Bradyarrhythmia in toy breeds presents unique lead routing and pocket-size constraints. This follow-up series tracks 24 implantations from 2022–2025.
Cohort
Median weight 5.4 kg; AV block and sick sinus syndrome were the dominant indications.
Follow-Up
Three-year survival was 82%; owner-reported activity scores improved in 88% of survivors.
Lessons Learned
- Prefer jugular approach in dogs under 4 kg
- Schedule generator revision planning at implant
- Telemetric checks reduce emergency presentations
