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.
