TL;DR: Electro properties tomography derives the patient's electric conductivity, along with the corresponding electric fields, from the spatial sensitivity distributions of the applied RF coils, which are measured via MRI, which might lead to significantly higher spatial image resolution.

TL;DR: A biophysical detailed and anatomically accurate computer model of human atria that incorporates both structural and electrophysiological heterogeneities is constructed and revealed that bundles form dominant pathways for atrial conduction.

TL;DR: A comprehensive survey of the progress made in computational modeling of the human atria during the last 10 years, from simple “peanut”-like structures to very detailed models including atrial wall and fiber direction.

TL;DR: To assess the models' ability to replicate modified properties of human myocytes and tissue in cardiac disease, electrical remodeling in chronic atrial fibrillation was chosen as test case and healthy and remodeled model variants were compared with experimental results in single-cell, 1D and 2D tissue simulations to investigate AP and restitution properties.

TL;DR: The amplitudes of both atrial and ventricular ECGs were most sensitive for blood, skeletal muscle conductivity and anisotropy as well as for heart, fat, and lungs, and the effects of conductivity uncertainties were significant.
