I think I had a silent heart attack a few days ago! What's your knowledge of this topic?

Three mornings ago I was sitting at my pic and my chest began feeling uncomfortable; it was scary. It was nothing like what happened in the movie War of the Roses; just scary and slightly painful. Then the pain moved to my lower jaw and yes; that did hurt ! And it was also in my neck. It lasted half an hour then stopped. I suppose I need an EKG. Has anyone here have experience with these symptoms?
