Why the study?
Does left bundle branch pacing improve safety and pacing parameters compared to right ventricular pacing in bradycardia patients?
Does left bundle branch pacing improve safety and pacing parameters compared to right ventricular pacing in bradycardia patients?
Left bundle branch pacing is feasible and safe in bradycardia patients over 18 months, providing narrower QRS duration than right ventricular pacing without increasing long-term complications.
LBBP was associated with narrower QRS and similar short-term safety versus RVP; leaves open long-term superiority, requiring randomized confirmation.
Left bundle branch pacing was feasible in bradycardia patients associated with stable pacing parameters during 18 months follow-up. Paced QRS duration was significantly narrower than that of RVP. Though cTnT elevation was more significant in LBBP within 2 days post-procedure, the complications, and cardiac outcomes were not significantly different between two groups.
