Anyway, before coming to this conclusion, I would recommend consulting with your attending physician for a physical exam and some tests in order to exclude other possible causes: - a resting ECG and cardiac ultrasound-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance-complete blood count for anemia. An ambulatory 24-48 hours ECG monitoring would help exclude possible cardiac arrhythmia. You should discuss with your doctor on the above tests. Hope I have answered your query. Let me know if I can assist you further.
