This model has been curated by Penny Noble of Oxford University and is known to run in PCEnv and COR and reproduce the results published in the paper it is based on.

Model Structure

In 1984 D. Noble and S.J. Noble published a mathematical model which describes electrical activity in the sino-atrial node. Their model is based on the Purkinje fibre model developed by D. DiFrancesco and D. Noble (please see the CellML version of the DiFrancesco-Noble Purkinje Fibre Model, 1985). Most of the equations of this cardiac cell model remain unchanged. However, based on the results of experimental work, where necessary, certain parameters have been modified in order to make the model appropriate to a sino-atrial node.
