A short PR interval can be seen when the AV node delay is bypassed, such as in Wolff-Parkinson-White syndrome or Lown-Ganong-Levine syndrome.
The normal PR interval measures 0.12-0.20 seconds (120-200 milliseconds). A prolonged or shortened PR interval can indicate certain disease. When prolonged, a first degree AV block is present.
