Short PR Interval

I'm really concerned now about my palpatations developing into a dangerous arrythmia.  I was reviewing my ekg's from awhile back and 3 out of 6 of them I have a short PR Interval. They are 112 ms, 119ms, 118ms, 122ms, 143s, 124ms.  The one with the 119ms also says High QRS Voltage and Q's in II, III, and aVF.  I was really concerned about Wolf White Parkinson's (WPW) syndrome, because of this and all the palpatations that I feel.  Could you please tell me what all this represents and if I should get this more checked out from what I've given you. Thank you so much!!! You're a life saver.  On that particular EKG is also shows "accelarated AV conduction".
Thanks again,
