摘　　要：目的探讨更简捷、实用、安全的右心室流出道间隔部主动固定起搏的导线定位方法。方法入选142例患者．随机分为两组。研究组70例采用间隔部心室起搏导线的双弯塑形钢丝定位法，对照组72例采用常规单弯J形钢丝辅助定位法。观察两组患者起搏导线参数（感知、阈值、阻抗）、间隔部起搏导线定位成功率、心室起搏导线植入手术时间、X线曝光时间、手术并发症及导线脱位情况。结果两种导线定位方法对起搏导线参数无明显影响。两组起搏导线一次定位成功率（70．0％、50．7％）、累计成功率（96．0％、89．0％）、X线曝光时间[（13．5±5．9）min、（20．3±9．6）min]差异均有显著性意义（P〈0．05）。两组患者术后随访6月，均未见起搏导线脱位及起搏参数异常改变。结论采用双弯塑形钢丝方法可明显提高流出道间隔部主动固定起搏导线定位成功率，明显缩短X线曝光时间。Objective To explore one operation method of pacing electrode location that is safe, quickly, practical in right ventricular outflow septum cardiac pacing. Methods 142 patients were enrolled, They were randomized into two groups. Doubte-curve guiding wire was used in study group （70 cases）,routine mono-curve guiding wire was used in control group （ 72 cases）.The results of pacing parameter, success rate, operation time and complications between two groups. Results There were no significant difference in pacing parameter, The rates of once and summary successful RVOT location were 70.0% and 96.0% in study group vs 50.7% and 89.0% in control group. There were significant difference in the rates of once and summary successful between two groups. While there were significant difference in X-ray exposing time between study group and contror group （ 13.5± 5.9 vs 20.3 ± 9.6 min,P〈 0.05）. Complications didn＇t happened in all patients. Conclusion The operation of RVOT electrode location in double-curve guiding wire might be much easier, quicker and practical than that of in routine guiding wire and also with shorter X-ray exposing time.
