Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should first rule out
arrhythmia (rhythm disturbances in heart) for your heart flutters.
So get done ecg, 2d echo and Holter monitoring (24 hours continuous recording of ecg).
If all these these are normal then no need to worry for arrhythmia or other heart diseases.
Sometimes, stress and
anxiety can also cause palpitations whish gives feeling of heart flutters.
So better to
consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on it's solution.
You may need anxiolytic drugs too.
Control of anxiety will also control your
acid reflux.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
