22 year old female with fast resting heart rate

[susanhutt]

My daughter's trainer has told her she must be cleared by a physician before she can workout at the gym.  She has been working out regularly (3-5 days a week for the past 5 years).  Her resting heart rate is 105.  On a recent stress test her rate reached 205 after only 13 minutes and 40 seconds -- the incline and speed were gradually increased.  Her resting blood pressure was 90 over 60 and was 120 over 70 at the end of the test.  She said her doctor didn't believe her when she first told him how the rate would increase with exercise.  After the stress test he suggested that maybe she has a thyroid problem.  My daughter had to remind him that he had already done blood work and told her there wasn't a thyroid problem.  He dismissed this and told her that he didn't have her chart in his possession at the moment.  Obviously she needs to see another doctor.  Anyone have experience with these symptoms?  Any suggestions?

I actually have a resting hr of 106 and during exercise it hits 190-200. I have also been tested for thyroid issues and heart conditions. I am only 23 and at a reasonable weight of 145 pounds and I am 5'8. I have seen numerous specialists who have done nothing for me, and found no answers. I would be interested to hear what others have to say...
