I always see the letters Dx as the abbreviation of diagnosis, but I never understand how does this letter relate to the word diagnosis which doesn't contain the letter x. Therefore my question is
What do these two letters (Dx) stand for?
An example using these letters:
Dx: atrial fibrilation and right bundlebranch block. (in cardiology)

There are a number of abbreviations which use the first letter and an 'x'. The other ones I can think of are:
Rx - Latin recipe ("take" - the traditional first word of a recipe!)
Tx - transmit/transmission
Rx - receive/reception
I suspect that the practice goes back to scribal abbreviations, though I don't know for sure.
