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.
