背景房颤（AF）消融后残留的心房致心律失常基质导致复发性房性快速性心律失常。在AF患者中，振幅降低的电描记图表明患病myocardial.Objective本研究的目的是探讨低电压区的分布和诱导房性快速性心律失常的类型之间的关联。方法我们的前瞻性观察性研究纳入了152例连续AF患者计划进行初始消融（46%持续性AF）。肺静脉电隔离后，在窦性心律时进行电压标测，
BACKGROUND Recurrent atrial tachyarrhythmias occur as a result of residual atrial arrhythmogenic substrates after atrial fibrillation (AF) ablation. In patients with AF, electrograms with reduced amplitudes indicate diseased myocardium.OBJECTIVE The purpose of this study was to investigate the association between the distribution of low-voltage areas and the type of induced atrial tachyarrhythmias.METHODS Our prospective observational study enrolled 152 consecutive AF patients scheduled for an initial ablation (46% persistent AF). After pulmonary vein isolation, voltage mapping was performed during sinus rhythm, and regions with reduced electrogram amplitudes (
