Improvement of abnormal systolic motion of the interventricular septum with cardiac resynchronization therapy

ConclusionCircumferential contraction of septal myocardial fibers is improved with CRT and it is strongly correlated with increase of aortic VTI and shortening of QRS duration. These findings predict the deterioration of septal contraction as the main mechanism in patients with LBBB pattern and, CRT may improves myocardial contraction by correcting septal systolic motion.This article is protected by copyright.
