Based on my prior knowledge, the feature "ritm_ecg_p_01" represents the ECG rhythm at the time of admission to the hospital. The feature has two categories: "yes" and "no", indicating whether the patient has a sinus rhythm with a heart rate between 60-90 or not.

To analyze the relationship between this feature and the task of determining chronic heart failure, we need to consider if there is any known connection between ECG rhythm and chronic heart failure. If research or medical literature suggests that patients with a specific ECG rhythm (such as sinus rhythm) are more likely to have chronic heart failure, then it would indicate a relationship between this feature and the target. However, without further information, we cannot make any definitive conclusions about this relationship.

Nevertheless, we can create the requested dictionary based on the available information:

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

Since the categories for the "ritm_ecg_p_01" feature are "yes" and "no", we simply list both of them for each target class to ensure that the lists are not empty.
