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

Help downloading and running models
Detailed Markov models of IKs (the slow delayed rectifier K+ current) and its alpha-subunit KCNQ1 were developed. 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 paper for more and details.
