The QRS time-interval maximum is which value?

Explanation:
QRS duration reflects how long it takes for the ventricles to depolarize. In a healthy adult, this interval is normally up to about 0.12 seconds (120 milliseconds). That makes 0.12 seconds the maximum normal value. A shorter QRS, like 0.08 seconds, is still normal but not the maximum. Longer intervals, such as 0.16 or 0.20 seconds, indicate a conduction delay within the ventricles (for example, a bundle branch block or other intraventricular conduction abnormality).
