Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, by your history and description, possibility of heart related diseases like
heart failure or
arrhythmia (rhythm disturbances in heart).
So better to
consult cardiologist and get done
1. Blood pressure monitoring
2. Ecg
3. 2d echo
4. Holter monitoring (24 hours continuous recording of ecg).
If all these are normal then no need to worry for heart diseases.
Sometimes, uncontrolled 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 it's solution.
You may need anxiolytic drugs too. Don't worry, you will be alright. 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.
