I have always had a short PR interval on my tests too. No doctor has ever commented on it so I didn't think much of it until recently. I went for a sleep study and they saw it and were concerned. They want me to have a 12 lead Electrocardiogram to see if it is a problem or not. My guess is that the techs on my older tests didn't see any delta waves so they thought it was a normal variant but my sleep test showed delta waves so its possible I could have WPW. I am seeing a cardiologist in November but have a Echocardiogram and electrocardiogram next month. I've seen the cardiologist on and off for years because I have Mitral valve prolapse and symptoms that I now know are from POTS. I would say that if he didn't catch WPW by now than I probably don't have it HOWEVER he missed the POTS diagnosis all this time and it was so obvious... . Best to just get it checked out. I have no idea about my calcium and potassium levels though...need to check those out too. 8 ) good luck!
