Short PR interval:
•WPW syndrome
•Nodal rhythm

PR Interval: Short (< 0.12 sec)

QRS: Narrow and Delta wave present

WPW there is accessory conduction pathway between the atria and the ventricles.

 So impulses are rapidly conducted to the ventricles. So short PR interval and

there is slurring of the initial portion of the QRS called the delta wave
