jmcruz,
I do not comment on specifics of test as it is impossible to give detailed answers without having the porimary data, nor is it the purpose of this forum. If you would like a full opinion on your case, you are more than welcome to submit an elecronic consult throught the cleveland clinic website at:

You seem overly concerned with a good bill of health from your physician. I think you should reevaluate your relationship with him/her or look at yourself as his/her words of reassurance do not seem to be enough.
good luck
No offense intended but I think this same question was asked and answered about 2 days.
Trust your cardiologist , if not seek a second opinion. Good luck and try and shake your obsession with your heart it's not you doing you or your heart any good. Take care, once again don't regard this as an insult, I know anything concerning your heart puts you on edge.
Thanks for listening:-)
