Based on prior knowledge, we can analyze the relationship between the feature "nr_08" (Ventricular paroxysmal tachycardia in the anamnesis) and the presence of chronic heart failure in the patient.

It is logical to assume that the presence of Ventricular paroxysmal tachycardia in the anamnesis might indicate a higher likelihood of chronic heart failure in the patient. Therefore, we expect that patients who have experienced Ventricular paroxysmal tachycardia in the anamnesis would show chronic heart failure (target class "yes").

To create the requested dictionary, we need to identify the possible values of the feature "nr_08" for each target class.

By examining the data, we can populate the dictionary as follows:

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

Since the feature "nr_08" is a categorical variable with only two possible categories ('no' and 'yes'), we include both values in the dictionary for the respective target classes.
