2008 Computers in Cardiology
Computer simulations have been used to study the mechanisms of postrepolarization refractoriness in cardiac cells under ischemic conditions at the cellular level. The ten Tusscher model of the cardiac action potential has been used with the formulation of the ATP-sensitive K + current by Ferrero et al being adopted. Cells were subjected to hyperkalemia, hypoxic and acidic conditions. The results show that the three components of ischemia decrease the action potential duration (APD) as well asdoi:10.1109/cic.2008.4749108 fatcat:oo6cnxl5yjh7lgzwyq4xabtofe
