Based on the given feature "n_r_ecg_p_10", which represents "Ventricular fibrillation on ECG at the time of admission to the hospital", and the task to determine if the patient shows chronic heart failure, there is insufficient information to establish a direct relationship between the feature and the target variable.

Without any other variables or additional context, it is difficult to predict whether the presence or absence of ventricular fibrillation on ECG at admission is indicative of chronic heart failure. Therefore, we cannot provide specific details on how the feature relates to the target variable based on prior knowledge alone.

Hence, the dictionary will be as follows:

```json
{
	"no": ["no"],
	"yes": ["no"]
}
```
Here, we only have one possible value for the category "no". Since there is no information available for the "yes" category, we can only include the available value (which is "no") in both lists.
