Key result
Cumulative right ventricular pacing >2% and ejection fraction <40% were independent predictors for ventricular tachycardia/ventricular fibrillation occurrence and heart failure events.
Why the study?
Does cumulative right ventricular pacing > 2% increase the risk of VT/VF occurrence and heart failure events in patients with an implantable cardioverter-defibrillator?
Cohort (n=250)
Does cumulative right ventricular pacing > 2% increase the risk of VT/VF occurrence and heart failure events in patients with an implantable cardioverter-defibrillator?
Cumulative right ventricular pacing > 2% is an independent predictor of VT/VF and heart failure events in ICD patients, suggesting algorithms to minimize RV pacing should be utilized.
No takes yet. Share an insight, caveat, or question.
Supports minimizing RV pacing in ICD patients; leaves open whether algorithms reduce VT/VF or HF events.
Gardiwal et al. (2008) conducted a cohort in Implantable cardioverter-defibrillator (ICD) patients (n=250). Cumulative right ventricular pacing > 2% vs. Cumulative right ventricular pacing ≤ 2% was evaluated on Ventricular tachycardia/ventricular fibrillation (VT/VF) occurrence. Cumulative right ventricular pacing >2% and ejection fraction <40% were independent predictors for ventricular tachycardia/ventricular fibrillation occurrence and heart failure events.
