Effects of altering PCa on spiral-wave meandering. The evolution of the
tip-trajectory is shown for 120 ms (a) and 600 ms (b). For the standard configuration
(a.iv),(b.iv) PCa = 0.25 nA/mM while for the other plots:
(a.i),(b.i)
PCa= 0.1 nA/mM,
(a.ii),(b.ii)
PCa
= 0.125 nA/mM, (a.iii),(b.iii) PCa= 0.1875 nA/mM,
(a.v),(b.v)
PCa= 0.3 nA/mM,
(a.vi),(b.vi)
PCa
= 0.35 nA/mM. In plot (c) the corresponding restitution curves are shown. The horizontal solid
bar in (a) and (b) is 1 mm long. The simulations were run in a
20 mm×20 mm homogenous medium
in which a counter-clockwise rotating spiral was initiated.
