Quizplus · Accepted Answer

To determine if a rhythm is regular or irregular, you need to measure the distance between the R waves (or R-R intervals) across the entire strip. If these intervals are consistent, the rhythm is regular, and if they vary in length, the rhythm is irregular. Measuring QRS complexes, PR intervals, or PR segments may be important for other aspects of the ECG interpretation, but they do not provide information about the regularity of the rhythm.
