Key result
Atrial and ventricular steroid-eluting leads demonstrated low stimulation thresholds (mean range 0.53-0.89 V), allowing >90% of patients to be paced chronically at 2.5 V.
Why the study?
Does atrial pacing with steroid-eluting leads provide comparable stimulation thresholds and performance to ventricular pacing?
Observational (n=123)
Does atrial pacing with steroid-eluting leads provide comparable stimulation thresholds and performance to ventricular pacing?
p-value: p=<0.05
Atrial and ventricular steroid-eluting leads provide excellent stimulation thresholds, allowing for low energy dual chamber pacing.
No takes yet. Share an insight, caveat, or question.
Supports comparable low-threshold atrial and ventricular steroid-eluting leads; leaves open generalizability and practice change pending randomized data.
Hua et al. (1997) conducted an observational in Dual chamber pacing (n=123). Atrial and ventricular bipolar tined steroid-eluting leads (CapSure SP and Encor Dec) vs. Comparison between lead designs and locations (atrial vs ventricular) was evaluated on Stimulation thresholds, electrograms, and pacing impedance (p=<0.05). Atrial and ventricular steroid-eluting leads demonstrated low stimulation thresholds (mean range 0.53-0.89 V), allowing >90% of patients to be paced chronically at 2.5 V.
