IBHRE CEPS TROUBLE EXAM QUESTIONS
AND ANSWERS
168. Is a temporary pacemaker's current or voltage constant when compared to a
permanent pacemaker? How much voltage can it generate? 5V or 20V? -
ANSWER Constant current of 20V. (Doubles 9.5 V)
171. Which patient with acute MI is most likely to require a temp pacemaker?
Inferior MI: Mobitz I AV Bock
inferior MI, bundle branch block.
Anterior MI: Mobitz I AV Bock.
ANSWER Anterior MI, bundle branch block.
Acute BBB after MI should be viewed as a warning sign and frequently
precedes CHB. The RCA frequently provides blood to the AV node, making the
impact of an anterior MI more substantial.
12. To ensure optimal electrical safety, the ECG monitored patient should be
_____________, and the monitor chassis should be _____________ or non-
conductive. (Grounded Versus Ungrounded) - ANSWER Ungrounded or
grounded.
34. Which channel is responsible for the SA and AV node upstroke? -
ANSWER CA++ Slow Channel
38. How does gender influence SVT frequency for AVNRT and AVRT? -
ANSWER Women are twice as likely as males to receive AVNRT.
39. The plateau (phase 2) appears on the surface ECG during the_________ and
mechanical ______________. - Answer QT interval, Systole.
48. The pause following atrial pacing is termed: - ANSWER: Overdrive
suppression.
49. What are the most common causes of arrhythmias in the EP lab?
, a. Vagal ANSWER b. Automaticity c. Triggered d. Reentry (ANSWER:
Reentry)
50. What is the mechanism behind "triggered" arrhythmias?
a. Reentry b. After depolarization c. Atrial tissue automation d. Ventricular
tissue automation - ANSWER: After depolarization (imagine R on T).
51. What do the terms EAD and DAD stand for, and what arrhythmias do they
refer to? - ANSWER EAD - Early after deporization, Torsades
DAD: Delayed after depolarization, RVOT VT.
55. In acutely unwell patients, which type of arrhythmia is most similar to a
"itch of the heart"? - ANSWER Automatic arrhythmias.

67. What exactly does tachypnea mean? - ANSWER Rapid breathing.
75. - Answer
96. - Answer
157. Which blade is most commonly used for the initial subcutaneous tissue
incision? (Looking for a number) - Answer: #10 scalpel blade.
169. Is the distal electrode of a pacing lead negative or positive? - ANSWER
Negative (Cat is negative)
