SpletPR interval. In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed ... SpletShort PR interval (less than 120 milliseconds [msec]). Slight widening of the QRS complex due to slurred upstroke (delta wave) of the QRS complex.

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.
