CCT EXAM PRACTICE (EE) Questions & Answers
1. Which of the following leads would help to record the electrical activity inthe heart's
horizontal plane?
-Bipolar lead
-12-lead ECG
-Precordial leads
-Unipolar leads
Answer Precordial leads
This provides a transverse view through the middle of the heart which divides it intoupper and
lower portions.
2. Of the electrocardiogram waves, which would be considered the first deflec-tion after the
diastole that is produced because of the atrial depolarization?
-T wave

-S wave
-Q wave
-P wave
Answer P wave
This occurs because of the atrial depolarization of the heart.
3. The Bundle of His has an intrinsic firing rate of which of the following?
-40 to 60 beats per minute
-30 to 60 beats per minute
-60 to 80 beats per minute
-80 to 100 beats per minute
Answer 40-60 beats per minute
The Bundle of His is located at the superior portion of the interventricular septum. The Bundle
of His is actually the pathway of the electrical impulses that lead out ofthe SA node.

Hypoplastic when an organ is abnormally small because of a problem with devel-opment prior
to birth
Hypotension low blood pressure

Answer The center of the heart to the right arm
The center of the heart to the left leg
aVF The center of the heart to the left arm
aVL The center of the heart to the right arm
aVRFrom the left arm to the left leg lead III
