Complete the following.
____ 1. Pacing interval is the time measured between two consecutive paced beats in the same
heart chamber.
____2. Escape interval is the time measured between a sensed cardiac event and the next
pacemaker beat.
____3. Intrinsic beat is the naturally occurring beat/rhythm.
____4. SSS and CHB are indications for insertion of a permanent pacemaker.
____5. TCP is a pacemaker surgically implanted in the body.
____6. VVI pacemaker code indicates ventricles are sensed and inhibited.
____7. Ventricular pacing is accomplished by placing the pacing electrode in the right ventricle.
____8. Fixed-rate pacemakers are not often used today.
____9. Contraindication for TCP is a flail chest.
____10. The paced interval and escape interval will not measure the same.

3. Seen on the ECG monitor is an absence of pacemaker spikes even though the patient’s
intrinsic rate is less than that of the pacemaker and a return of the underlying rhythm
for which the pacemaker was implanted is known as
a. Failure to pace
b. Failure to sense
c. Oversensing
4. Complications of temporary transvenous pacing include:
a. Bleeding, infection and MI
b. Pneumothorax and cardiac dysrhythmias
c. All of the above
5. Pacemaker spikes that follow too closely behind the patient’s QRS complexes is known
as
a. Oversensing
b. Failure to sense
c. Failure to capture
6. With TCP, the pacing rate is set for
a. 60 – 80 bpm
b. 100 – 150 bpm
c. 30 – 50 bpm
7. Seen on the ECG is a pacemaker spike not followed by P wave (if lead in the atrium) or
QRS complex (if lead in the right ventricle) is known as
a. Failure to sense
b. Failure to capture
c. Undersensing
8. Causes for pacemaker malfunction include
a. Battery failure, fractured pacing lead, and displacement of the electrode tip
b. Pulse generator failure, a broken or loose connection between the pacing lead
and the pulse generator
c. All of the above

9. When pacemaker spikes occur at a rate slower than the pacemaker’s preset rate or no
paced beats even though the pacemaker’s preset rate is greater than the patient’s
intrinsic rate is known as

10. Successful depolarization of the atria and/or ventricles by an artificial pacemaker is
known as
