Implication

Warrants caution for proarrhythmic ICD pacing; case report leaves open its incidence and implications for device programming.

Key Points

Document and characterize a novel form of proarrhythmia where internal cardioverter defibrillator (ICD) pacing triggers ventricular fibrillation.
Analyzed telemetry data and device logs from two ICD recipients (N=2) presenting with device-associated arrhythmias.
Pacemaker stimulation directly triggered ventricular fibrillation in two reported cases.
The implanted devices successfully detected the pacing-induced arrhythmias and delivered corrective defibrillation therapy to terminate ventricular fibrillation.

Structured PICO

Can ICD pacing induce ventricular fibrillation in patients with internal cardioverter defibrillators?

Population

2 patients with internal cardioverter defibrillators (ICDs)

Intervention

ICD pacing function

Outcome

Pacing induced ventricular fibrillation (VF)safety

ICD pacing can act as a proarrhythmic trigger, inducing ventricular fibrillation that the device must then terminate.
