Thanks for your question on Healthcare Magic.
I can understand your concern.
Fluttering sensations in chest are mostly due to
arrhythmia (rhythm disturbances in heart).
If untreated, arrhythmia can be life threatening.
So we should first rule out arrhythmia in your case.
So
consult cardiologist and get done
1. Ecg
2. 2d echo
3. Holter monitoring (24 hours continuous recording of ecg).
You may need anti arrhythmia drug on the basis of these reports.
If these reports are normal then no need to worry for arrhythmia or other serious heart diseases.
Sometimes,
stress and
anxiety can also cause Fluttering sensations in chest.
So avoid stress and tension, be relax and calm.
Don't worry, you will be alright but first rule out arrhythmia.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
