Webb6 feb. 2024 · Example 1. Marked first degree heart block. PR interval > 300 ms, P waves are buried in the preceding T wave. Example 2. Sinus bradycardia with 1st degree AV block. PR interval > 300 ms. Example 3. Normal sinus rhythm with 1st degree AV block. PR interval 260 ms. WebbThe normal PR interval range is ~120 – 200 ms (0.12-0.20s), although it can fluctuate depending on your age and health. The standard interval of the P wave can also range as low as ~90 ms (0.09s) until the onset of the QRS complex. The ECG for a child or a pregnant woman can also feature a shorter interval of the P wave.

WebbThis interval represents the time between the onset of atrial depolarization and the onset of ventricular depolarization. If the PR interval is >0.20 sec, there is an AV conduction block, which is called a first-degree heart block if each impulse from the atria can still be conducted into the ventricles.
