Abstract
Study of intracardiac electrograms (IEGMs) during atrial fibrillation (AF) provides clinically significant information that can be used in ablation therapy. Methods include determining a regional feature, e.g., dominant frequency (RDF), which encompasses the relationship between simultaneously recorded electrodes and identifies the feature components of a region, rather than the feature of a single electrode. Methods employing the regional feature may be used to identify and characterize variation and disorganization in wavefront propagation or wave breaks (WBs) at each recording site, and may be used to direct catheter ablation therapy.
