摘要 目的:评价右心室间隔部与心尖部起搏对心室同步性及患者预后的影响。方法:将入选患者分为右心室心尖部组(RVA组)和右心室间隔部组(RVS组),比较两组患者手术情况、手术前后QRS波宽度、左心室射血分数(LVEF)、左室大小及主要不良心血管事件发生。结果:RVS组与RVA组电极导线植入时间、X线曝光时间差异无统计学意义(P>0.05)。与RVA组比较,术后RVS组左室有所缩小,起搏时QRS宽度明显变窄,差异有统计学意义。其主要不良心血管事件减少。结论:RVS起搏尽可能地维持了双心室的正常激动顺序和双心室的同步性,比RVA起搏更能改善患者预后。 Objective:To evaluate the effect of ventricular synchrony and prognosis of patients with spiral electrode pacing between right ventricular septal and right ventricular apical.Method:Patients were divided into spiral electrode pacing right ventricular apical group(RVA group)and right ventricular septal(RVS group).Two groups were compared with preoperative and postoperative QRS,left ventricular ejection fraction(LVEF)and left ventricular size.Result:RVS group and RVA group electrode wires implanted time and the X-ray exposure time were no significant different(P〉0.05).Compared with RVA group,the left ventricle,QRS duration,and main cardiovascular events were decreased in RVS group.Conclusion:RVA pacing causes left and right ventricular dyssynchrony.RVS pacing maintains the normal activation sequence and synchronization of biventricular as much as possible,and improves patient prognosis than RVA pacing.
