Formation and propagation of a pulse. Formation and propagation of a pulse between successive pacing stimuli applied at the left end of the cable (v
= 0.19, v
= 0.29, and T
= 9.0 measured at x0 = 10). Solid and dashed lines show spatio-temporal dynamics of u and v, respectively. The first and last snapshots correspond to the moments when two successive pacing stimuli are applied. Time intervals between the snapshots are equal to 7.2 (20% of the pacing period).
