摘要

随着肺静脉（PV）隔离的持久性提高，治疗非肺静脉（PV）病灶的重要性也在增加。我们描述了两例通过机械刺激和常规诱导在同一区域诱发非 PV 病灶的病例，消融术后无法诱发非 PV 病灶，这表明机械刺激和诱发非 PV 病灶之间存在关系。在一例复发的非房颤灶病例中，仅通过机械刺激诱发了房颤。对该区域进行消融术后，未发现复发。因此，用机械刺激法治疗房颤诱发部位可被视为治疗非房颤灶的有效方法。

Substrate Modification for Atrial Fibrillation Induced by Mechanical Irritation That May Be Associated With Non-Pulmonary Vein Foci.

The importance of treating non-pulmonary vein (PV) foci is increasing with improvements in the durability of PV isolation. We describe two cases wherein non-PV foci were induced by mechanical irritation and conventional induction in the same area, which was impossible to induce after ablation, suggesting a relationship between mechanical irritation and induction of non-PV foci. In a recurrent case of non-PV foci, atrial fibrillation (AF) was induced only by mechanical irritation. No recurrence has been observed since the ablation of the area. Thus, treatment of the AF induction site with mechanical irritation could be considered an effective therapy for non-PV foci.
