The 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. This interval represents the onset of atrial depolarization to the onset of ventricular depolarization and consists of:
The normal PR interval, shown in Figure 10-4, is from 0.12 seconds. to 0.20* seconds in length. The PR interval is considered short when. it is less than or equal to 0.11 seconds (Figure 10-5), and prolonged. when it is more than 0.20 seconds (Figure 10-6). The interval should. be measured in the lead with the widest P wave and the widest QRS. complex in order to avoid the inadvertent omission of an isoelectric.
