WebFeb 4, 2024 · QRS Width. Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects). The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < 100 ms) are supraventricular in origin. Broad complexes (QRS > 100 ms) may be either … Prolongation of QRS duration implies that ventricular depolarization is slower than normal. The QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a significant … See more Naming of the waves in the QRS complex is easy but frequently misunderstood. The following rules apply when naming the waves: 1.
