| 摘 要： | 为探索心房颤动的点状消融途径，选用健康犬以电刺激结合乙酰甲胆碱滴注的方法制成颤模型，以自制4对双极电极进行心外膜电生理标测，于心房易损性最大的部位进行射频消融治疗。结果表明，10只犬成功达到消融终点，与消融前相比，窦性心率、P波时限、校正窦房结恢复时间及房内传导时间变化均无显著性差异。提示阵发性房颤可通过点状消融得到消除，房颤的发生机制可能与激发活动有关。

| Abstract: | To investigate an approach of treatment for atrial fibrillation with discrete ablation lesion, 12 dogs with experimental atrial fibrillation underwent radiofrequency catheter ablation. Atrial lesion was made at the most vulnerable site. The results showed that in 10 of 12 dogs persistent fibrillation could be ablated. There was no significant change in sinus heart rate, P wave duration, and corrected sinoatrial node recovery time (cSNRT). The results suggested that paroxysmal atrial fibrillation could be eliminated by point ablation of the lesion, and that trigger activity might be involved in the mechanism of atrial fibrillation. |
