The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. The normal PR interval is between 120 – 200 ms (0.12-0.20s) in duration (three to five small squares). If the PR interval is > 200 ms, first degree heart block is said to be present.

WebFirst-degree AV block is an abnormal delay in conduction through the AV node. This type of AV block is a disturbance in the conduction between the normal sinus impulse and its eventual ventricular response. This manifests as a prolonged PR interval on ECG. Meanwhile, the heart is maintained in sinus rhythm, with a normal QRS configuration.
