thanks for ur query
first of all sir please dont be so much conscious for that problem
it may be due to your panic attack
for which you can take alprazolam tablets 0.5 mg daily at bed time and look for the improvement over two weeks. Along with this you need to have a psychiatric counselling
to releive your anxiety level.
you may have a TMT for that to make sure that its not your heart to cause problem along with serum CPK-MB assay and serum troponin
T assay. If both the tests came negative you need not to worry then. Again you also may go for serum BNP assay to exclude your heart failure
Dont be panicked dear because it will cause more problem. Try to be relaxed. You may also try meditation
to releive your anxiety.
