Causes Of Pr Interval
I was told anxiety and stress can cause a short PR interval on your EKG is this true? Is it dangerous?
Short PR interval: Short PR interval < 0.12 msec is associated with Lown-Ganong -Levien syndrome and Wolf-Parkinsons-White syndrome. I would follow up with cardiologist specifically an electrophysiologist cardiologist -they know EKGs- and make sure you don't have that-because that can be treated and is significant before attributing it to anxiety. Everyone in US is anxious and stressed. ...Read more
Studies have not: Demonstrated that vyvanse (lisdexamfetamine) can cause a shortened pr interval. However, anyone may have a reaction that is unique to them or idiosyncratic. There are several conditions with short pr intervals. There are some people (mostly women) who naturally have a short pr interval. If concern seek evaluation by physician. Best regards. ...Read more
My PR interval is very short at slow heart rate (90ms) but it prolongs to 150ms at faster heart rate. What causes this??
EKG: Need to see EKG and you to figure it out. Discuss with your team. ...Read more
Can be a problem: The pr interval refers to a measurement in an ekg of how long it takes the pacemaker in the top part of the heart (the atria) to reach the bottom parts (the ventricles). The normal pacemaker is the sinus node, and it should take a certain amount of time to travel from point a to b. If too fast, a shortcut likely exists called an accessory pathway (wpw).These can cause palpitations and other symptoms. ...Read more
PR: The PR is conduction atrium to ventricle. Metabolic changes can prolong AV conduction, sometimes anatomic damage can too. PR can be shortened by accessory conduction pathways that bypass the normal anatomy that conducts the impulse atrium to ventricle. ...Read more
Fast conduction: The impulse from top of heart -sinus node originates and short circuits through a faster conduction tissues to the ventricle - short circuiting the av node or bypasses the av node- resulting on the ECG as short pr interval and some patients can get tachycardia from this, and might need specialist care - electrophysiologist. ...Read more
Time: The time it takes for a cardiac impulse to travel from the sinus node in the high right atrium through the av node in the low right atrium is measured in milliseconds by the pr interval. Accelerated conduction results in a shortened pr interval. ...Read more
My pr interval is 100ms, my qt is 586. Hb is 85 waht happened to me. No symptoms at all. Is that normal?
Short pr: The PR interval represents the time it takes for electricity to pass from the top to the bottom heart chambers. Normally, there's a delay in this passage, of up to 1/5th of a second; however, if the passage is too fast, or less than ~1/8th of a second, a short circuiting "bypass" tract may be present, which can lead to a SVT. Catheter ablation can cure these, so speak with a heart rhythm doctor. ...Read more

Few Possibilities: Sinus rhythm means that your heart is beating in a normal rhythm and pace. A short PR interval is the decreased distance between two of the waves on an EKG reading of your heartbeat. It can be caused by Wolf-Parkinson-White syndrome, a junctional rhythm, Lown-Ganong-Levine syndrome, high blood pressure, or a normal variant. Talk to your doc about these possibilities for explanations. ...Read more
My question is I have had multiple ecgs dine and some my PR interval is short and some my PR interval is normal!?!? What could be causing this?
Pre-excitation: Some patients maybe born with a bypass tract or accessory tract. An extra pathway for electricity in the heart that might make one susceptible to abnormal heart rhythms. A detailed evaluation by a cardiologist is necessary to further assess and if needed referral to an electrophysiologist. A history of palpitations, rapid heart rate or syncope may indicate the short PR is significant. ...Read more
Probably normal: A peaked t wave in v2 in an 18 year old is almost certainly normal. The pr interval of 102 ms is a bit short and qrs of 100 is a bit long - do you have wolfe-parkinson-white syndrome? ...Read more
PR Interval on EKG: Normal pr interval on an ekg is 120-200 ms., so your pr interval is short. This may be a normal variant and of no concern. However, it is also seen hypertension and various cardiac conduction abnormalities such as wolf-parkinson-white syndrome that causes an unique type of supraventricular tachycardia. Your physician should be able to tell you if your shortened pr interval is of concern. ...Read more
Slow heart rate: This describes findings on the ekg describing an slower than expected heart rate. ...Read more
Abnormal EKG.: Possible cause of a short PR interval on EKG include AV junctional rhythm, Lown-Ganong-Levine syndrome (pre-excitation with a short PR interval and a normal duration QRS interval) or Wolf-Parkinson-White syndrome (pre-excitation with a short PR interval, a long QRS interval with a delta wave often with paroxysmal tachycardia or atrial fibrillation. An electrophysiologist can help with management. ...Read more
Depends.: If the pr is really short (less than 0.12 s) or there is a delta wave could represent a ventricular pre-excitation syndrome such as wpw. Need specific numbers to answer that. Repol is often normal in your age group. ...Read more
What does it mean if ECG showed short pr interval. & flat or low neg t in avl & v6. & high lateral and lateral repoloarization disturbance (mild)?
Different things: A short pr interval means that the heart beat is either initiated in a part of the atrium which is distinct from the sinus node (where it usually starts) or is being conducted with accelerated velocity to the ventricles. The other changes are "non-specific" and can be due to anything, like sodium, potassium or magnesium levels, medicines, lead position, skeletal variation and many other things. ...Read more
I have 100atrial extrasy everyday, pr -90ms, incomplete rbbb, echo ok, stress test st/v5-1.3, st/ii-2.6 with a few extra. Is short pr interval dangerous?
Usually Not: There are two common causes of short pr, assuming you've excluded machine error (the #1 cause). 1) enhanced conduction from top to bottom. Not a problem here. 2) an "accessory pathway" short circuiting from top to bottom and bypassing normal wiring. These pathways are associated with Wolff-Parkinson-White syndrome. You probably don't have this, but i'd need to see an ekg to say for sure. ...Read more
Usually nothing.: The pr interval, the time between the P wave (atria contract) and the qrs (ventricles contract) is typically between 0.12 and 0.20 seconds. If it is a bit shorter than 0.12 seconds but the ECG is otherwise normal, there is generally nothing to be concerned about. If you have episodes of heart racing, you should tell your doctor, as there may be a condition in which you are prone to fast rhythms. ...Read more

Cardioversion: Cardioversion is not a procedure we would expect to correct a prolonged PR interval. ...Read more
In general no: If the heart rhythm problem is any type of heart block (first degree av block, second degree av block, or complete heart block), cardioversion won't help. Having said that, certain types of cardiac rhythm problem (such as atrioventricular nodal reentrant tachycardia (avnrt)) can in rare cases look like a fast heart rhythm with a long pr interval. These a cardioversion could correct. ...Read more
Ecg results- pr interval (110ms), qrs duration (90ms), qt, qtc- (352, 425), p-t-r axes- (8, 35, 110). Is this normal?
Usually benign: Pr interval depends on many factors. Pr shortens at faster hrs. Some people have short pr intervals even at slower rates, so-called "lgl syndrome", completely benign. Rarely, a short pr can be due to an accessory pathway, also called wpw, but any physician should be able to take one look at the ECG and determine if that's the case or not. Even if it is, there's nothing to do if you're asymptomatic. ...Read more
