question: i have palpatations mainley assocciated with my sleep. I have been going to a cardioligist for years, and have had many tests done to no avail. I have worn a 24 Hr halter 2 times with no results I had a spontanious lung collapse 15 years ago followed by a thoracotomy at the time to repair the damage When i am awoken by these palpitations and feel my heartbeat it is normal or perhaps slightly elevated and completley out of rythm with the palpatations . MY cardioligist has been trying for some time to figure these palpatations out Does anybody have any feeling about this Thankyou
