Short PR Interval
Anon_58874 posted:
I've been doing an ECG recently and I've been told that my PR was out of range at 105 for my age (male, mid-30s). Supposedly, it should be between 120-200. I did a repeat of the test and my PR was under 100. I was worried about the result and did consult a physician in Canada. The physician (as most Canadian physicians) was rude and told me that I had nothing to worry about because ECGs are always changing, giving random numbers.

I have been checking on Google and have seen many conditions associated with short PR intervals. Should I see a doctor in the US? I am very worried about my health.

Yes, of course, or at least for now, consult with another doctor if your still in Canada, even it it turns out being a so-called "normal variant".

Best of luck down the road of life. Live long and prosper.

Take care,

Shortened PR Interval

Short PR Interval on ECG
_ . _

A short PR interval may be associated with an otherwise normal electrocardiogram or a myriad of bizarre electrocardiographic abnormalities. Clinically, the individual may be asymptomatic or experience a variety of complex arrhythmias, which may be disabling, though rarely cause sudden cardiac death.

James Beckerman, MD, FACC responded:
It's true that there are some heart rhythm disturbances associated with a short PR interval - such as Wolff Parkinson White syndrome or Lown Ganong Levine syndrome - both involve electrical bypass tracts that could increase the likelihood of abnormally fast heart rhythms. In people who have no history of any symptoms of palpitations or fast heart rates, cardiologists tend not to put them through invasive evaluations or much further testing. Best to discuss your own situation with your doctor - if you are not crazy about your relationship with your current doctor you could always get a second opinion.
sahasrangshu responded:

You could be having a WPW syndrome or an LGL syndrome.These cases could often lead to palpitation leading to PSVT or atrial fibrillation.Do not be upset as currently there is no medication to alter your PR interval but yes you should consult a cardiologist and get the correct diagnosis done.I hope a suitable cardiologist will sort out the problems that you have and you could live a better life.
