Analysis of the Pattern of Initiation of Sustained Ventricular Arrhythmias in Patients with Implantable Defibrillators
Key result
Late-coupled ventricular premature depolarizations initiated 85% of sustained ventricular arrhythmia episodes, regardless of the type or severity of underlying structural heart disease.

Implication
Late-coupled VPDs may guide VA monitoring in ICD patients; extends prior observations but leaves open targeted interventions across SHD.

Outcome
Pattern of initiation of sustained ventricular arrhythmias (coupling interval, prematurity index, initiating sequence)
Sustained ventricular arrhythmias in patients with ICDs are typically initiated by late-coupled ventricular premature depolarizations, regardless of underlying structural heart disease.

Taylor et al. (2000) conducted an observational in Sustained ventricular arrhythmias in patients with implantable defibrillators (n=90). Late-coupled ventricular premature depolarizations initiated 85% of sustained ventricular arrhythmia episodes, regardless of the type or severity of underlying structural heart disease.
