Answer to Question 1

ANS: C
The two premature ventricular contractions shown are characterized by the absence of a P wave, wide QRS complexes, and a lack of T waves.

Answer to Question 2

ANS: A
Repolarization of the ventricles is represented by the T wave. The PR interval is the time it takes for the impulse initiated in the atria to travel through the atrioventricular node. The ST segment occurs during ventricular depolarization, and the QRS complex represents ventricular depolariza-tion.
