Thank you for your helpfull comments. Although there is nothing I can do about it while my body is good enough to behave 'healthily', I will be sure to remember to ask for the tests you mentioned if I ever have another episode. I will also not try to be brave and visit the GP the next day - I will phone emergency services there and then!!
It is quite tiresome to be told "it can't be your heart, therefore it must be your head"... your comment about coagulation and dehydration was something new, and when you're been bounced about with the same old same old... something new is always good :)
Actually it sounds very simple and logical, and I have changed my daily routines to include more movement and liquids - maybe this will prevent any more unpleasent episodes. Thanks again.
Thanks for your advice. Although I agree with you re specialists, I need a referral from a GP (UK National Health System!), so it's back to - how hard to I argue when they tell me there's nothing wrong :( (going private is not an option on my salary)
I can't comment on your numbers but would suggest going to an EP (electrophysiologist) who specialize in heart rhythm issues for further evaluation. A specialist may have better answers than you GP.

What you need is both an MRI and a dye-contrast MRA. I would also like you to have an EEG (of the brain waves).
I am concerned about the juxtaposition of the "metallic taste", which is common with those who experience seizures. This leads me to expect a neurological event. The combination of chest and leg pains is unusual.
The "struggling to breathe" could have several causes, including a momentary blockage of a main blood vessel leading to the lungs by a clot. This would reduce circulation causing pain in the legs. You need to have a ptt (blood clotting test). The primary cause of this problem is dehydration and inactivity.
My gut feeling is this may be a side effect of a medication, but I admit that's a long shot. Look up all your meds in the PDR.
Your EKG results are acceptable, however, in case your physician did not inform you an ordinary EKG (or ECG) is worthless. You require a stress EKG to obtain any meaningful data on a potential developing infarct. Your readings are not exactly what I would like to see, but consistent with a physician telling you "not to worry".
It seems as if your physician treats you like a mushroom. Keeping you in the dark and feeding you you-know-what.
