Influence of dimensionality on the distribution of depolarization and repolarization times and APD on a one-dimensional cable 2 cm long (solid), along a diameter of a two-dimensional circle 2 cm in diameter (dashed), and along a diameter of a three-dimensional sphere 2 cm in diameter (dash-dots). Although the APDs at the boundaries are nearly the same, the APD at the stimulus site increases with dimensionality because of electrotonic effects that increasingly delay repolarization as the dimension increases.
