title: Parametric sensibility study of the sinoatrial node math model.
abstract: The results of the parametric sensibility study to the sinoatrial node math model was presented. The model was proposed by H. Zhang, A. V. Holden and M.R. Boyett. The sensitivity analysis indicates that the sodium and potassium ionic concentrations need to be controlled in order to maintain the normal behavior of the node. The calcium concentrations changes simulated don't produce significant effects over the operation of the node. One response surface model was developed as a simplification of original model. The diastolic depolarization rate was redefined in order to allow its measure in potential waves for peripheral node cells.
