Therapeutic Strategies for the Treatment of Atrial Fibrillation

Atrial fibrillation is the most common cardiac rhythm disorder encountered in clinical practice, often leading to severe complications such as heart failure and stroke. This arrhythmia, increasing in prevalence with age, already affects several millions of ...

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

Jean-Marc Vesin, Lam Dang, 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 ...

Long-term intermittent atrial tachycardia decreases activation recovery interval, flattens its kinetics and blunts its rate dependence before sustained atrial fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: We recently observed in an acute ovine model of pacing-induced atrial tachycardia (PIAT) that rapid atrial capture and fibrillatory conduction were prevented by 2:1 capture mediated by decreased excitability. We hypothesize that long-term int ...

ECG-based prediction of atrial fibrillation development following coronary artery bypass grafting

Sinisa Sovilj

In patients undergoing coronary artery bypass grafting (CABG) surgery, post-operative atrial fibrillation (AF) occurs with a prevalence of up to 40%. The highest incidence is seen between the second and third day after the operation. Following cardiac surg ...

A finite volume scheme for cardiac propagation in media with isotropic conductivities

Ricardo Esteban Ruiz Baier

A finite volume method for solving the monodomain and bidomain models for the electrical activity of myocardial tissue is presented. These models consist of a parabolic PDE and a system of a parabolic and an elliptic PDE, respectively, for certain electric ...

Decreased Excitability as a Protective Mechanism Against Repolarization Alternans-Induced Atrial Reentry

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: We recently observed in human left atrium periods of intermittent 2:1 and 1:1 atrial capture, preceded by atrial repolarization alternans (Re-ALT) during rapid pacing. It remains undetermined whether Re- ALT plays a role in preventing 1:1 atr ...

Melanocyte-like cells in the heart and pulmonary veins contribute to atrial arrhythmia triggers

Friedrich Beermann, Fang Liu

Atrial fibrillation is the most common clinical cardiac arrhythmia. It is often initiated by ectopic beats arising from the pulmonary veins and atrium, but the source and mechanism of these beats remains unclear. The melanin synthesis enzyme dopachrome tau ...

Estimation of Atrial Multiple Reentry Circuits from Surface ECG Signals based on a Vectorcardiogram Approach

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene

This paper presents a simulation study on the identifiability of multiple reentrant circuits on the basis of the vectorcardiogram. The methods involved include an advanced tracking of the basic frequencies of the dominant rotors and a supporting identifica ...

Adaptive Multiple Frequency Tracking Algorithm: Detection of Stable Atrial Fibrillation Sources from Standard 12-Lead ECG

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

The detection of stable atrial fibrillation (AF) sources remains one of the major challenges in the AF management. In this study, we investigated the feasibility of detecting stable AF sources from (non invasive) data simulated by means of numerical proced ...
