Chapter 11 Pacemaker Rhythms
Multiple Choice Questions
1. When is a ventricular pacemaker used?
A. When both ventricles are stimulated to contract
B. When the atria need to contract completely prior to the ventricles to allow for an atrial
kick C. When the conduction system from the AV node through the ventricles is intact
and functioning
D. When conduction in the ventricles is not working properly, to stimulate the ventricles to
contract
2. When is an atrial pacemaker used alone?
A. When the conduction system from the AV node through the ventricles is intact and
functioning
B. When both ventricles are stimulated to contract
C. When the atria need to contract completely prior to the ventricles to allow for an atrial
kick D. When conduction in the ventricles is not working properly
3. What is the advantage of atrioventricular pacing?
A. The conduction system from the AV node through the ventricles is intact and functioning
B. It mimics the normal cardiac conduction system and allows the atria to contract
completely prior to the ventricles to allow for an atrial kick
C. Both ventricles are stimulated to contract, compared to only the lower portion of the
right ventricle being stimulated
D. It delivers direct stimulation to the ventricles to produce a ventricular contraction
4. What portion of the heart do electronic pacemakers mimic?
A. Bundle of His
B. Purkinje fibers
C. SA node
,D. AV node
5. If the electronic pacemaker is set to 72 beats per minute and the AV node is firing at 58
beats per minute, what is the patient's heart rate?
A. 120
B. 58 C. 65
D. 72
6. What type of pacemaker is used for patients with heart failure?
A. Atrioventricular pacemaker
B. Atriobiventricular pacemaker
C. Ventricular pacemaker
D. Atrial pacemaker
7. What term refers to the ability of the heart muscle to respond to electrical stimulation
and depolarize the myocardial tissue?
A. Capture
B. Complexes
C. AV delay
D. Atrial kick
8. Which term indicates the mark on an ECG tracing that represents the stimulation of
electrical current from the pacemaker generator?
A. Oversense
B. Atrial capture
C. Triggered
D. Pacing spike
9. Which pacemaker rhythm has a pacing spike before P waves?
A. Ventricular pacemaker rhythm
B. Atrial pacemaker rhythm
, C. Atriobiventricular pacemaker rhythm

A. Ventricular pacemaker rhythm
B. Atrial pacemaker rhythm
C. Atriobiventricular pacemaker rhythm
D. Atrioventricular pacemaker rhythm
11. Which of the following is NOT one of the components to be evaluated on a pacemaker
tracing?
A. The chamber depolarization characteristics
B. The AV delay
C. The QT interval
D. The presence of atrial and/or ventricular spikes
12. If a patient is experiencing hypotension, lightheadedness, blackouts, and bradycardia,
what pacemaker complication may be occurring?
A. Malfunctioning
B. Malsensing
C. Loss of capture
D. Oversensing
13. Which pacemaker complication shows a pacing spike, but no waveform immediately
following it?
A. Malsensing
B. Malfunctioning
C. Loss of capture
D. Oversensing
