You mentioned that your heart rate
is high even in normal condition and at rest. Normally the resting heart rate should be between 60 - 100.
Also you said you have cough.
You will need to undergo following investigations.
- People with low or borderline Hb have increased heart rate
2. TSH for evaluation of thyroid
3. Chest X ray
for evaluation of your Cough
This will give a clear picture of what we are dealing with.
Hope this answers your query.
Thanks and Regards
