Based on my prior knowledge, I will analyze the relationship between the feature "n_p_ecg_p_11" (Incomplete RBBB on ECG at the time of admission to hospital) and the task of determining whether the patient shows chronic heart failure.

To analyze this relationship, we can compare the values of the feature "n_p_ecg_p_11" for patients who do and do not show chronic heart failure.

Here is the analysis based on the available information:

For patients who do not show chronic heart failure (target class "no"), the possible values of the feature "n_p_ecg_p_11" could be:
- "no"

For patients who show chronic heart failure (target class "yes"), the possible values of the feature "n_p_ecg_p_11" could be:
- "yes"

Based on this analysis, I will create the dictionary:

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