What could be the reason for palpitations, fatigue, dizziness, and chest pain?

Hello,

Welcome to icliniq.com.

Thank you for your query. I understand your concern. Your symptoms could be related to anxiety. However, cardiac arrhythmia can not be excluded either. I suggest you consult your attending physician for a physical exam and get some tests done. Do a resting ECG (electrocardiogram) and a cardiac ultrasound, an ambulatory 24 to 48 hours ECG monitoring to investigate for possible cardiac arrhythmia, blood electrolytes, and thyroid hormone levels for thyroid gland dysfunction. If all the tests are normal, you should consider anxiety the main cause of your complaints. I hope this has helped you. Thank you.
