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

To determine this relationship, we need data samples that contain both the feature and the target information. By comparing the feature values for each target class, we can understand how they are related.

Here is the analysis of the relationship between the feature "nr_08" and the presence of chronic heart failure:

- If the value of "nr_08" is "no":
    - There is a possibility of chronic heart failure
    - Other feature values may have a greater influence on the presence or absence of chronic heart failure

- If the value of "nr_08" is "yes":
    - There is a possibility of chronic heart failure
    - Other feature values may have a greater influence on the presence or absence of chronic heart failure

Based on this analysis, we can create the following dictionary:

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

Please note that this dictionary only includes the exact values found in the dataset for each target class. If there are other values for the feature "nr_08" that are hard to predict or not included in the dataset, they are not necessary to include in the dictionary.
