Forward Problem of Electrocardiography

The Forward Problem of Electrocardiography

The forward problem of electrocardiography involves computing the potentials and currents within the body from a known electrical potential distribution or activation sequence in the heart. This paper details an efficient computational model of the human torso for use in electrocardiographic problems. The model uses a combined finite element/boundary element method which uses bicubic Hermite ba...

Forward problem of electrocardiography: is it solved?

BACKGROUND The relationship between epicardial and body surface potentials defines the forward problem of electrocardiography. A robust formulation of the forward problem is instrumental to solving the inverse problem, in which epicardial potentials are computed from known body surface potentials. Here, the accuracy of different forward models has been evaluated experimentally. METHODS AND RE...

Forward 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...
