The inverse problem of electrocardiography: industrial solutions and simulations
A common concern in solving the inverse problem of electrocardiography is how to efficiently assess the accuracy of the reconstruction algorithms under a wide variety of clinically relevant conditions. This paper describes a research testbed based on the SCIRun/ BioPSE computational steering software that allows rapid prototyping and evaluation of potential new algorithm improvements, as well ...
متن کاملSimulation Steering with SCIRun in a Distributed Environment
Building systems that alter program behavior during execution based on user-speciied criteria (computational steering systems) has been a recent research topic, particularly among the high-performance computing community 1{5]. To enable a computational steering system with powerful visualization capabilities to run in a distributed computational environment, a distributed infrastructure (or run...
متن کاملFinite Element Discretization Strategies for the Inverse Electrocardiographic (ECG) Problem
Successful employment of numerical techniques for the forward and inverse electrocardiographic (ECG) problems requires the ability to both quantify and minimize approximation errors introduced as part of the discretization process. Conventional finite element discretization and refinement strategies effective for the forward problem may become inappropriate for the inverse problem because of it...
متن کاملForward and Inverse Solutions of Electrocardiography Problem Using an Adaptive BEM Method
The construction of geometry models of heart-torso is critical for solving the forward and inverse problems of magnetoand electro-cardiography (MCG/ECG). Boundary element method (BEM) is a commonly used numerical approach for the solution of these problems and it requires the modeling of interfaces between various tissue regions. In this study, a new BEM (h-adaptive type) has been applied to th...
متن کاملEffects of cardiac anisotropy on three-dimensional ECG localization inverse solutions: a model study
The aim of the present study was to examine the effect of cardiac anisotropy on the ECG inverse localization solutions using a heart-model-based approach. The anisotropic heart model was used in forward pacing simulation while anisotropic and isotropic heart models were used in inverse procedures, respectively. Twenty-four sites throughout the ventricles were paced and the sites of origins of v...
