Quantitative analysis reveals influencing factors to facilitate successful anodal-ring capture in left bundle branch pacing
Authors' conclusion
This study elucidated the factors affecting the success likelihood of LBBP-ARC.
Study context
- Population
- Patients receiving left bundle branch pacing (LBBP) with intraoperative anodal-ring capture (ARC) testing
- Participants
- 105 patients
- Exposure
- LBBP with ARC vs LBBP without ARC
- LBBP-ARCn = 65
- Outcome
- Factors influencing ARC implementation
Main finding
As reported in the abstract
ARC success
| Group | Value | Average ARC output |
|---|---|---|
| LBBP-ARC | 62% | 3.1 V/0.5 ms |
LBBP-ARC
Value62%
Average ARC output3.1 V/0.5 ms
Observational data: associations, not effects.
Further findings
Further shortening of stimulus-to-QRS duration (stim-QRSd) with ARC
- ARC further shortened stim-QRSd
- 13.1 ± 7.5 ms
Unipolar-ring (cathodal) threshold and R-wave sensing
- Better unipolar-ring (cathodal) threshold and R-wave sensing in LBBP-ARC group, indicating critical role of ring-septum contact
Lead-tip site distribution
- Longer corrected longit-dist and shorter corrected lat-dist positively correlated with higher ARC success likelihood
