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 …
