Based on my prior knowledge, the presence of a posterior myocardial infarction (post_im) can be related to the occurrence of chronic heart failure. However, it is difficult to determine the exact relationship between the categories of post_im and the likelihood of chronic heart failure without additional information or a comprehensive analysis.

To create the dictionary, I will assume that the values with a higher likelihood of chronic heart failure are 'QRS is like Qr-complex' and 'QRS is like QR-complex'. The other categories may have a lower likelihood or no association with chronic heart failure. 

Based on this analysis, the dictionary will be as follows:

```json
{
	"no": ["there is no infarct in this location", "QRS has no changes", "QRS is like QS-complex"],
	"yes": ["QRS is like Qr-complex", "QRS is like QR-complex"]
}
```

Please note that this analysis is based on limited knowledge and assumptions, and more comprehensive information would be required for a more accurate analysis.
