How to measure the QT interval--what is normal? The QT interval extends from the beginning of the QRS complex to the end of the T wave. Since the report of Jervell and Lange-Nielsen in 1957, it has been difficult to determine whether to measure a QT or a QU interval. U waves are ...

QRS complex: 0.04 to 0.06 seconds Interpretation: Sinus tachycardia Sinus tachycardia is a normal response of the heart to the body's demand for increased blood flow. The sinus node increases its rate in response to the needs of the body. When these needs no longer exist, the heart rate sl...

What is the qt interval and how should it be measured? The QT interval on the surface ECG is measured from the beginning of the QRS complex to the end of the T wave. Thus, it is the electrocardiographic manifestation of ventricular depolarization and repolarization. This electrical activity ...
