Ahhh.. The halter moniter right? Usually your cardiologist wont see anything using a halter moniter unless this is a day to day thing. I would ask him to get a tilt table test scheduled. That will show him/her exactly what is going on instantly if it has to do with the heart. I hope that you get this one figured out soon. Oh, and remember you are 'your own' best doctor. You know what you feel inside and the doctors work for you. Do some research and 'tell' them what you want to do. They will usually listen. Good luck my friend.
