摘　　要：目的探讨右室间隔部(ROVT)起搏和右室心尖部起搏对心室心功能的影响。方法 150例完全房室传导阻滞置入单腔起搏器的患者,随机分成右室间隔(RVOT)起搏组(n=78)和右室心尖部(RVA)起搏组(RVA组n=72)。分别测量两组术前和术后6个月、1年的左室收缩末内径(LVESD)、左室舒张末径(LVEDD)、左室射血分数数(LVEF)、每搏量(SV)及BNP、QRS宽度。结论 ROVT起搏较RVA起搏更有利于了保证心室收缩的同步性,符合生理性起搏,改善心功能。Objective To evaluate the effects on ventricular cardiac function between the right ventricular interval department（ROVT）pacemaker and the right ventricular apex pacemaker. Methods 150 patients with complete atrioventricular block have installed single chamber pacemaker, randomly divided into groups of right ventricular interval pacemaker n=78）and right ventricular apex（RVA）pacemaker group（n=72）. The two groups were measured left ventricular con traction diameter（LVESD）, left ventricular end diastolic diameter （LVEDD）, left ventricular ejection ffaction（LVEF）, stroke volume（SV） and BNP, QRS breadth before operation,and postoperation 6 months, I year. Conclusion ROVT group is more advantageous to the guarantee of ventricular systolic synchronicity than RVA group, conforms to the physiological pacemaker, improve heart function.
