Nonexcitatory stimulus delivery improves left ventricular function in hearts with left bundle branch block.

Abstract

INTRODUCTION Preliminary data in a heart failure animal model and isolated muscle preparation have suggested that nonexcitatory stimulation (NES) improves left ventricular (LV) function. METHODS AND RESULTS We compared biventricular (BV) pacing with NES in an animal model with left bundle branch block (LBBB). The left bundle branch (LBB) was ablated in… (More)
