Thanks for your question on Healthcare Magic.
I can understand your concern.
Most common cause for palpitations is stress and
anxiety.
But better to rule out
arrhythmia (rhythm disturbances in heart) because this can also cause palpitations in young individuals.
And if not treated promptly, arrhythmia can be life threatening.
So
consult doctor and get done ecg, 2d echo 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 and uncontrolled stress can also cause palpitations.
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. But first rule out arrhythmia.
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.
