%X Objective To assess longitudinal segmental myocardial strain and displacement of left ventricle (LV) in patients with dual chamber pacing (DDD) using velocity vector imaging (VVI) and to explore the clinical application value of VVI in assessing left ventricular motion. Methods A total of 23 patients before and after DDD pacemaker implantation were enrolled in this study. The peak systolic strain and displacement of ventricular segments were measured with VVI and compared before and after pacemaker implanta...
