Cathy...I get those all the time. I once had them everyday for two years, and we're talkin' a skipped beat every four of five seconds. All Ekg's etc, were normal. They looked for that Prolapse-thing...Nope. I was told every person over forty gets them but don't notice them because they don't have anxiety/fibro, which I do. Sometimes I don't feel them all day long, then sit down to rest and they start in like gang busters. It is annoying, but not dangerous. My son gets them also and he has anxiety disorder.
I know it's not easy to just forget about them, but I'm sure you're fine.
