[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I read your question carefully and understand your concern. I would like to explain that in your situation, a careful differential diagnosis between a metabolic disorder (like chronic anemia, thyroid or a Chat Doctor.  What are the values of your blood pressure? I recommend consulting with your GP for a careful physical exam, a resting ECG, a chest x-ray and some blood lab tests : - complete blood count- PCR, sedimentation rate (chronic inflammation)- kidney and liver function tests-blood electrolytes- fasting glucose-thyroid hormone levels-cortisol plasma levels, etc. An ambulatory 24-48 hours ECG monitoring and a cardiac ultrasound are necessary to examine your cardiac function and rule in/out any possible cardiac arrhythmia. If all the above tests result normal, and your heart rhythm is above the normal levels, you should discuss with your attending physician the possibility of starting a beta blocker (atenolol, nebivolol, etc.). Hope to have been helpful! Best regards,
