中文摘要:
      目的:观察主动电极在右室流出道间隔部起搏安全性和可行性?方法:80例需起搏器植入的患者,随机入组,采用VVI或DDD起搏模式,右室流出道间隔部起搏(RVOTS组)和右心室心尖部起搏(RVA组)各40例,观察两组在术中及术后的各项参数以及起搏心电图的QRS宽度?结果:两组患者均顺利完成手术,两组各1例术后发生电极脱位?全部手术无严重并发症出现?RVOTS组手术X 线曝光时间明显延长(19.8 ± 6.4 vs 10.3 ± 4.8,P < 0. 01);术中心室的起搏阈值RVOTS组高于RVA组(0.61 ± 0.23 vs 0.48 ± 0.17,P < 0. 05),但术后1个月及3个月无统计学差异,两组间阻抗?感知在术中及术后无统计学差异,起搏心电图QRS波宽度无统计学差异?结论:主动电极在右室流出道间隔部起搏是安全和可行的?
英文摘要:
      Objective:To investigate the safty and feasibility of active-fixation lead in patients with right ventricular outflow tract septum(RVOTS)pacing. Methods:Eighty patients were divided into two groups randomly. One group underwent the right ventricular outflow tract septum(RVOTS)with the active-fixation lead. The other group underwent the right ventricular apex(RVA)pacing with the passive-fixation lead. The parameters in and after operation of two groups were recorded and compared accordingly. Results:Operations went smoothly without complications in two groups. The active-fixation lead group had one case of wire dislocation,while the passive-fixation lead group also had one. Terms of X ray exposure time in active group were significantly longer than those in passive group(19.8 ± 6.4 vs 10.3 ± 4.8,P < 0. 01). After implantation of active electrode,the pacing thresholds were higher than those underwent passive electrode(0.61 ± 0.23 vs 0.48 ± 0.17,P < 0. 05). However,there was no difference between the two groups in pacing thresholds at one and three month point during follow-up. Pacing impedance and R-wave sensing between two groups had no significance. Meanwhile,there was no difference in the QRS duration between two groups. Conclusion:It is safe and feasible to pace in RVOTS with active electrode.
