WebFeb 4, 2024 · 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 ventricular in … Web• At least one common ECG lead must be deemed acceptable for all tested postures. At a minimum, Supine and Standing/Sitting postures must be tested. Reasons for failure include: R waves too small The average amplitude of the R wave peaks was too small Score too low due to large R waves The average amplitude of the R-wave peaks was too large
