia, prehospital treatment is crucial with immediate cardiopulmonary resuscitation and external electrical cardioversion. We report the case of pulseless ventricular tachycardia in a child with no past medical history. Sinus rhythm was obtained after 12min of cardiorespiratory resuscitation and three external electrical shocks. An exhaustive diagnostic approach allow us to find its origin. The clinical progression was marked by a severe encephalopathy. The authors discuss different etiologies and treatment of arrhythmia in children, reviewing the pediatric algorithm for shockable rhythm.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
