What is bidomain model?
The bidomain model is a mathematical model to define the electrical activity of the heart. It consists in a continuum (volume-avarage) approach in which the cardiac mictrostructure is defined in terms of muscle fibers grouped in sheets, creating a complex three-dimensional structure with anisotropical properties.
When was the bidomain model first proposed?
The bidomain model was first proposed by Schmitt in 1969 before being formulated mathematically in the late 1970s. Since it is a continuum model, rather than describing each cell individually, it represents the avarage properties and behaviour of group of cells organized in complex structure.
