   4 lut 2021 · The PR interval is the time from the onset of the P wave to the start of the QRS complex. It reflects conduction through the AV node. The normal PR interval is between 120 – 200 ms (0.12-0.20s) in duration (three to five small squares). If the PR interval is > 200 ms, first degree heart block is said to be present.

   19 maj 2024 · The PR interval includes the atrial depolarization and the propagation of the impulse through the AV node and the Conduction System until the ventricular myocardium begins to depolarize 1. It does not include the duration of conduction from the Sinus Node to the right atrium (Sinoatrial conduction).

   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 the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal. The isoelectric (flat) line between the end of the P-wave and the start of the QRS complex is called the PR segment.

   The PR interval is assessed in order to determine whether impulse conduction from the atria to the ventricles is normal in terms of speed. The PR interval must not be too long nor too short. A normal PR interval ranges between 0.12 seconds to 0.22 seconds.

   19 maj 2024 · The PR interval represents the atrial depolarization and physiological delay of the stimulus in the atrioventricular (AV) node. It is measured from the beginning of the P wave until the beginning of the Q or R wave. Its normal value is between 0.12 s and 0.20 s.

   The PR interval is a measurement of the time it takes from the start of the p wave to the start of the QRS complex, typically 3-5 mm in duration. This interval is representative of the physiologic delay caused by transmission of impulses through the AV node.
