Based on the feature description and the task, we want to analyze if a patient with a heart rate below 60 at the time of admission to the hospital (ritm_ecg_p_08) is likely to have chronic heart failure.

To conduct the analysis, we need to examine the relationship between the feature and the target variable (chronic heart failure). Specifically, we need to compare the values of ritm_ecg_p_08 for patients with and without chronic heart failure.

Based on prior knowledge, it is common for patients with chronic heart failure to have a heart rate below 60. Therefore, we can expect a higher likelihood of chronic heart failure (yes) if the value of ritm_ecg_p_08 is 'yes'.

Here is the generated dictionary representing the relationship between ritm_ecg_p_08 and chronic heart failure:

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

In this case, patients with chronic heart failure are more likely to have a ritm_ecg_p_08 value of 'yes', indicating sinus rhythm with a heart rate below 60 at the time of admission to the hospital.
