摘　　要：多数研究将低电压区(low-voltage areas,LVA)定义为窦性心律下双极电压≤0.5 mV的心房区域。目前的研究发现,LVA主要反映了心肌纤维化的程度与分布,且LVA与碎裂电位(complex fractionated atrial electrograms,CFAE)、转子间的空间分布可能相关。对于在窦性心律或房颤下标测到LVA的患者,在传统肺静脉隔离(pulmonary vein isolation,PVI)的基础上联合LVA针对性消融,可能比单纯PVI更有利于降低房颤的远期复发率。本文就低电压区指导心房颤动导管消融的研究进展进行综述。Most studies define the cutoff value for left atrial low voltage areas(LVA)as a bipolar voltage≤0.5 mV measured during sinus rhythm.Current research has found that LVA mainly reflects the degree and distribution of atrial fibrosis and LVA may be related with the spatial distribution of complex fractionated atrial electrograms(CFAE)and rotors.Ablation of LVA combined with traditional pulmonary vein isolation(PVI)may better reduce the long term recurrence rate of atrial fibrillation compared with pulmonary vein isolation alone.This article reviews the progress in LVA to guide atrial fibrillation ablation.
