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) in your case because arrhythmia can cause
rapid heart rate (
tachycardia),
dizziness, breathing difficulty etc.
And if not treated promptly, arrhythmia can be life threatening.
So immediately
consult doctor 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 all these are normal then no need to worry for arrhythmia or other heart diseases.
Sometimes, uncontrolled stress and anxiety can also cause similar symptoms. 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.
