Is there a way to see what fields are used in Rules?

There is an field list overview in the reports for Views that shows the fields used. Is there a quick way to find out which fields are used with Rules? It would be enough to check if a certain field is used by Rules

SOLUTION:

As I don't have a special SQL tool drush works too by entering Pierre's query:

drush sqlq "SELECT id,plugin,active,name,label FROM rules_config WHERE data LIKE '%points_dec%'"

enter image description here.
