Velocity characteristics of atrial fibrillation sources determined by electrographic flow mapping before and after catheter ablation
Background: Electrographic-Flow-(EGF)-Mapping is a novel method to identify Atrial Fibrillation (AF) drivers. Sources of excitation during AF can be characterized and monitored. Objective: The aim of this study was to evaluate the correlation between velocity of EGF around a respective AF source and its spatial variability (SV) and stability (SST). Methods: 25 patients with AF were included in ...

Identification of active atrial fibrillation sources and their discrimination from passive rotors using electrographical flow mapping
Barbara Bellmann 1, Tina Lin 2, Peter Ruppersberg 3, Marit Zettwitz 1, Selma Guttmann 1, Verena Tscholl 1, Patrick Nagel 1, Mattias Roser 1, Ulf Landmesser 2, Andreas Rillig 4 Background: The optimal ablation approach for the treatment of persistent atrial fibrillation (AF) is still under debate; however, the identification and elimination of AF sources is thought to play a key role. Currently ...

First-in-man demonstration of 18-month spatiotemporal stability of active atrial fibrillation source detected by Electrographic Flow mapping in persistent atrial fibrillation
Keywords: atrial fibrillation, catheter ablation, mapping, atrial fibrillation, source, electrographic flow Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue. The aim of this ...
