研究目的: |
肺静脉隔离(PVI)已被公认为是心房颤动(AF)侵入性治疗的基石。单靠PVI治疗并不能治愈所有房颤,而且相当多的接受PVI治疗的患者仍有房颤复发的经历。因此,研究人员研究了其他消融策略以提高手术的长期有效性。其中一种策略涉及低压区(lva)的定位和修改。心房纤维化扰乱纤维束的连续性,并产生支持房颤起始和维持以及局部传导的底物扰动促进非均匀各向异性传导。左心房电压降低(LA)似乎是一个与纤维化相关的弥漫性过程。LVAs反映了左室弥漫性电压降低。既往研究有房颤下行低电压消融或窦性心律下低电压消融,不同心律下标测低电压区面积是有明显差异的,过度消融可能会导致其他心律失常,因此哪种心律下指导低电压区消融需要进一步研究。 |

Objectives of Study: |
Pulmonary vein isolation (PVI) is well established as the cornerstone for invasive treatment of atrial fibrillation (AF). PVI alone does not cure all AF, and a significant number of patients undergoing PVI still experience AF recurrence. As a result, additional ablation strategies have been studied to augment long-term effectiveness of the procedure. One such strategy involves localization and modification of low voltage areas (LVAs). Atrial fibrosis disturbs fiber bundle continuity and creates substrate to support initiation and maintenance of AF and local conduction disturbances promote non-uniform anisotropic conduction. Voltage reduction in the left atrium (LA) seems to be a diffuse process associated with fibrosis. LVAs reflect diffuse voltage reduction in the LA. Previous studies have conducted low-voltage ablation in atrial fibrillation downlink or subsinus arrhythmia. There are significant differences in the area of low-voltage zone measured by different subrhythms, and excessive ablation may lead to other arrhythmias. Therefore, further research is needed on which rhythm guides ablation in low-voltage zone. |
