| ［摘要］目的 评价低位房间隔起搏的可行性与安全性，并探讨一种简化的起搏导线定位方法．方法 选择符合起搏器植入适应证48例病态窦房结患者，随机分成2组，一组患者（n＝24例）采用经过简化塑型导丝引导主动固定起搏导线行低位房间隔定位起搏；另外一组患者（n＝24例）采用传统被动固定起搏导线行右心耳起搏．观察两组患者心房起搏导线植入时间，植入成功率，测试起搏器植入即刻、术后1周、1月及3月起搏相关参数；观察起搏器植入相关并发症（电极脱位，起搏器囊袋感染，积血及心包积液）．结果 LAS组心房起搏导线定位成功21例，3例失败，RAA组心房导线全部定位成功．LAS组平均心房起搏导线定位成功时间为6.3±0.8 min （3～15.5 min），显著长于RAA组患者（3.5±0.5）min（1.2～8.3）min．术中即刻，术后1周、1月及3月的各项起搏参数均稳定，2组间未见显著差异．随访3月期间2组患者均为发生起搏器植入相关并发证．结论 双弯J行导丝的简化设计可协助低位房间隔主动固定起搏导线的成功定位，同时证实应用主动固定起搏导线实施低位房间隔是安全，可行的． |

| ［Abstract］Objective To evaluate the feasibility and safety of low atrial septum pacing， and investigate a simplified location methods for low atrial septum pacing. Methods Forty eight patients with pacemaker implantation standard，were randomly divided into two groups. Group A（n＝24）with low atrial septum pacing by active fixation electrode（LAS group），and group B（n＝24）with traditional right atrial appendage pacing by electrode passive fixation（RAA group）. The atrial electrode operating time， the success rate of implantation were recorded，and the pacing parameters were measured in first week，first months and third months after operation，and associated complications including electrode dislocation，pace pocket infection and blood，pericardial effusion was observed. Results There were 21 cases success in atrial electrode location operation and 3 cases of failure in LAS group， while all operations were completed successfully in RAA group. Atrial electrode operation time had significant difference between two groups. The operate time of LAS group was longer than that of RAA group（6.3±0.8 min vs 3.5±0.5 min，P <0.05）. Pacing parameters remained stable during operation and on the first week，first and third months post-operative， and no significant differences existed between the two groups. No complications occurred during 3 months follow up. Conclusion The new simplified design technique of J shape duo-curve guide wire could increase the success rate of low atrial septum pacing. Low atrial septum pacing through active fixation electrode is safe and feasible. |
