As a medical professional with expertise in cardiology, I can provide you with information on the normal QRS duration.
The normal QRS duration is typically between **0.06 to 0.10 seconds (60 to 100 milliseconds)** on an electrocardiogram (ECG). The QRS complex represents the depolarization of the ventricles, which is the initial phase of ventricular contraction. A QRS duration that falls outside of this range can indicate certain cardiac conditions or abnormalities.

The first measurement is known as the "P-R interval" and is measured from the beginning of the upslope of the P wave to the beginning of the QRS wave. ... The second measurement is the width of the QRS which should be less than 3 small squares, or less than 0.12 seconds in duration.
