Hi, thanks for your questions. It sounds like you have been really worried about HIV and have done many tests. If your HIV test at 17 weeks post exposure was negative, then this is considered to be accurate to say you do not have HIV. The symptom you describe of heart racing is not a HIV symptom and can be caused by many things such as exercise and anxiety as well as more serious conditions like thyroid problems and smoke inhalation. You might consider discussing your symptoms with a doctor who can listen to your heart and order any testing of your heart that you may need. Let us know if this does not answer your question or if you have any more questions or concerns.
