[|Human|] I have recently found that on random occasions my heart starts pounding and I can not see stright. I feel dizzy and cant seem to get enough air. If I go outside in fresh air and take a few moments to myself it subsides but Im scared about what is going on.
[|AI|]  Hello! Welcome on Chat Doctor! I understand your concern and would explain that your symptoms seem to be related to anxiety. Anyway, I would recommend consulting with your doctor for a physical exam and some tests to exclude other possible causes that may mimic this clinical scenario: - a chest X-ray study- a resting ECG-complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes for electrolyte imbalance.  An ambulatory 24-48 hours ECG monitoring would help examine your heart rhythm trends for a prolonged time and exclude possible arrhythmia. Hope to have been helpful! Wishing all the best,
