Thanks for your question on Health Care Magic.
I can understand your concern.
Tightness in chest with
rapid heart rate is seen in many conditions. They are not characteristics of asthma. Asthma patients usually present with cough,
wheezing and
shortness of breath.
But better to get done PFT to rule out asthma. If PFT is normal, no need to worry for asthma.
Cardiac disease like
arrhythmia can cause similar symptoms. So get done ecg and 2d echo.
If both these are normal, than no need to worry for arrhythmia or other heart diseases.
Sometimes, stress and anxiety can cause similar symptoms.
So avoid stress and tension. Be relax and calm.
Consult psychiatrist and get done counseling sessions. Don't worry, you will be alright. But first rule out asthma and heart diseases.
Hope I have solved your query.
Wish you good health. Thanks.
