Extracting Atrial Activations from Intracardiac Signals during Atrial Fibrillation using Adaptive Mathematical Morphology

Jean-Marc Vesin, Etienne Pruvot, Sasan Yazdani, Andréa Buttu

The detection of intracardiac activities is a major issue in the processing of atrial fibrillation signals. we evaluate a method based on mathematical morphology with an adaptive structuring element in order to extract the atrial activations from intracard ...

Vortex lattice structure in BaFe2(As0.67P0.33)(2) via small-angle neutron scattering

Jonathan White

We have observed a magnetic vortex lattice (VL) in BaFe2(As0.67P0.33)(2) (BFAP) single crystals by small-angle neutron scattering. With the field along the c axis, a nearly isotropic hexagonal VL was formed in the field range from 1 to 16 T, and no symmetr ...

Influence of atrial substrate on local capture induced by rapid pacing of atrial fibrillation

Jean-Marc Vesin, Vincent Jacquemet, Alexandru Rusu

Preliminary studies showed that the septum area was the only location allowing local capture of both the atria during rapid pacing of atrial fibrillation (AF) from a single site. The present model-based study investigated the influence of atrial substrate ...

Adaptive frequency tracking of the baseline ECG identifies the site of atrial fibrillation termination by catheter ablation

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

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

Kinetics of Atrial Repolarization Alternans in a Free-Behaving Ovine Model

Jean-Marc Vesin, Etienne Pruvot, Florian Jousset

Kinetics of Atrial Repolarization Alternans. Introduction: Repolarization alternans (Re-ALT), a beat-to-beat alternation in action potential repolarization, promotes dispersion of repolarization, wavebreaks, and reentry. Recently, Re-ALT has been shown to ...

Measures of spatiotemporal organization differentiate persistent from long-standing atrial fibrillation

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

This study presents an automatic diagnostic method for the discrimination between persistent and long-standing atrial fibrillation (AF) based on the surface electrocardiogram (ECG). Standard 12-lead ECG recordings were acquired in 53 patients with either p ...

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

Jean-Marc Vesin, Etienne Pruvot, Andréa Buttu, Jérôme Sébastien Van Zaen, Alain Manuel Viso Rocha

Purpose Multiple organization indices (OIs) have been used to predict the outcome of stepwise catheter ablation (step-CA) in long-standing persistent AF (pers-AF), however with limited success. Our study aims at developing innovative OIs from baseline (BL, ...
