A rule-based algorithm robustly models patient-specific atrial fiber orientation across different volumetric and surface meshes to enhance the understanding of proarrhythmic mechanisms.
A novel rule-based algorithm enables robust modeling of patient-specific atrial fiber orientation across various mesh structures, aiding in the understanding of proarrhythmic mechanisms.
Abstract The fiber orientation in the atria has a significant contribution to the electrophysiologic behavior of the heart and to the genesis of arrhythmia. Atrial fiber orientation has a direct effect on excitation propagation, activation patterns and the P-wave. We present a rule-based algorithm that works robustly on different volumetric meshes composed of either isotropic hexahedra or arbitrary tetrahedra as well as on 3-dimensional triangular surface meshes in patient-specific geometric models. This method fosters the understanding of general proarrhythmic mechanisms and enhances patient-specific modeling approaches.
