Abstract
Objective:To explore the impacts of right ventricular alternative site pacing on left ventricle contractibility and sys-tolic synchronicity by real-time three dimensional echocardiography .Methods :Tweenty patients with atrio-ventricular (AV ) blocks undergoing dual-chamber pacemaker implantation were divided into the right ventricular apex pacing group (Group RVA) and the right ventricular outflow tract pacing group (Group RVOT ) according to the different pacing sites . Left ventricular volume ,ejection fraction and LV regional wall motion were assessed by echocardiography before and 3 months after operation .The left ventricle contractibility and systolic synchronicity were compared between the two groups .Results:Stand-ard deviation and difference of time to minimum systolic volume (Tmsv-dif ,Tmsv-dif% ,Tmsv-sd ,Tmsv-sd% ) of 16 seg-ments ,12 segments and 6 segments ,LV volume ,excursion and regular 2D parameters do not differ .Conclusions :RVA and RVOT pacing are the same in terms of LV synchrony in short time follow-up .关键词
