Question

Quizplus · Accepted Answer

Regularity of a rhythm is determined by measuring the R-R intervals, which represent the distance between consecutive R waves (or Q waves if present). P-P intervals and distance between consecutive U waves are not commonly used to determine rhythm regularity. QRS intervals are used to measure the duration of ventricular depolarization, but not to determine rhythm regularity.
