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.
