Why the study?
The study was conducted to explore whether electromechanical activation time (EMAT) can confirm that left bundle branch pacing produces more satisfactory left ventricular electromechanical synchronization than conventional right ventricular pacing modalities.
Does left bundle branch pacing improve left ventricular electromechanical synchronization compared to conventional right ventricular pacing in patients with standard pacing indications?
Population
55 patients with standard pacing indications and narrow QRS duration

EMAT may validate superior LV synchrony with LBBP; leaves open clinical adoption pending randomized outcome trials.
Does left bundle branch pacing improve left ventricular electromechanical synchronization compared to conventional right ventricular pacing in patients with standard pacing indications?
Acoustic cardiography demonstrates that left bundle branch pacing preserves left ventricular electromechanical synchronization better than conventional right ventricular pacing, closely mimicking intrinsic rhythm.
