Hello!
Thank you for asking on HCM! Regarding your concern, I would explain that as long as your heart rhythm is always normally
sinus rhythm, there is no place to get panic.
Relax and don't worry!
Sinus tachycardia is a normal physiological reaction against different exogenous or endogenous stimuli.
You need to perform a medical check up by your doctor (GP or internist) for a physical examination and some additional tests tests (ECG,
complete blood count to rule out anemia or inflammation, PCR,
thyroid hormone levels for any dysfunctions, fasting glucose, liver and renal function tests, blood electrolytes,
arterial blood gas analysis, etc), to identify the right cause of your tachycardia.
If everything results normal, then a psychological status evaluation is necessary to rule out any symptomatology of anxiety, which may be responsible for tachycardia.
Hope to have been helpful! Greetings! Dr. Iliri
