| 摘 要： | 目的:初步探讨右室间隔起搏(RVSP)和右室心尖部起搏( RVAP)对完全房室传导阻滞( CAVB) 患者心功能的影响。方法:87例因CAVB植入起搏器的患者, 其中45例行RVSP术(RVSP组),42例行RVAP术(RVAP组),分别对术前及术后6、12和18个月,患者的QRS波时限、左室舒张末内径（LVEDD）、 左室射血分数（LVEF）、每搏量（SV）、心脏指数（CI）、加速度指数（ACI）进行检查比较。结果:所有患者均完成12个月随访, 79例完成18个月随访。术后RVAP组QRS波时限较RVSP组明显增宽(P<0.05),术后12个月RVAP组LVEF、SV、ACI均较RVSP组明显降低(P<0.05),术后18个月RVAP组LVEDD较RVSP组明显增大(P<0.05),RVAP组CI均较RVSP组降低,但尚未达到显著性差异。结论:RVSP较RVAP有利于CAVB患者心功能的保护。

Effect of right ventricular septal pacing and right ventricular apical pacing on heart functions in patients with complete atrioventricular block: a comparative study |
| |
| Abstract: | AIM:To compare the effects of right ventricular septal pacing (RVSP) and right ventricular apical pacing (RVAP) on heart functions in patients with complete atrioventricular block (CAVB). METHODS: Eighty-seven CAVB patients with implanted pacemakers were enrolled in this study. Patients were divided into RVSP group (n=45) and RVAP group (n=42). QRS duration, LVEDD, LVEF, SV, CI and ACI were measured before implantation and 6, 12 and 18 months after implantation. RESULTS: QRS duration in RVAP group was longer than in RVSP group (P<0.05). LVEF, SV and ACI in RVAP group decreased compared with those in RVSP group 12 months after implantation (P<0.05). LVEDD in RVAP group increased compared with that in RVSP group 18 months after implantation (P<0.05). CI in RVAP group decreased, but no significant difference was found between groups 18 months after implantation. CONCLUSION: Right ventricular septal pacing (RVSP) is good in protecting cardiac function in patients with CAVB compared with right ventricular apical pacing (RVAP). |
