Quizplus · Accepted Answer

In AV blocks where there is a consistent delay in the conduction of the electrical signal between the atria and the ventricles, the P-P interval (the time between consecutive P waves, representing atrial depolarization) remains regular. The R-R interval (the time between consecutive R waves, representing ventricular depolarization) may or may not be regular depending on the degree of block. Therefore, choice A is the best answer.

In AV Blocks,the P-P Interval Is
