Answer to Question 1

A
Sensitivity refers to the extent to which an artificial pacemaker recognizes intrinsic cardiac electrical activity.

Answer to Question 2

A
The QT interval is measured from the beginning of the QRS complex to the end of the T wave. In the absence of a Q wave, the QT interval is measured from the beginning of the R wave to the end of the T wave. The term QT interval is used regardless of whether the QRS complex begins with a Q or R wave.
