Electrical wave propagation in an anisotropic model of the left ventricle based on analytical description of cardiac architecture. [PDF]
PLoS ONE, 2014 We develop a numerical approach based on our recent analytical model of fiber structure in the left ventricle of the human heart. A special curvilinear coordinate system is proposed to analytically include realistic ventricular shape and myofiber ...
