Does hierarchical physiologic pacing (closer position to His bundle and LV endocardium) improve LVEF response in conduction system pacing?
Positioning the pacing lead closer to the His bundle and LV endocardium may enhance LVEF response in conduction system pacing.
Hierarchical physiologic pacing with improved LVEF response is achieved with a closer position of the pacing lead to the His bundle and the LV endocardium.
Ponnusamy et al. (Sat,) studied this question.
