LV

class project_heart.lv.left_ventricle.LV(log_level=20, *args, **kwargs)

ejection_fraction(t_es: Optional[float] = None, t_ed: float = 0.0, **kwargs) → float

Calculates the change in volume between end-systole and end-diatole.

ES and ED are timesteps where the ES and ED occur.

Parameters

• t_es (float or None, optional) – End-systole timestep. Defaults to None.

• t_ed (float, optional) – End-diastole timestep. Defaults to 0.0.

Returns

Ejection fraction (%) at t_es. np.ndarray (n_timesteps, 1): Volumetric fraction array.

Return type

float (if t_es is specified)

xyz(**kwargs) → numpy.ndarray

Return pointer to nodal position [xyz] state array.

Raises

RuntimeError – If ‘xyz’ could not be extracted or automatically computed based on current state’s data.

Returns

Pointer to ‘xyz’ states array.

Return type

np.ndarray (n_timesteps, 3)
