Termination of atrial fibrillation by catheter ablation can be successfully predicted from baseline ECG

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

Several organization indices have been used to predict the outcome of stepwise catheter ablation (step-CA) in long-standing persistent atrial fibrillation (LS-pAF), however with limited success. Our study aims at developing innovative indices from baseline ...

OCULAR ARTIFACT REMOVAL FROM EEG: A COMPARISON OF SUBSPACE PROJECTION AND ADAPTIVE FILTERING METHODS

Touradj Ebrahimi, Jean-Marc Vesin, Ashkan Yazdani, Eleni Kroupi

One of the fundamental challenges in EEG signal processing is the selection of a proper method to correct ocular artifacts in the recorded electroencephalogram (EEG). Several methods have been proposed for this task. Among these methods, two main categorie ...

P-wave Indices to Detect Susceptibility to Atrial Fibrillation

Jean-Marc Vesin, Andréa Buttu

The aim of this work is to present different markers resulting from the analysis of a single ECG lead recorded during sinus rhythm. To this purpose, the ECGs from three populations were compared: healthy subjects, patients subject to paroxysmal AF selected ...

A New Method for ECG Tracking of Persistent Atrial Fibrillation Termination during Stepwise Ablation

Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot

Stepwise radiofrequency catheter ablation (step-CA) has become the treatment of choice for the restoration of sinus rhythm (SR) in patients with long-standing persistent atrial fibrillation (pers-AF). Its success rate appears limited as the amount of ablat ...

Study of the effect of rapid pacing of atrial fibrillation on the non-paced atrium

Jean-Marc Vesin, Lukas Kappenberger, Laurent Renaud Uldry

Purpose: Experimental studies showed that local capture of atrial fibrillation (AF) by rapid pacing was possible in humans. However, contradictory observations were reported on its effect at distant atrial sites. The present model-based study investigated ...

Novel complexity measurements in the ECG differentiate persistent from permanent atrial fibrillation

Jean-Marc Vesin, Lukas Kappenberger, Laurent Renaud Uldry, Jérôme Sébastien Van Zaen

Purpose: Distinguishing persistent from permanent atrial fibrillation (AF) in a reliable way would improve AF patient management, as cardioversion options could be considered appropriately. In this study, complexity measures based on the combined analysis ...

Mechano-electrical contribution of ventricular contractions to the complexity of atrial fibrillation electrograms

Jean-Marc Vesin, Andréa Buttu, Sarah Volorio, Etienne Pruvot

Purpose: Intracardiac organization indices (OI) have been used to track the efficiency of stepwise radiofrequency catheter ablation (step-CA) of persistent atrial fibrillation (pers-AF). A better understanding of the components and complexity of AF electro ...

Morphological Study of Intracardiac Signals as a New Tool to Track the Efficiency of Stepwise Ablation of Persistent Atrial Fibrillation

Jean-Marc Vesin, Andréa Buttu, Etienne Pruvot

Intracardiac organization indices such as atrial fibrillation (AF) cycle length (AFCL) have been used to track the efficiency of stepwise catheter ablation (step-CA) of longstanding persistent AF, however with limited success. The morphology of AF activati ...

Tracking of Stepwise Ablation of Persistent Atrial Fibrillation using Synchronization of nearby Electrograms

Jean-Marc Vesin, Andréa Buttu, Sarah Volorio, Etienne Pruvot

Purpose: The timing of bipolar intracardiac electrograms (EGMs) during atrial fibrillation (AF) reflects the dynamics of AF wavelets. The extent of synchronization between EGMs is an indirect measure of AF spatial organization. Our study intends to determi ...

Susceptibility to Paroxysmal Atrial Fibrillation: A Study using Sinus Rhythm P Wave Parameters

Lam Dang, Jean-Marc Vesin, Lukas Kappenberger

Early recognition of patients at high risk for atrial fibrillation may help to minimize potential health risks. The detection of susceptibility to develop atrial fibrillation is thus a real clinical challenge. Whereas many studies have used the signal-aver ...

Optimizing Local Capture of Atrial Fibrillation by Rapid Pacing: Study of the Influence of Tissue Dynamics

Vincent Jacquemet, Jean-Marc Vesin, Lukas Kappenberger, Laurent Renaud Uldry

While successful termination by pacing of organized atrial tachycardias has been observed in patients, rapid pacing of AF can induce a local capture of the atrial tissue but in general no termination. The purpose of this study was to perform a systematic e ...
