The PR interval is therefore a good estimate of AV node function...normal 120 to 200ms. You are correct the internet provides the parameters as you state...I relied on my memory!
A short PR interval can represent a heart rhythm disorder rhythm...early ventricular contractions, etc.
The PR interval represents the time from the onset of atrial contractions to the onset of ventricular contractions. "A short PR interval may also occur as a normal variant (unexplained noise in the system), although it is much more common in the pediatric population and at faster heart rates. In itself it is not dangerous". It may also cause heart rate varibility, skipped beats, double beats, etc.
Hpoe this helps!
Thank you for the info. i am surprised you mention 50-120 as the normal range......i have only seen 120-200 on the web, and ppl advised to see doctors at 80<x<120.........thats why i got nervous. Anyone else with similar experience?
Normal range for p-r interval is 50-120 ms. Your representaton of 112ms and 116ms is within the normal range.
Hope this helps.
