Based on prior knowledge, we can analyze the relationship between the feature "n_p_ecg_p_06" (Third-degree AV block on ECG at the time of admission to the hospital) and the presence of chronic heart failure in a patient.

Analysis:
1. If the value of "n_p_ecg_p_06" is 'no', it indicates that the patient did not have a Third-degree AV block on ECG at the time of admission to the hospital.
2. If the value of "n_p_ecg_p_06" is 'yes', it indicates that the patient had a Third-degree AV block on ECG at the time of admission to the hospital.

Based on this analysis, we can create a dictionary with the desired format:

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

In this case, there are no additional values for the feature "n_p_ecg_p_06" that are hard to predict or not included in this analysis.
