The QT interval represents the time of ventricular activity including both depolarization and repolarization. It is measured from the beginning of the QRS complex to the end of the T wave. Normally, the QT interval is 0.36 to 0.44 seconds (9-11 boxes). The QT interval will vary with patient gender, age and heart rate. 2.

WebThe relation between heart rate and the duration of the PR interval is discussed in Chapter 19. The interval should be measured in the lead with the largest, widest P wave and the longest QRS duration. Such a selection avoids inaccuracies incurred by using the leads in which the early part of the P wave or QRS complex is isoelectric. formal hats for ladies
