[|Human|] I am a 23 year old female. I have been experience heart pain, light headedness, and shortness of breath at different times throughout the day and night. my heart starts racing and i find it hard to breath and I feel like I am going to faint. I have been to the doctor. They took chest x-ray and blood work and cannot find anything wrong.
[|AI|]  Hello! Welcome on Chat Doctor ! Your symptoms could be related to a panic disorder. But, before coming into this conclusion, I would recommend performing some tests to investigate for other possible causes: - a cardiac rhythm Holder monitoring to investigate for possible cardiac arrhythmia- a cardiac ultrasound- a chest X-ray study and pulmonary function - blood electrolytes- thyroid hormone levels - complete blood count, sedimentation rate and PCR for inflammation. If all these tests result normal, you should consider anxiety as the main cause of your complaints. Hope you will find this answer helpful! Best wishes,
