**Exploring Multistable Reentry Patterns**

*The parameter values*:

__APD__:

__CT__:

*APD and CT restitution functions (t = DI)*:

*Initial DI values (x = DI)*:

****All initial DI = 50 in this case****

*Equations and iteration commands*:

"N" is the number of iterations

*Tracking the cycle length (CL) and APD*:

R = CL:

**Periodic oscillation pattern**

**is observed in this case**

Beat: 4998 4999

CL: 235.5 232.6

APD: 230.8 121.5
