Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes,
anxiety can be the cause for all these but better to rule out
arrhythmia (rhythm disturbances in heart) first.
Arrhythmia can cause irregular heart beats, skipped beats, palpitations etc. If not treated promptly, arrhythmia can be life threatening and fatal.
So 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.
Anxiety can be the cause.
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.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
