Characterization and Identification of Atrial Fibrillation Drivers in Patients with Non-Paroxysmal Atrial Fibrillation using Simultaneous Amplitude Frequency Electrogram Transform.

AF procedural termination sites harbored signal characteristics of repetitive, high frequency component of individualized electrogram during sinus rhythm, which can be masked by the low frequency fractionated electrogram and are difficult to see from the bipolar electrogram. Thus, SAFE-T mapping is feasible in identifying and characterizing sites of AF drivers. This article is protected by copyright. All rights reserved.
