short pr interval - update

.Hi there,
I posted a couple of weeks ago about having had an ecg done and it came back saying normal sinus rhythm with short pr interval. I have since heard from GP, and cardiologist had reviewed my ecg, and said - the p waves are normal, so doesnt indicate an av nodal/junctional rhythm(or something like that)! No mention of WPW.  Nothing else was wrong on ecg, he suggested a 24 holter monitor, and if that never showed up anything, a loop recorder.

That was it basically.  So would I be right in thinking that he never seen anything on ecg to indicate WPW?  My GP made it sound like the extra tests were to try and find a reason for the palpitations, if one.

I did mention to GP I had looked this up and was worried about WPW, and she said if had been worried about that is sure other things wouldve been done and would be moving quickly with tests etc...

Just wondered on your opinions now, I know I should really probably see all that as good news, I have just been so worried about it all.   And if its not something like WPW, what does having a short pr interval mean?

Thank you for your help .  

I am 37, female, and since hyperthyroidism/graves 7 years ago(which was treated with RAI and now on thyroxine), I have had palpitations on and off, never a big problem, and can go for months without.  Last 2 years after birth of 3rd child have had anaemia and low iron levels occasionally, and felt them worse then.  Also notice them around different times of monthly cycle.

Generally, on an ECG, short PR interval is suggestive of WPW if there is something called a "delta wave" that is making the PR interval short. It is a suggestion that there is an accessory pathway between the atrium and the ventricle, so the initial depolarization of the ventricle is via the accessory pathway (causing a slurred upstroke of the QRS complex, or a delta wave) and the rest of the depolarization of the ventricle is via the normal electrical pathway (causing the rest of the QRS to be narrow and normal).

A short PR interval by itself doesn't really mean much.

The rest of the tests sound appropriate to workup the palpitations.
