Abstract

We experienced a rare case of atrial flutter originating from the giant left appendage (LAA). The local potential of the ablation catheter presented with a rare finding, appearing up to 185 ms earlier than the surface P-wave in the distal LAA. With thoracoscopic LAA clipping, tachycardia was successfully controlled.

摘要

我们遇到了一例罕见的起源于巨大左心耳（LAA）的心房扑动病例。消融导管的局部电位呈现出一个罕见的发现，在LAA远端比体表P波提前出现达185毫秒。通过胸腔镜下LAA夹闭术，心动过速得到了成功控制。
