<bot>: Hello, Your symptoms could be related to anxiety. Nevertheless, I would recommend performing some tests in order to exclude any possible cardiac arrhythmia or metabolic disorders: - a resting ECG and cardiac ultrasound-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance-complete blood count for anemia.  A 24-48 ECG Holder monitoring would help exclude possible cardiac arrhythmia.  If these tests result normal, you should consider anxiety as the main cause of your complaints.  Hope I have answered your query. Let me know if I can assist you further.
