摘　　要：目的探析心脏永久性起搏器的不同起搏部位对植入患者心功能的影响。方法200例植入心脏永久性起搏器患者,按照起搏部位不同分为对照组和试验组,每组100例。对照组植入部位为右心室心尖部,试验组植入部位为右心室间隔。对比两组患者植入前后心功能指标[左心室射血分数(LVEF)、左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、B型脑钠肽(BNP)]和生活质量[健康调查简表(SF-36)评分]。结果植入6个月后,两组患者LVEF高于本组植入前,LVEDD、LVESD小于本组植入前,BNP低于本组植入前,且试验组患者LVEF(53.06±5.47)%显著高于对照组的(48.45±5.11)%,LVEDD(52.48±3.32)mm、LVESD(49.07±3.56)mm明显小于对照组的(54.88±3.84)、(51.54±3.42)mm,BNP(67.43±8.06)pg/ml明显低于对照组的(82.18±8.84)pg/ml(P<0.05)。植入6个月后,两组患者SF-36评分均较本组植入前显著提升,且试验组患者SF-36评分(80.06±5.11)分高于对照组的(72.12±5.67)分(P<0.05)。结论在进行心脏永久性起搏器植入时,与右心室心尖部相对比,右心室间隔起搏可以更为有效的改善患者心功能,提高生活质量。Objective To explore the effects of different pacemaker sites on cardiac function in patients with permanent cardiac pacemaker implantation.Methods 200 patients with permanent cardiac pacemaker implantation were divided into a control group and an experimental group according to different pacemaker sites,each with 100 cases.The control group was implanted in right ventricular apex,while the experimental group was implanted in right ventricular septum.Both groups were compared in terms of cardiac function indexes[left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and B-type natriuretic peptide(BNP)]and quality of life[36-Item Short-Form Health Survey(SF-36)score]before and after the implantation.Results After 6 months of implantation,LVEF in both groups was higher than that before the implantation in this group,and LVEDD and LVESD were shorter than those before the implantation in this group,and BNP was lower than that before the implantation in this group;LVEF of(53.06±5.47)%in the experimental group was significantly higher than(48.45±5.11)%in the control group;the experimental group had LVEDD of(52.48±3.32)mm and LVESD of(49.07±3.56)mm,which were significantly smaller than(54.88±3.84)and(51.54±3.42)mm in the control group;BNP of(67.43±8.06)pg/ml in the experimental group was significantly lower than(82.18±8.84)pg/ml in the control group(P<0.05).After 6 months of implantation,the SF-36 score in both groups were significantly higher than that before the implantation in this group,and SF-36 score of(80.06±5.11)points in the experimental group were higher than(72.12±5.67)points in the control group(P<0.05).Conclusion Compared with right ventricular apex,right ventricular septum implantation can improve cardiac function and quality of life more effectively in patients with permanent cardiac pacemaker implantation.
