What is a typical range for a normal QRS duration?

A normal QRS duration typically falls within the range of 0.06 to 0.10 seconds. This measurement represents the time it takes for the ventricles to depolarize and is an essential parameter in diagnosing various cardiac conditions. A duration longer than this range can indicate issues such as a bundle branch block or other forms of intraventricular conduction delay, while a duration shorter than this range is often less common and might indicate an abnormality in ventricular conduction pathways. Recognizing this range helps healthcare providers assess the heart's electrical activity and overall function accurately.
