Pacing Site
Apex 0.77 ± 0.16 0.16 ± 0.03 113.8 ± 4.2
Mid 0.92 ± 0.30 0.27 ± 0.08 128.2 ± 8.4
Base 0.72 ± 0.20 0.10 ± 0.03 103.7 ± 4.0

Restitution properties: maximum dynamic RC slope (Sdyn, max), maximum S1-S2 RC slope (SS1-S2, max), and steady-state APD at BCL0 = 1000 ms. In the recording site section, data are included from all pacing sites; in the pacing site section, data are included from all recording sites. In the final section, data from all pacing and recording sites are included. Values are least square mean ± standard error.
