Abstract
Objective To compare the effects of different parts of ventricular pacing on left ventricular function. Methods 130 pa-tients with implantation of permanent pacemaker were divided into 4 groups according to the different pacing sites ,group A (apex of right ventricle ,n=35 ) ,group B (high right ventricular septal surface ,n=25 ) ,group C (middle right ventricular septal surface ,n=28) ,group D (low right ventricular septal surface ,n=32).Left ventricular ejection fraction (LVEF) ,left ventricular end dias-tolic volume (LVEDV) ,serum N terminal B type natriuretic peptide precursor (serum NT_proBNP) ,QRS wave duration ,incidence of cardiovascular event of patients in the four groups before and 1.5 years after operation were compared. Results Compared to pa-tients before operation ,patients in group A had lower LVEF 1.5 years after operation ( P<0.05).Compared to patients before oper-ation ,patients in group A and group D had higher LVEDV 1.5years after operation.Group A had the highest LVEDV of patients a-mong the four groups (P<0.05).Compared to patients before operation ,patients in group A ,B and D had higher NT_proBNP.Group A had the highest NT_proBNP of patients among the four groups ( P<0.05).Group A had the widest QRS wave duration of the four groups while group C had the narrowest ( P<0.05).The incidence of cardiovascular event of patients in group C (3.6% ) was lower than that in group A (40.0% ) and group D (21.9% ,P<0.05).Conclusions The right ventricular septal surface in median had low influence in left ventricular function and low incidence of vascular events and can be the best part of implantation of perma-nent pacemaker.关键词
