About this trial
This clinical investigation is a prospective, single-arm, post-market, non-randomized, single-center study designed to evaluate the effectiveness of the SyncAV CRT dynamic atrioventricular (AV) delay feature when used with left bundle branch area pacing (LBBAP).
Eligibility criteria
Qualifiers
Patient is 18 years of age and willing to comply with the study requirements
Patients with approved indication for dual-chamber pacing or cardiac resynchronization therapy and scheduled to be implanted with an Abbott pacing system
Patient has documented left bundle branch block (LBBB) or intraventricular conduction delay (IVCD)
Patient has an intrinsic QRS duration ≥ 130 ms
Disqualifiers
Patient has a resting ventricular rate > 100 bpm
Patient has AV Block (2nd or 3rd degree)
Patient has documented persistent atrial tachycardia or atrial fibrillation
Patient has had a recent myocardial infarction, ablation, electrolyte imbalance, or any condition within the last 90 days that would contraindicate for pacing device programming changes in the opinion of the investigator
