目的 探讨损伤电流(COI)与主动固定导线稳定性关系,为临床判断主动固定导线植入室间隔的可靠性和安全性提供依据.方法 入选按常规方法将主动固定导线植入右心室间隔患者193例,在导线螺旋旋出即刻测试COI,同时进行起搏参数测试.结果 按测得COI值分别为＜5 mV、5 ～10 mV、＞10 mV 3组,COI＜5 mV组平均(3.85±1.01) mV,COI 5～10 mV组平均(7.74±1.63) mV,COI＞10 mV组平均(10.63±0.55)mV.COI＜5 mV组阈值为(0.83±0.16)V,高于COI＞ 10 mV组阈值(0.69±0.15) V(P＜ 0.05),其余组间差异无统计学意义.COI＜5 mV组发生心室导线脱位2例,COI表现为“顶天立地”的发生心室导线穿孔1例.并发症的发生率为1.55％.结论 在室间隔起搏主动固定导线植入术中应测试COI,测得COI应至少在5 mV以上,但COI过大将增加导线穿孔的风险.
目的 探討損傷電流(COI)與主動固定導線穩定性關繫,為臨床判斷主動固定導線植入室間隔的可靠性和安全性提供依據.方法 入選按常規方法將主動固定導線植入右心室間隔患者193例,在導線螺鏇鏇齣即刻測試COI,同時進行起搏參數測試.結果 按測得COI值分彆為＜5 mV、5 ～10 mV、＞10 mV 3組,COI＜5 mV組平均(3.85±1.01) mV,COI 5～10 mV組平均(7.74±1.63) mV,COI＞10 mV組平均(10.63±0.55)mV.COI＜5 mV組閾值為(0.83±0.16)V,高于COI＞ 10 mV組閾值(0.69±0.15) V(P＜ 0.05),其餘組間差異無統計學意義.COI＜5 mV組髮生心室導線脫位2例,COI錶現為“頂天立地”的髮生心室導線穿孔1例.併髮癥的髮生率為1.55％.結論 在室間隔起搏主動固定導線植入術中應測試COI,測得COI應至少在5 mV以上,但COI過大將增加導線穿孔的風險.

Objective To determine whether current of injury(COI) magnitude is related to active fixation lead stability and safety.Methods One hundred ninety-three patients,undergoing active fixation lead implantation in our department,were enrolled.Current of injury and pacing parameters were recorded,when the spiral electrode spin out.Results Patients were divided into COI＜5 mV group、COI 5 ～ 10 mV group and COI＞10 mV group.The magnitude of COI＜5 mV group was (3.85 ± 1.01 ) mV,COI 5 ～ 10 mV group was (7.74±1.63) mV,and COI＞10 mV group was (10.63±0.55) mV.The threshold of COI＜5 mV group was (0.83±0.16) V,which was higher than the threshold of COI＞10 mV group [ (0.69±0.15) V,P＜ 0.05].Two ventricular lead dislodged acutely,and belonged to COI＜5 mV group.One ventricular lead perforated,whose COI magnitude was too high to be measured,requiring repositioning.Complication rate was 1.55％.Conclusion COI should be measured on active fixation lead implantation,and it at least Should be more than 5 mV.Too high COI magnitude may indicate perforation risk.
