摘    要:目的评价主动固定电极在右心室流出道间隔部起搏应用中的临床疗效和稳定性。方法55例有高度房室传导阻滞的缓慢心律失常患者随机分为2组,27例采用主动固定电极行右心室流出道间隔部起搏(主动固定电极组),28例采用被动固定电极行右心室心尖部起搏(被动固定电极组),比较2组电极植入时间和心电图QRS波宽度,电极植入时及随访起搏阚值、感知、阻抗,电极脱位及相关并发症。结果主动固定电极组的植入时间和X线曝光时间均长于被动固定电极组,(25.82±1.84)min vs (20.07±2.45)min、(15.75±1.99)min vs (8.50±1.89)min(均P〈0.05)。主动固定电极组起搏的ORS波时限较被动固定电极组短,(130.104±4.00)ms vs (152.30±10.80)ms(P〈0.05)。主动电极植入组即刻闽值比被动电极组高,(0.71±0.27)V vs (0.51±0.17)V(P〈0.01),术后随访3个月,2组的起搏阚值、感知差异均无统计学意义,术后3个月时主动电极组阻抗要低于被动电极组,(431.00±76.90)Ω vs (588.39±160.79)Ω(P〈0.01),未见电极脱位等并发症。结论主动固定电极在右心室流出道间隔部的起搏应用可行而稳定。

Abstract:Objective To evaluate the clinical efficacy and stability of right ventricular outflow tract(RVOT) pacing with the active fixation electrode in septal pacing.Methods Fifty patients with bradyarrhythmia implanted with pacemaker were randomly separated into two groups.One group underwent the RVOT ventricular septal pacing with the active fixation electrodes(active electrode group,n=27),the other group underwent the right ventricular apical pacing with the passive fixation electrodes(passive electrode group,n=...
