Thanks all for the very informative (and sobering) responses on this. I think I probably had already guessed the basic answer that I need to get it thoroughly checked out before doing any more diving. I'll get the standard stuff checked out first and once everything settles down start looking for a specialist diving doc.

They ruled out a number of likely causes with blood tests and lifestyle questions (And yes I was honest !) so they will carry out further investigations over the coming weeks.

Saw my own doc yesterday and she mentioned that the real concern would have been the additional 'VT / SVT with abberancy' . (Whatever that is !!!!)

Oh well, anybody want to buy some dive kit ??

Thanks again for all the advice.
