I was told anxiety and stress can cause a short PR interval on your EKG is this true? Is it dangerous?

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

Hello docs. I was wondering can Vyvanse (lisdexamfetamine) cause a shortened a pr interval?

Hello docs. I was wondering can Vyvanse (lisdexamfetamine) cause a shortened a pr interval?

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

Is having short pr interval serious?

Is having short pr interval serious?

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

What contributes to a prolonged or shortened pr interval?

What contributes to a prolonged or shortened pr interval?

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

Hello doctors, what does a short pr interval mean?

Hello doctors, what does a short pr interval mean?

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

Hello doctors, what does a short pr interval indicate?

Hello doctors, what does a short pr interval indicate?

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?

My pr interval is 100ms , my qt is 586. Hb is 85 waht happened to me. No symptoms at all..Is that normal?

Need clarification!: Your pr interval on the ekg is normal, while qt interval depends on many factors such as drugs you are taking, or electrolytes etc.I don't know what hb 85 means.I presume hb 8.5gm. It may mean you are anemic.Please clarify. If that is true consult md! ...Read more

How does shortened pr interval lead to svt?

How does shortened pr interval lead to svt?

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
