Right bundle branch pacing: Criteria, characteristics, and outcomes

Heart RhythmPublished Observational study

Authors' conclusion

RBBP has distinct features that separate it from HBP and is observed in approximately a fifth of patients in whom HBP is intended.

Study context

Population
Patients with confirmed right conduction system pacing targeted for His bundle pacing (HBP)
Participants
326 patients
Exposure
Right bundle branch pacing (RBBP) vs HBP
  • RBBPn = 64
Outcome
RBBP prevalence among patients targeted for HBP
