The movies show a simulation of the electrical potential depolarization inside a human heart. Initially, the whole heart has a resting potential of -85mv, except for a small area in the middle which has received an electrical stimulation. This stimulation causes the tissue at that location to depolarize and affect the neighboring tissue. Subsequently, more and more tissue is depolarized, as can be seen that the isosurface of the potential spreads throughout the entire heart.
The visulization is done with VTK, in which we can see an arbitrary slice through the 3D volume, an isosurface representing value 0mv and the computational mesh on the outer surface of the heart.
