Assessment of a Threshold Method for Computing Activation Maps from Reconstructed Transmembrane Voltages
Emma Lagracie, Lisl Weynans, Yves Coudière
Electrocardiographic imaging non-invasively reconstructs activation maps of the heart from temporal body surface potential maps by post-processing solutions of an inverse problem.…
Comparison of Two Formulations for Computing Body Surface Potential Maps
Emma Lagracie, Lisl Weynans, Yves Coudière
In order to establish a link between the activation map and the body surface signals, we want to compute body potentials from activation maps and a frontlike approximation of the a…
Monte Carlo guided Diffusion for Bayesian linear inverse problems
Gabriel Cardoso, Yazid Janati El Idrissi, Sylvain Le Corff +1
Ill-posed linear inverse problems arise frequently in various applications, from computational photography to medical imaging. A recent line of research exploits Bayesian inference…
Microscopic Tridomain Model of Electrical Activity in the Heart with Dynamical Gap Junctions. Part 1 -- Modeling and Well-Posedness
Fakhrielddine Bader, Mostafa Bendahmane, Mazen Saad +1
We present a novel microscopic tridomain model describing the electrical activity in cardiac tissue with dynamical gap junctions. The microscopic tridomain system consists of three…
Three Scale Unfolding Homogenization Method Applied to Cardiac Bidomain Model
Fakhrielddine Bader, Mostafa Bendahmane, Mazen Saad +1
In this paper, we are dealing with a rigorous homogenization result at two different levels for the bidomain model of cardiac electro-physiology. The first level associated with th…
Reducing Line-of-block Artifacts in Cardiac Activation Maps Estimated Using ECG Imaging: A Comparison of Source Models and Estimation Methods
Steffen Schuler, Matthias Schaufelberger, Laura R. Bear +9
Objective: To investigate cardiac activation maps estimated using electrocardiographic imaging and to find methods reducing line-of-block (LoB) artifacts, while preserving real LoB…
Impulse data models for the inverse problem of electrocardiography
Tommy Peng, Avinash Malik, Laura R. Bear +1
The proposed method re-frames traditional inverse problems of electrocardiography into regression problems, constraining the solution space by decomposing signals with multidimensi…
A computationally efficient physiologically comprehensive 3D-0D closed-loop model of the heart and circulation
Christoph M. Augustin, Matthias A. F. Gsell, Elias Karabelas +5
Computer models of cardiac electro-mechanics (EM) show promise as an effective means for quantitative analysis of clinical data and, potentially, for predicting therapeutic respons…
Automatically Segmenting the Left Atrium from Cardiac Images Using Successive 3D U-Nets and a Contour Loss
Shuman Jia, Antoine Despinasse, Zihao Wang +5
Radiological imaging offers effective measurement of anatomy, which is useful in disease diagnosis and assessment. Previous study has shown that the left atrial wall remodeling can…
Scale-Invariant Structures of Spiral Waves
Daniel Sohn, Konstantinos N. Aronis, Hiroshi Ashikaga
Spiral waves are considered to be one of the potential mechanisms that maintains complex arrhythmias such as atrial and ventricular fibrillation. The aim of the present study was t…
Is Human Atrial Fibrillation Stochastic or Deterministic?
Konstantinos N. Aronis, Ronald D. Berger, Hugh Calkins +6
Atrial fibrillation (AF) is the most common cardiac arrhythmia in human beings, and is associated with significant morbidity and mortality. The current standard of care includes in…
Efficient high order schemes for stiff ODEs in cardiac electrophysiology
Charlie Douanla Lontsi, Yves Coudière, Charles Pierre
In this work we analyze the resort to high order exponential solvers for stiff ODEs in the context of cardiac electrophysiology modeling. The exponential Adams-Bashforth and the Ru…
Causal Unit of Rotors in a Cardiac System
Hiroshi Ashikaga, Francisco Prieto-Castrillo, Mari Kawakatsu +1
The heart exhibits complex systems behaviors during atrial fibrillation (AF), where the macroscopic collective behavior of the heart causes the microscopic behavior. However, the r…
Inter-Scale Information Flow as a Surrogate for Downward Causation That Maintains Spiral Waves
Hiroshi Ashikaga, Ryan G. James
The mechanism that maintains atrial fibrillation (AF) remains elusive. One approach to understanding and controlling the mechanism ("AF driver") is to quantify inter-scale informat…
Nonlinear trend removal should be carefully performed in heart rate variability analysis
Binbin Xu, Rémi Dubois, Oriol Pont +1
Background : In Heart rate variability analysis, the rate-rate time series suffer often from aperiodic non-stationarity, presence of ectopic beats etc. It would be hard t…
Towards the selection of patients requiring ICD implantation by automatic classification from Holter monitoring indices
Charles-Henri Cappelaere, R. Dubois, P. Roussel +1
The purpose of this study is to optimize the selection of prophylactic cardioverter defibrillator implantation candidates. Currently, the main criterion for implantation is a low L…
