Overview

May inform ICD follow-up in idiopathic VF survivors; leaves open optimal programming strategies pending larger cohorts.

Key Points

  • To highlight the occurrence of idiopathic ventricular fibrillation leading to cardiac arrest despite normal evaluations.
  • Case report of a 50-year-old man
  • Preoperative cardiovascular evaluation followed by cardiac arrest
  • Interventions included CPR, defibrillation, and implanted cardioverter-defibrillator.
  • Patient experienced cardiac arrest after cardiovascular clearance with no prior symptoms.
  • Implantable cardioverter-defibrillator confirmed sustained ventricular tachycardia post-resuscitation.
  • Highlights potential undetected arrhythmias despite negative structural evaluations.

Case Report (n=1)

Structured PICO

P
Population
A 50-year-old man who suffered out-of-hospital cardiac arrest approximately 1 hour after preoperative cardiovascular clearance.
I
Intervention
Dual-chamber implantable cardioverter-defibrillator (ICD) implantation for secondary prevention.
O
Outcome
Recurrent malignant arrhythmias (sustained ventricular tachycardia).hard clinical

Idiopathic ventricular fibrillation can present as sudden cardiac arrest despite reassuring preoperative cardiovascular evaluation, and survivors remain at high risk for recurrent arrhythmias requiring ICD therapy.

Cite This Study

Ganthan et al. (2026) conducted a case report in Idiopathic ventricular fibrillation (n=1). Implantable cardioverter-defibrillator was evaluated on Recurrent malignant arrhythmias. A 50-year-old man with idiopathic ventricular fibrillation experienced recurrent sustained ventricular tachycardia that was successfully terminated by an implantable cardioverter-defibrillator.
