摘要
目的 :研究阻断 Bachmann束 (BB)对心房颤动 (AF)诱发的影响。方法 :对 10只实验犬行心外膜 BB射频消融术。阻断 BB前后分别从左右心耳行快速短阵刺激以诱发 AF,并比较 AF阈值与持续时间。结果 :在刺激方式与强度相同的情况下阻断 BB前后 AF阈值与持续时间相差无统计学意义 (P>0 .0 5 )。结论 :阻断 BB对 AF诱发率无明显影响 ,提示在
AIM: To compare with the incidences of induced atrial fibrillation (AF)before and after blocking of Bachmann bundle (BB), and to evaluate the role of BB in initiation and maintaince of AF. METHODS: Ten dogs' BB were blocked by epicardial radiofrequency ablation and the blocking was confirmed by histopathologic examination. Burst stimuli from right and left auricles were given to induce AF. RESULTS: The differences of AF thresholds and AF duration before and after blocking of BB were not statistically significant ( P >0.05). CONCLUSION:Blocking of BB not influence the initiation of AF.
