After analyzing the relationship between the feature `ritm_ecg_p_01` and the task of determining if the patient has chronic heart failure, it appears that the ECG rhythm at the time of admission to the hospital does not directly indicate the presence or absence of chronic heart failure. Therefore, we cannot definitively determine if the patient has chronic heart failure based solely on the value of `ritm_ecg_p_01`.

However, to create the requested dictionary, we can still provide the possible values of `ritm_ecg_p_01` for each target class:

```json
{
	"no": ["yes", "no"],
	"yes": ["yes", "no"]
}
```

Since the feature `ritm_ecg_p_01` does not provide meaningful insight into the presence of chronic heart failure, the lists for both target classes contain all possible values of `ritm_ecg_p_01` ("yes" and "no").
