Short pr syndrome.
I ama 52 year old women with Cornary artery disease, Pulmonary Hypertension, Diabetes and FMD of my renal arteries. Two weeks ago I had an mildly abnormal EKG done at pre op for angioplasty for renal arteries. It showed Short PR syndrome and I was boderline. A few days later my ekg was back to normal. From what I understand Short PR has something to do with the beat of the heart being to short. I am currently wearing 30 day monitor of heart. Since that abnormal reading I have been fine so my question is is Short PR just something that comes and goes? If so what things can be done to prevent from happening again? Thanks
Before the doctor answers, I just wanted to explain what short PR is.
I will assume you mean short PR, not short QT, because I have never heard of "short PR syndrome" (it's usually named WPW or LGL syndrome) but there is a "short QT syndrome" and from what you say, the beat of your heart being too short, that's a more correct description of short QT. Anyway, back to short PR:
The PR time is the time between activation of upper and lower heart chambers (atria and ventricles). Conduction between the chambers are delayed so the atria may contract (and fill up the ventricles) before the ventricles contract, so the heart can pump efficiently.
Between the upper and lower chambers, you have the so-called AV node, which delays the impulse slightly.
Some people are born with extra pathways connecting atria and ventricles. This extra pathway isn't programmed with any delay, so ventricular activation through this pathway happens before it's supposed to. This is visible on EKG as short PR time, along with a slow activation of one of the ventricles (the one the extra pathway is connected to). This condition is named WPW syndrome (Wolff-Parkinson-White)
In rare cases, the extra pathway runs between the atria and the normal ventricular conduction system, the result is a short PR time but normal ventricular activation. This is named LGL syndrome (Lown-Ganong-Levine).
Short PR isn't necessarily caused by an extra pathway. It can happen with higher heart rate, and in general, adrenaline and similar substances will make the AV node conduct faster. The PR time will vary.
This was just an explaination and not a diagnosis. The doctor can help you with your specific case.
Good luck!

I don't know. The cardiologists here usually don't read members replies so I don't think that's the reason.
My best advice is to ask your physician what condition he thinks causes the short PR, if there is any (you say this comes and goes). It's a bit confusing how physicians sometimes tend to tell you about random EKG findings without explaining why they appear.

Apparently my question is not going to be answered. The other question from yesterday was. Is it because someone responded before the Doctor did and thus the Doctor did not think my question was new or was it that Doctor thought it was a dumb question. It was not to me because I am confused by this. Oh well quess I will need to look somewhere else to hopefully find the answers.
Short PR syndrome was what was written on the EKG my Doctor said that it showed Short PR Interval. I do not understand much about it other then it deals with the beat of heart being too short. Thanks for responding and writing an explaination.
