目的研究12通道心电生理记录仪在左房环状线性(线)消融、肺静脉口节段性(段)电隔离术加局灶性(点)消融法(简称线-段-点法)治疗心房纤颤(房颤)中的作用。方法使用12通道心电生理记录仪,在双Lasso电极标测下分别在左房环状线性消融左右侧上下肺静脉口周围,肺静脉口壶腹部节段性消融丛状电位,最后标测和点状消融提前的单相电位(在肺静脉内或心房内和腔静脉口)。结果26例患者均行肺静脉开口外环状线性消融。电隔离肺静脉共89条。行点状消融共25例。26例中20例所有异常电位消失,6例肺静脉内仍有高耸的异常电位,但已达到传出阻滞。手术即刻成功率100%。随访4～8个月,24例(92%)未发作房颤;2例(8%)术后仍有房颤发作,服用抗心律失常药物后房颤发作明显减少。所有病例未发生并发症。结论采用12通道心电生理记录仪能够达到“线-段-点联合消融法”治疗房颤的要求,方法简单,成功率高,是目前我国大多数医院所具备的常规电生理检测仪。
Objective To study the effects of 12-channel electrocardiograph on left atrial circular linear (ablation), segmental pulmonary vein (segmental) electrical isolation and focal ablation (line-segment-point method) Atrial fibrillation (atrial fibrillation) in the role. Methods Using a 12-channel electrocardiograph, we measured the ablation potentials of the ampulla around the pulmonary veins around the left and right pulmonary vein around the left atrium by linear double ablation, Ablation of the pre-single-phase potential (in the pulmonary vein or in the atrium and vena cava). Results All the 26 patients underwent linear annular ablation of the pulmonary veins. Electrical isolation of pulmonary vein a total of 89. Point punctate ablation a total of 25 cases. All of the 20 cases in 26 cases disappeared, and the abnormal anomalous potentials still remained in 6 cases of pulmonary veins, but the block was reached. Immediate success rate of 100% surgery. Atrial fibrillation was not found in 24 cases (92%) after 4 to 8 months of follow-up. Atrial fibrillation occurred in 2 patients (8%) after operation, and the incidence of atrial fibrillation was significantly decreased after taking anti-arrhythmic drugs. No complications occurred in all cases. Conclusions The 12-channel electrophysiological recorder can meet the requirements of “line-segment-point combined ablation” for atrial fibrillation. The method is simple and has a high success rate. It is the most common electrophysiological detector available in most hospitals in our country.
