Development of a linear transient model for stimulation of isolated cardiac cells

Isolated cardiac cells stimulators design can be aided by numerical tools based on the behavior model. The linear model (RC circuit) is the most straightforward model for describing the electrical membrane cell behavior for an external electrical stimulation: however, an adjustment is necessary to make it competent to describe correctly the different types of excitation variability experimentally observed. A Linear Transient Model is presented, solved by the Finite Element Method.
