Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing
Key Points
The primary aim is to compare the effects of left bundle branch area pacing (LBBAP) and biventricular pacing (BiVP) on the electromechanical window (EMW) in CRT patients.
Participants had a negative electromechanical window at baseline.
Both LBBAP and BiVP interventions were applied.
Comparative analysis of changes in EMW was conducted post-intervention.
Both LBBAP and BiVP reverted the electromechanical window negativity.
The extent of reversion was found to be similar for both pacing methods.
Abstract
In CRT patients with a negative EMW at baseline, LBBAP and BiVP revert EMW to a similar degree.
