Dependence of spiral wave dynamics on stretch-activated currents in contracting medium.

<p>(<b>A</b>) Spiral tip trajectories are shown for different values of . Each tip trajectory illustrates drift for . Starting points and drift directions are illustrated with arrows. (<b>B</b>) Spiral wave drift velocity as function of . Drift velocity is estimated from the tip trajectories using the distance of the spiral core position. (<b>C</b>) Spiral wave period as function of . Spiral period was measured from the last spiral rotation.
