Further cardiac tests recommended...
I have read your medical history and what you feel as extra heart beat might be extra-systoles.
I suggest to do :
- Holter monitoring
- cardiac echo
to evaluate the heart condition. If everything is ok, then, there is nothing to be worried about.
I also advise :
- not to drink coffee, carbonated drinks, energetic drinks
- have regular meals, do not skip
- avoid alcohol
- avoid oily/spicy, chilly foods
Hope it was of help!
