Answer to Question 1

ANS: C
The wave of repolarization occurring in the ventricles immediately after depolarization is the T wave.

Answer to Question 2

ANS: B
The normal QRS complex is not wider than 3 mm (0.12 sec) because of the rapid movement of the impulse through the ventricles by the bundle branches and Purkinje fibers.
