Medical Acronyms?

I just started working in a doctor's office as an office clerk and need to know medical acronyms that would make me faster in communicating information with my coworkers. If you know any, please list them here, or if you know a link where I can find them listed in alphabetical order (where I don't have to click each letter to get the acronyms for each letter of the alphabet...waste of time...) please list here! THANKS!!
