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 ...

Arrhythmia - Atrial Fibrillation (AF)- Case Study
Atrial Fibrillation (AF) is often described as an irregularly irregular rhythm. AF is an arrhythmia with no consistent ventricular response or pattern due to its somewhat random and chaotic discharging of atrial impulses firing disconnectedly from multiple foci. This continuous and erratic behavior results in a ventricular response that changes from beat to beat. AF will typically present with a ...

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 ...
