Temporally Stable Frequency Mapping and Ultra High-Density Voltage Map in Persistent Atrial Fibrillation Ablation

Objectives: The goal of this study was to retrospectively analyze the long-term outcome after persistent atrial fibrillation (AF) ablation by combining continuous wavelet transform (CWT) and left atrial (LA) voltage mapping. Background: CWT analysis is a frequency analysis to search the area of stable high frequency (stable pseudo frequency [sPF]) during AF. Methods: CWT analysis were performed in persistent AF (109 patients, 65{plus...
