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

ABSTRACT: 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.
