Abstract

Objective: The study aimed to assess the short-term effects of apical RV pacing on LV function and twist mechanics using speckle tracking echocardiography.

Background: The myofibers of the heart has geometric orientation that induces its characteristic wringing motion around its long axis during contraction leading to the systolic LV twist. This motion is created by the apical and basal rotations that are oppositely directed and has an important role in regulation of LV function. Several studies have demonstrated that LV systolic function and mechanics had delayed deterioration after RV apical pacing with limited data regarding the acute effects.
