Continuous monitoring and quantification of multiple parameters of daily physical activity in ambulatory Duchenne muscular dystrophy patients

Kamiar Aminian, Anisoara Ionescu, Bijan Najafi

Multiple motor function and strength assessment tools exist for the evaluation of neuromuscular diseases, but most do not directly assess functional ability in the patients' daily physical activity in their home environment. In this study our aim was to as ...

Cardiac ablation, How Contact Force influences lesion quality

Olivier Frémont

Cardiac ablation is a worldwide accepted minimally invasive procedure to treat Atrial Fibrillation (AF). It consists in creating lesions with a catheter in the cardiac tissue in order to cut off specific electrical pathways. During this project, based on p ...

Rate-dependence of 2:1 atrial capture as a protective mechanism against atrial tachycardia-induced atrial fibrillation

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

We recently observed periods of intermittent 2:1 atrial capture in the human left atrium (LA), preceded by atrial repolarization alternans during pacing-induced atrial tachycardia (PIAT). The mechanism involved in resumption of 1:1 atrial capture remains u ...

Application of the fastest route algorithm in the interactive simulation of the effect of local ischemia on the ECG

A method is described to determine the effect on the ECG of a reduced propagation velocity within an ischemic zone. The method was designed to change the activation sequence throughout the ventricles interactively, i.e. with a response time in the order of ...

Dictionary learning for the sparse modelling of atrial fibrillation in ECG signals

Pierre Vandergheynst, Jean-Marc Vesin, Rémi Gribonval

We propose a new method for ventricular cancellation and atrial modelling in the ECG of patients suffering from atrial fibrillation. Our method is based on dictionary learning. It extends both the average beat subtraction and the sparse source separation a ...

The Role of Atrial Modeling in the Development of ECG Processing Tools

Jean-Marc Vesin, Mathieu Lemay, Laurent Renaud Uldry, Cédric Duchene, Vincent Jacquemet, Lukas Kappenberger

The standard ECG remains the most common non-invasive tool for assessing atrial fibrillation. Specific signal processing techniques have been developed to improve the diagnosis. However, validation of such tools is challenging and comprehensive invasive da ...

Left ventricular hypertrophy induced by reduced aortic compliance

Nikolaos Stergiopoulos, Nico Westerhof

It was the aim of this study to investigate the long- term effects of reduced aortic compliance on cardiovascular hemodynamics and cardiac remodeling. ...

In-Vivo Measurements of Atrial Repolarization Alternans Based on Standard Pacemaker Technology

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: It has been shown that repolarization alternans (Re-ALT), a beat-to-beat alternation in action potential duration, enhances dispersion of repolarization DOR above a critical heart rate and promotes susceptibility to ventricular arrhythmias. I ...

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 ...

The MRL mouse repairs both cryogenic and ischemic myocardial infarcts with scar

Yann Barrandon, Lukas Kappenberger, Hans-Anton Lehr

Objective: The MRL mouse strain shows extraordinary wound healing capacities. Some years ago, Leferovich et al. (Proc Natl Acad Sci U. S. A. 2001;98:9830-35) have reported the absence of scar formation after cryogenically-induced right ventricular myocardi ...
