Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms could be related to cardiac arrhythmia. Anxiety could also mimic this clinical situation. I recommend consulting with your doctor for a careful physical examination and some tests: - a resting ECG and a cardiac ultrasound to examine your heart structure and function- an ambulatory 24-48 hours ECG monitoring to examine your heart rhythm trends during the day-lab blood tests complete blood count, thyroid hormone levels, blood electrolytes. I recommend discussing with your doctor on the above issues. Hope to have been helpful! Best wishes,
