Why the study?
Does apical pacing compared to medial septum or free wall pacing reduce pacemaker-induced dyssynchrony in outpatients with >80% right ventricular stimulation and preserved LVEF?

RV pacing site selection remains uncertain without baseline dysfunction; leaves open which location best minimizes dyssynchrony.
Does apical pacing compared to medial septum or free wall pacing reduce pacemaker-induced dyssynchrony in outpatients with >80% right ventricular stimulation and preserved LVEF?
Apical right ventricular pacing is associated with lower interventricular conduction delay compared to mid-septal pacing, suggesting it remains a viable option for lead placement.
Osório et al. (2017) studied this question.
