SpletThe PR interval must not be too long nor too short. A normal PR interval ranges between 0.12 seconds to 0.22 seconds. The flat line between the end of the P-wave and the onset of the QRS complex is called the PR segment and it reflects the slow impulse conduction through the atrioventricular node. fly volantaSpletDepending where the pr interval began with is whether or not it will be shorter than normal.
