Analysis:

To determine if the patient has chronic heart failure, we need to analyze the relationship between the feature "n_p_ecg_p_06" (Third-degree AV block on ECG at the time of admission to hospital) and the target variable "myocardial infarction complications data showing chronic heart failure". 

Based on prior knowledge, a third-degree atrioventricular (AV) block is a complete block of electrical signals between the atria and ventricles of the heart. This condition leads to a significant disturbance in the normal functioning of the heart. Therefore, it is possible that patients with third-degree AV block might have an increased likelihood of having chronic heart failure.

Dictionary:

Based on the analysis, the dictionary can be created as follows:

```json
{
	"no": ["no"],  
	"yes": ["yes"]
}
```
In this case, the values of the feature "n_p_ecg_p_06" for the target class "no" is ["no"], indicating that there is no occurrence of third-degree AV block on ECG at the time of admission to hospital for patients without chronic heart failure. 

Similarly, the values of the feature "n_p_ecg_p_06" for the target class "yes" is ["yes"], suggesting that there is a presence of third-degree AV block on ECG at the time of admission to hospital for patients with chronic heart failure.
