[|Human|] I felt like I was going to faint yesterday, followed by rapid heart rate.  The heart rate would not go down. We went to the ER and the took blood sample and said my troponin was .05, took it again and it was .06. They kept me in the hospital overnight and did two more blood tests 6 hrs apart. They said it had gone down, but I needed to see my regular doctor for a strees test. Did I have damage to my heart, they said this morning that I didnt have a heart attack.  I am confused about the Triponin levels and that they are released when you have damage to your heart? Thanks......
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms could be related to a cardiac arrhythmia. In my opinion, considering your Troponin levels, I would exclude any myocardial ischemia. But, I would agree with the doctor recommendation for an exercise cardiac stress test. I would also recommend some other tests: - a cardiac ultrasound- an ambulatory 24-48 hours ECG monitoring to investigate for cardiac arrhythmia. You should discuss with your doctor on the above issues. Hope you will find this answer helpful! Kind regards,
