Study 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.
Primary Outcome
Collect 3D Locations and electrogram characteristics (morphology and activation time) at the sites where His Bundle (HB) pacing is associated with left bundle recruitment and corrects electrical dyssynchrony at HB pacing implant procedure.
Interventions
- PROCEDURE Mapping and Pacing the His Bundle
- PROCEDURE Placing a guidewire in Coronary sinus for measurement of Q-LV during His Bundle pacing or, if needed, for LV pacing
