Implication
Asynchronous pacing may interfere with ICD detection in dual-device patients; leaves open whether shorter refractory periods mitigate risk.
Structured PICO
What are the mechanisms underlying asynchronous pacemaker activity during ventricular arrhythmias in patients with both pacemakers and ICDs?
P
Population
19 patients with both pacemakers and implantable cardioverter defibrillators (ICDs) undergoing procedures with induced ventricular arrhythmias (39 induced arrhythmias from 26 different procedures)
I
Intervention
Pacemaker telemetry analysis during induced ventricular arrhythmias
O
Outcome
Mechanisms underlying asynchronous pacemaker activity (nonsensing vs. noise reversion) and interference with ICD detectionsafety
Noise reversion is a frequent cause of asynchronous pacemaker activity during ventricular arrhythmias that can interfere with ICD detection, highlighting the importance of programming short ventricular refractory periods.
