Web4 de fev. de 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 … WebIn electrocardiography, the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms).

WebThe QT interval is the time from the beginning of the QRS complex until the end of the T wave. The “normal” QT length varies with heart rate. Very fast rates shorten the QT length.
