Based on prior knowledge, the RestingECG feature is related to the presence of heart disease. Here's the analysis of the relationship between the RestingECG feature and the task:

- Normal RestingECG: A normal resting electrocardiogram result indicates a low probability of heart disease. 
- ST RestingECG: An ST elevation on the electrocardiogram can be an indication of myocardial infarction or heart ischemia, which are associated with heart disease.
- LVH RestingECG: LVH stands for left ventricular hypertrophy, which is an enlargement and thickening of the heart's main pumping chamber. LVH is often caused by underlying heart conditions and is associated with an increased risk of heart disease.

Based on this analysis, we can create the required dictionary:

```json
{
	"no": ["Normal"],
	"yes": ["ST", "LVH"]
}
```
