Restitution properties of heterogeneous sheets (A–D) and homogeneous cables (E and F). (A and B) Dynamic (S1S1) restitution curves from locations at the left edge (Δ), in the middle (•), and at the right edge (×) of a sheet (inset shows locations from which APDs are measured) without a structural barrier. (C and D) Dynamic restitution curves from locations at the left edge (Δ) and at the right edge (×) of a sheet with a structural barrier. (E and F) Dynamic restitution curves from middle of 1.5-cm homogeneous cables (inset shows locations from which APDs are measured) with 2/3 (Δ), 1/1 (•), and 4/3 (×) of the nominal maximal conductance of Ito and IKs, corresponding to the values at the left, center, and right locations in the sheets.
