T_peak is described in MAT_295

Parameters:

t_endint, default: 800

Heart beat period.

t_actint, default: 0

Start time.

Returns:

tuple[np.ndarray, np.ndarray]

(time, stress) array

curve.constant_ca2(tb: float = 800, ca2ionm: float = 4.35) → tuple[numpy.ndarray, numpy.ndarray]

Constant ca2 curve for Active model 1.

Parameters:

tbfloat, default: 800

Heart beat period.

ca2ionmfloat, default: 4.35
