A Computational Study of the Electrophysiological Substrate in Patients Suffering From Atrial Fibrillation

In the context of cardiac electrophysiology, we propose a novel computational approach to highlight and explain the long-debated mechanisms behind atrial fibrillation (AF) and to reliably numerically predict its induction and sustainment. A key role is pla ...

Nanovolcano microelectrode arrays: toward long-term on-demand registration of transmembrane action potentials by controlled electroporation

Philippe Renaud, Arnaud Bertsch, Benoît Xavier Emmanuel Desbiolles, Nicolas Grégoire Maïno, Stephan Rohr, Etienne de Coulon

Volcano-shaped microelectrodes (nanovolcanoes) functionalized with nanopatterned self-assembled monolayers have recently been demonstrated to report cardiomyocyte action potentials after gaining spontaneous intracellular access. These nanovolcanoes exhibit ...

Cardio-Respiratory Characterization of the Autonomic Balance

Jean-Marc Vesin, Leila Mirmohamadsadeghi, Grégoire Millet

The autonomic balance is often measured using the low frequency~(LF) and high frequency~(HF) powers of the heart beat-to-beat intervals. However, these indices do not adequately integrate the influence of respiration and have been widely criticized. We stu ...

Biochemical and biophysical approaches to study the structure and function of the chloride channel (ClC) family of proteins

Henning Paul-Julius Stahlberg

The chloride channel (ClC) protein family comprises both chloride (Cl-) channels and chloride/proton (Cl/H+) antiporters. In prokaryotes and eukaryotes, these proteins mediate the movement of Cl- ions across the membrane. In eukaryotes, ClC proteins play a ...

Right insular damage decreases heartbeat awareness and alters cardio-visual effects on bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Roberta Ronchi, Javier Bello Ruiz, Marta Lukowska

Recent evidence suggests that multisensory integration of bodily signals involving exteroceptive or interoceptive information modulates bodily aspects of self-consciousness such as self-identification and self-location. In the so-called full body illusion ...

Activity Level of an Atrial Ectopic Focus Observed Through the Equivalent Dipole: a Biophysical Model

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene, Vincent Jacquemet

Quantifying the role of atrial ectopic foci in the initiation and the maintenance of atrial fibrillation (AF) is a relevant clinical problem. This study aims at assessing the relation between the activity level of an ectopic focus and the complexity of the ...

Atrial Repolarization Alternans in a Chronic Sheep Model of Pacing-Induced Atrial Fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

In pacing-induced models of atrial fibrillation (AF) that mimic atrial high-frequency foci, the increase in AF susceptibility over time is not paralleled by any increase in dispersion of repolarization (DOR). Measurements of effective refractory periods (E ...
