For FEM modeling, a step of a suitable mesh construction is required, which is non-trivial and time-consuming for complex geometries. A meshless method is proposed to avoid meshing. The smoothed particle hydrodynamics (SPH) method was used to solve an electrophysiological model on a left ventricle extracted from medical imaging straightforwardly, without any need of a complex mesh. The proposed method was compared against FEM in the same left-ventricular model. Both FEM and SPH methods provide similar solutions of the models in terms of depolarization times. Main differences were up to 10.9% at the apex. Finally, a pathological application of SPH is shown on the same ventricular geometry with an added scar on the heart wall.application/pdfeng© Springer The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-59448-4_32info:eu-repo/semantics/conferenceObjecthttp://dx.doi.org/10.1007/978-3-319-59448-4_32SPHMeshlessFEMCardiac electrophysiologyinfo:eu-repo/semantics/openAccess
