Je suis offensé! : Ce n’est pas parce qu’un sujet est sensible qu’il ne doit pas être abordé
I’m Offended! : Because an issue is sensitive doesn’t mean it shouldn’t be discussed

Equivalent dipole sources to estimate the influence of extracellular myocardial anisotropy in thin-walled cardiac forward models
(Elsevier, 2017)The extracellular domain of the heart is anisotropic, which affects volume conduction and therefore body surface potentials. This paper tests the hypothesis that when wall thickness is sufficiently small (such as in the atria), the effect of extracellular ... -
A simple analytical model of action potential duration profile in electrotonically-coupled cells
(Elsevier, 2016)Electrotonic interactions between cardiac cells modulate the dispersion of action potential duration (APD). This paper provides a complete mathematical analysis of a simple model of exponential-shaped repolarization in a network of electrotonically-coupled ... -
QT interval measurement and correction in patients with atrial flutter : a pilot study
(Elsevier, 2014)Background and Purpose Measurement of QT intervals during atrial flutter (AFL) is relevant to monitor the safety of drug delivery. Our aim is to compare QT and QTc intervals in AFL patients before and after catheter ablation in order to validate QT ... -
Assessment of the sensitivity of detecting drug-induced QTc changes using subject-specific rate correction
(Elsevier, 2012)Aims To quantify the sensitivity of QT heart-rate correction methods for detecting drug-induced QTc changes in thorough QT studies. Methods Twenty-four-hour Holter ECGs were analyzed in 66 normal subjects during placebo and moxifloxacin delivery ... -
Influence de la perception de soi sur la motivation autonome et les actes de revendication de leader
(2023-08)Le développement du leadership est un phénomène complexe s’opérant à travers toute la vie. Le début de l’âge adulte est une période particulièrement charnière, puisque les nouvelles activités dans lesquelles les jeunes s’engagent seront intégrées dans ... -
An eikonal-diffusion solver and its application to the interpolation and the simulation of reentrant cardiac activations
(Elsevier, 2012)Electrical propagation of the cardiac impulse in the myocardium can be described by the eikonal-diffusion equation. This equation governs the field of activation times in a domain where conduction properties are specified. This approach has been applied ... -
Fitting local repolarization parameters in cardiac reaction-diffusion models in the presence of electrotonic coupling
(Elsevier, 2017)Background: Repolarization gradients contribute to arrhythmogenicity. In reaction–diffusion models of cardiac tissue, heterogeneities in action potential duration (APD) can be created by locally modifying an intrinsic membrane kinetics parameter. ...
