As a medical professional with expertise in cardiology, I can provide you with information on the QRS complex. The QRS complex on an electrocardiogram (ECG) represents the depolarization of the ventricles, which is the initial phase of ventricular contraction. The duration of the QRS complex can vary, but under normal circumstances, it should be less than 120 milliseconds (0.12 seconds). Prolonged QRS duration can be indicative of certain cardiac conditions or conduction abnormalities.

The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds �� that is, 80 and 100 milliseconds. When the duration is between 0.10 and 0.12 seconds, it is intermediate or slightly prolonged. A QRS duration of greater than 0.12 seconds is considered abnormal.
