[Bug] [cardiac_pm.py](http://_vscodecontentref_/65) imports pulsatile_model_functions and healthy_params which don't exist in the repo

[GaneshPatil7517]

In cardiac_pm.py:2-3:

import pulsatile_model_functions as pmf
import healthy_params as K

Neither pulsatile_model_functions.py nor healthy_params.py exist anywhere in the repository. Running this tool will immediately crash with ModuleNotFoundError. These modules should either be:

1. Added to the repository, or
2. Listed as external dependencies in requirements.txt with installation instructions, or
3. The file should document where to obtain them
