摘要

目的:研究Marshall韧带在肺静脉触发性房颤中的作用。方法:20只犬随机分为Marshall韧带消融组（组1）及Marshall韧带假消融组（组2）各10只

建立肺静脉触发性房颤模型。组1Marshall韧带消融

组2Marshall韧带假消融后

两组均消融肺静脉。比较两组的电生理图

不应期

房颤诱发率差异。结果:组1经Marshall韧带消融后

房颤时心内电图示Marshall韧带及PV处电激动频率减慢

组2无变化。组1房颤诱发率在Marshall韧带消融前后分别为:84%±4%VS79%±4%

P=0.02;组2房颤诱发率在Marshall韧带假消融前后分别为:83%±4%VS80%±3%

P=0.11。肺静脉及消融后

组1房颤诱发率在肺静脉消融前后分别为:79%±4%VS42%±6%

P=0.00;组2房颤诱发率在肺静脉消融前后分别为:80%±3%VS47%±14%

P=0.00。组1房颤模型建立后

Marshall韧带消融后

肺静脉消融后不应期为:122±7VS136±9VS148±9

P<0.05

组2房颤模型建立后

Marshall韧带假消融后

及肺静脉消融后不应期为122±7VS131±8VS146±9

P<0.05。结论:肺静脉促发性房颤时Marshall韧带可能作为一个电连接通道或另一个促发点参与房颤发生发展。

Abstract

Objective:To study the role of the ligament of Marshall in atrial fibrillation arising at pulmonary veins. Methods:20 mongrel dogs were randomly divided into two groups(10 dogs in each group). Paroxysmal atrial fibrillation arising at the pulmonary veins was built in all dogs. After Ligament of Marshall ablation in group1

pulmonary vein ablation was performed in both group1 and 2. Epicardial electrograms

effective refractory period

and atrial inducibility were analyzed before and after two ablations. Results:The activation cycle length slowed down and atrial fibrillation inducibility was significantly decreased after the ligament of Marshall ablation in group1;atrial fibrillation inducibility were both decreased after pulmonary vein ablation. Conclusion:Ligament of Marshall might serve a electrical connections between pulmonary vein and left atrium or be another source of rapid activations in atrial fibrillation arising at the pulmonary veins.
