A to C, APD90 restitution curves as a function of basic cycle length (BCL); D to F, APD90 restitution curves as a function of diastolic interval (DI). APD90 is the action potential duration at 90% repolarization, BCL is the basic cycle length, and DI is the diastolic interval; G to I, conduction velocity restitution curves simulated in cable mesh for endo, M-cell, and epicardium cell
