Analysis of electrocardiograms during atrial fibrillation
(Institute of electrical and electronics engineers, 2006-11-30)The research discussed in this article is motivated by the search for an optimal classification of the different types of atrial fibrillation (AF) on the basis of recorded atrial signals. This would facilitate the selection of an optimal therapy. This ... -
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 ... -
Evaluation of a subject-specific transfer-function-based nonlinear QT interval rate-correction method
(IOP Publishing, 2011-04-15)The QT interval in the electrocardiogram (ECG) is a measure of total duration of depolarization and repolarization. Correction for heart rate is necessary to provide a single intrinsic physiological value that can be compared between subjects and within ... -
Modeling left and right atrial contributions to the ECG : a dipole-current source approach
(Elsevier, 2015)This paper presents the mathematical formulation, the numerical validation and several illustrations of a forward-modeling approach based on dipole-current sources to compute the contribution of a part of the heart to the electrocardiogram (ECG). ...
