背景资料：左心房低电压区的存在与肺静脉隔离（PVI）后房颤（AF）复发之间的相关性主要在持续性AF患者中显示。我们试图比较有和没有左心房低电压区的阵发性房颤患者的房颤复发率。方法：这项前瞻性观察性研究包括147例因阵发性房颤接受初始消融的连续患者。在窦性心律期间进行PVI后进行电压标测，低电压区被定义为双极峰-峰电压为
Background: Association between the presence of left atrial low-voltage areas and atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI) has been shown mainly in persistent AF patients. We sought to compare the AF recurrence rate in paroxysmal AF patients with and without left atrial low-voltage areas.Methods: This prospective observational study included 147 consecutive patients undergoing initial ablation for paroxysmal AF. Voltage mapping was performed after PVI during sinus rhythm, and low-voltage areas were defined as regions where bipolar peak-to-peak voltage was
