Donna, if you've had your EKG and they let you go home the news is usually good.
IF there was a problem, the EKG tech would have recognized it, contacted your dr and they'd have rushed the other tests or admitted you for observation. While a tech isn't allowed to give you the results, they usually know how to read them and will alert the dr if there's a major concern.
So I'm thinking you passed this part at least!
Keep us posted hon. We'll keep praying for you.
