摘要

左房后壁隔离期间经心外膜连接的左房后壁残余电位常为低频连续电位。通过三维电解剖制图系统准确标注这些剩余电位是具有挑战性的，并且可能会产生误导。在这里，我们提出了一个使用峰值频率分析成功隔离LAPW的案例。

Usefulness of peak frequency in Electrograms for elimination of left atrial Posterior Wall residual potentials via Epicardial connections

Left atrial posterior wall (LAPW) residual potentials via epicardial connections during LAPW isolation are often low-frequency continuous potentials. Accurate annotation of these residual potentials by three-dimensional electroanatomical mapping systems is challenging and can be misleading. Herein, we present a case of successful LAPW isolation using peak frequency analysis.
