Thanks for your question on Healthcare Magic.
I can understand your concern.
Fluttering sensations in chest are seen with arrhythmia (rhythm disturbances in heart).
So
consult cardiologist and get done ecg, 2d echo,
stress test and Holter monitoring (24 hours continuous recording of Ecg).
If all these are normal then no need to worry for arrhythmia or other heart diseases.
Sometimes undiagnosed stress and anxiety can also cause similar symptoms.
So
consult psychiatrist and get done counselling sessions.
Try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs (
propranolol and
flunarizine combination) too.
Don't worry, you will be alright with all these.
Avoid stress and tension, be relax and calm.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
