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. blaxploitation lyrics
