Mapping and Pacing of the His Bundle for Heart Failure Patients With Left Bundle Branch Block
United States18 participantsStarted 2019-03-20
Plain-language summary
This is a prospective, single-arm, non-randomized, non-blinded study designed to characterize the locations of His Bundle (HB) pacing that results in correction of electrical dyssynchrony and to characterize morphology and activation time of local intracardiac electrogram (IEGM) with an electro-anatomical mapping system during a device implant procedure and secondarily to assess the efficacy of HB pacing or HB plus LV pacing (when indicated) in correction of electrical dyssynchrony in heart failure patients with left bundle branch block.

✕. Pregnant or nursing subjects and those who plan pregnancy during the clinical investigation follow-up period.
✕. Recent (\< 3 months) myocardial infarction, ablation, electrolyte imbalance, or any condition within the last 90 days that would contraindicate for pacemaker or CRT implant in the opinion of the investigator
✕. Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
