WebbThe PR interval on the electrocardiogram represents the time that it takes an impulse to travel through the atrium and atrioventricular (AV) conduction system to the ventricles. Normally, activation is slowest in the AV node, and variations in PR interval most commonly parallel changes in AV nodal a …

Webb15 feb. 2024 · The PR interval is the time between atrial depolarisation and ventricular depolarisation. It is an indicator of atrioventricular conduction time, involving conduction from the atria, through the AV node and down the His-Purkinje system. Normal Duration; 120-200ms (3-5mm) WebbThe normal PR interval is from 0.12-0.2 seconds and is measured on the EKG from the beginning of the P wave to the beginning of the QRS complex.
