Left bundle area pacing: Guiding implant depth by ring measurements
Authors' conclusion
Ring pacing parameters are more predictive of lead progress than tip measurements. Lead depth and lead-septal angle can be determined from ring impedance measurements.
Study context
- Population
- Patients with standard pacing indications undergoing left bundle area pacing (LBAP) with SelectSecure 3830 leads via C315 sheaths
- Participants
- 73 patients
- Exposure
- Successful vs unsuccessful LBAP lead implant attempts
- Outcome
- Dynamics in pacing parameters (ring and tip measurements)
Main finding
As reported in the abstract
- Ring impedance increased stepwise during successful vs unsuccessful attempts
- P = .039
- Wider lead-septal angle correlated with higher ring impedance
- P = .036
- Unipolar ring threshold correlated with lead implant depth
- P = .029
Observational data: associations, not effects.
