Role of KCNQ1 and IKs in cardiac repolarization (Silva, Rudy 2005) (XPP)

Detailed Markov model of IKs (the slow delayed rectifier K+ current) is supplied here in XPP. The model is compared to experiment in the paper. The role of IKs in disease and drug treatments is elucidated (the prevention of excessive action potential prolongation and development of arrhythmogenic early afterdepolarizations). See also modeldb accession number 55748 code and reference for more and details. This XPP version of the model reproduces Figure 3C in the paper by default.
