Chronic wireless communication between dual-chamber leadless pacemaker devices
Authors' conclusion
Wireless implant-to-implant communication in the new dual-chamber leadless pacemaker system demonstrated successful transmissions in >90% of beats throughout the 6-month evaluation period. Communication success improved significantly over time postimplant for specific subgroups.
Study context
- Population
- Patients meeting standard dual-chamber pacing indications, de novo dual-chamber leadless pacemaker (LP) implant
- Participants

- Outcome
- Chronic i2i transmission success rates (A-to-V and V-to-A)
- Follow-up
- Implant, discharge, 1, 3 and 6 months postimplant

Main finding
As reported in the abstract
i2i success rate · implant to 6M
Median ALP-to-VLP (A-to-V) and VLP-to-ALP (V-to-A) i2i success rates exceeded 90% of beats at all time-points
>90%
Observational data: associations, not effects.

- 19%
- V-to-A <70% at implant
- 31%
- Improvement by 1M
- roughly 40%
