目的　双心室同步起搏已经被证明可有效改善充血性心力衰竭患者的心功能。进行双心室再同步治疗 (cardiacresynchronizationtherapy ,CRT)的技术关键是植入左心室导线。植入左心室导线技术难度大 ,操作复杂 ,有一定的并发症发生率 ,本文分析了 117例双心室起搏器植入术并发症。方法　充血性心力衰竭伴心室内阻滞患者 117例 ,其中男性 86例 ,女性 31例 ,平均年龄 (5 3 0 0±8 2 5 )岁。患者在进行逆行冠状静脉窦造影后 ,经冠状静脉窦插入导线至心脏静脉 (主要为心脏后静脉和侧后静脉 )进行左心室起搏。然后植入右心房和右心室电极导线。结果　 117例患者中 111例成功植入双心室起搏系统 ,成功率为 95 %。主要植入术的相关并发症包括 :冠状静脉窦夹层 4例(3 4 % % ) ,膈肌刺激需要重新植入 2例 (1 7% ) ;电极导线脱位 2例 (1 7% ) ,结论　双心室再同步治疗 (cardiacresynchronizationtherapywithbiventricularpacing)起搏器植入术有一定的术中并发症和一定的风险 ,术前应掌握好适应证并作好充分的准备 ,术中必须规范操作 ,严密观察 ,以减少并发症 Objective Biventricular pacing has been shown to be effective in improving cardiac function in patients with congestive heart failure. The key technique for cardiac resynchronization therapy (CRT) is the implantation of the left ventricular lead. Implantation of the left ventricular lead is technically challenging, complicated to operate, and has a complication rate. This article analyzed the complications of 117 biventricular pacemaker implants. Methods A total of 117 patients with congestive heart failure and ventricular block were enrolled, including 86 males and 31 females, with an average age of (5300 ± 825) years. Patients undergoing retrograde coronary sinus angiography, the coronary sinus insertion of wires to the heart vein (mainly the posterior venous and lateral veins) for left ventricular pacing. The right atrium and right ventricular lead were then implanted. Results Of the 117 patients, 111 cases were successfully implanted with biventricular pacing system with a success rate of 95%. The main complications related to implantation were: coronary sinus dissection in 4 cases (34%), diaphragm stimulation in 2 cases (17%), electrode lead dislocation in 2 cases (17%), conclusion double Cardiac resynchronization therapy with biventricular pacing Pacemaker implantation has some intraoperative complications and certain risks, preoperative indications should be well prepared and be fully prepared, the operation must be standardized, close observation to reduce complication
