Both Pseudo ephedrine and fenoterol can affect the beat of the heart. It does not sound as if you are really allergic to the two medicines but it may be that it caused some heart side effects either in combination or due to the dosage you took. You may very well now have developed anxiety as these symptoms are very unpleasant and it feels like you are dying!
A quick way of determining if this is caused by panic and hyperventilation is to breathe slowly in and out while holding a brown paper bag over your mouth and nose - this will usually stop the attack after a minute or so if it is caused by hyperventilation.
If your asthma is out of control and you are scared to use the Berotec, ask your doctor to prescribe a short course of oral cortisone which will a) relieve the asthma and b) work as a long acting anti-allergy medication. This should not have any side effects on your heart.
Have you had lung function tests and an ECG or holter ECG as part of all the tests they did? If not I would advise you to see a physician first, and only if they find no medical cause for your symptoms, refer you to a psychiatrist.
