Question

Quizplus · Accepted Answer

With second-degree AV block type II the ventricular rhythm is irregular. There are more P waves than QRS complexes and the P-P interval is regular. P waves are normal in size and shape, but some P waves are not followed by a QRS complex. The PR interval may be within normal limits or prolonged, but it is constant for the conducted beats; the PR intervals before and after a blocked P wave are constant.
