Current of injury amplitude during left bundle branch area pacing implantation: impact of filter settings, ventricular pacing, and lead type
Authors' conclusion
High-pass filters have a significant impact on electrogram characteristics at LBBAP implantation, with the 0.5 Hz settings having the most favourable profile.
Study context
- Population
- Consecutive patients with successful left bundle branch area pacing (LBBAP) implantation96 males
- Participants
- 156 patients
- Exposure
- High-pass filter settings; lumenless vs stylet-driven leads
- Outcome
- Impact of high-pass filter settings on COI amplitude in unipolar electrogram recordings
- Follow-up
- Final lead position
Methodological detailsconsecutive patients
- Consecutive patients
Main finding
As reported in the abstract
COI amplitude by high-pass filter setting
Saturation-induced signal loss at 0.05 Hz (average)
10 s
Saturation-induced signal loss at 0.5 Hz (average)
2 s
Observational data: associations, not effects.
Further findings
Sensed current of injury (COI) amplitude when pacing interrupted
- Varied (higher or lower) by up to 4 mV
COI amplitude by lead type
- Lead type did not impact COI amplitude
