<p><b>A:</b> APD adaptation after a sustained change in rate from normal to fast pacing (750 to 400 ms), for different slow APD adaptation time constants. <b>B:</b> S<sub>1</sub>–S<sub>2</sub> APD restitution at different S<sub>1</sub> cycle lengths. Aggregated experimental restitution data at a CL = 500 ms is shown for comparison. Inset shows steady-state APs at the indicated CLs.</p
