Answer to Question 1

C
Second-degree 2:1 AV block is characterized by regular P-P and R-R intervals. P waves are normal in size and shape, but every other P wave is not followed by a QRS. The atrial rate is twice the ventricular rate.

Answer to Question 2

A
The intrinsic rate of an idioventricular rhythm, which is also called a ventricular escape rhythm, is 20 to 40 beats/min (i.e., the intrinsic firing rate of the Purkinje fibers).
