Atrial fibrillation can be eliminated by a relatively new treatment called catheter ablation, which involves modification of the electrical properties of the heart using thin wires (catheters) passed up from the leg. Targeting areas where catheters record abnormal electrical activity improves results of catheter ablation, although it is uncertain what these recordings represent. The aim of this study is to characterize these abnormal electrical signals in an attempt to improve ablation outcomes.

心房纤颤可以通过一种相对较新的称为导管消融的治疗方法来消除，该方法包括使用从腿部向上传递的细导线（导管）来改变心脏的电特性。导管记录异常电活动的靶向区域改善了导管消融的结果，尽管不确定这些记录代表什么。本研究的目的是描述这些异常电信号的特征，以改善消融结果。
