Stepwise Localization of Non‐Pulmonary‐Vein Ectopy Using Cycle‐Length‐Based Activation Map Separation and Local Electrogram Morphology on the Affera System
By Suguru Nishiuchi, Shingo Yoshimura, Takehito Sasaki and 2 others.
Abstract
On the Affera system, a single voltage-map dataset containing both sinus and ectopic beats, collected without rhythm-specific settings, can be separated by cycle length (coupling interval) into SR and PAC activation maps. Stepwise filtering by activation threshold (voltage-per-second, excluding far-field potentials) and close-unipolar QS-like morphology then precisely localizes the ectopic origin.
