[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I read your question carefully and understand your concern. I would like to know your age and your past medical history. Are you taking any medications? It is necessary to exclude a possible cardiac arrhythmia, related to your symptomatology. I recommend consulting with your GP for a careful physical examination, a resting ECG, a cardiac ultrasound, a chest x-ray study and some blood lab tests: - complete blood count-cardiac enzymes-thyroid hormone levels (thyroid gland function)- cortisol plasma levels (a Chat Doctor.  An ambulatory 24-48 hours ECG monitoring is needed to rule in/out possible cardiac arrhythmia. If all the above tests result normal, the main cause of your symptomatology would be just anxiety. Hope to have been helpful! Feel free to ask any other questions, whenever you need! Best regards,
