Physician-Level Examination with Detailed
Rationales||Newest Exam!!
39. The plateau (phase 2) occurs on the surface ECG
during the_________ , and during mechanical
_________________ . - Answer-QT interval, Systole
48. The pause after atrial pacing is termed: - Answer-
Overdrive suppression
49. Most arrhythmias in the EP lab are caused by?
a. Vagal response
b. Automaticity
c. Triggered
d. Reentry - Answer-Reentry
50. What mechanism causes "triggered" arrhythmias?
a. Reentry
b. After depolarization
,2|Page
c. Automaticity of the atrial tissue
d. Automaticity of the ventricular tissue - Answer-After
depolarization (think R on T)
51. What do the terms EAD and DAD stand for and what
arrythmias are they associated with? - Answer-EAD - Early
after deporization, Torsades
DAD - Delayed after depolarization, RVOT VT
55. Which arrhythmia type most closely resembles an "itch
of the heart" in acutely ill patients? - Answer-Automatic
arrhythmias
63. An ambulatory patient is: - Answer-Able to walk
67. What does tachypnea mean? - Answer-Rapid
breathing
168. Compared to the the permanent pacemaker, does a
temp pacer have constant current or voltage? Also, how
much voltage can it generate? 5V or 20V? - Answer-
Constant current, 20V. (Doubles 9.5V)
171. Which patient with acute MI is most likely to need a
temp pacer?
,3|Page
Inferior MI, Mobitz I AV Bock
Inferior MI, bundle branch block
Anterior MI, Mobitz I AV Bock
Anterior MI, bundle branch block - Answer-Anterior MI,
bundle branch block
Acute BBB post MI should be seen as a warning and often
proceeds CHB. The RCA commonly supplies blood to the
AV node making the impact of an Anterior MI more
significant
12. For maximum electrical safety, the ECG monitored
patient should be _____________, and the monitor
chassis should be _______________ or non-conductive.
(Grounded vs Ungrounded) - Answer-Ungrounded,
grounded
34. What channel is responsible for the SA and AV node
upstroke? - Answer-Ca++ Slow Channel
38. How does gender effect SVT frequency for AVNRT and
AVRT? - Answer-Women twice as likely to get AVNRT,
men twice as likely to get AVRT
, 4|Page
157. What blade is most often used for the initial
subcutaneous tissue incision? (Looking for a number) -
Answer-#10 scalpel blade
169. The distal electrode of a pacing lead is negative of
positive? - Answer-Negative (Cat = negative)
170. If you press emergency pacing on the MDT temp
pacer, what rate does it pace at? - Answer-Whatever rate
you have currently programmed. (Not just always 60)
173. A pulse train of 8 paced beats with a fixed cycle
length is termed:
a. Incremental Pacing
b. Decremental Pacing
c. Synchronous Pacing
d. Asynchronous Pacing - Answer-a. Incremental Pacing -
Also known as bust pacing
178. The new RF powered transseptal needle that may be
used to puncture a fibrotic and aneurysmal atrial septum
has:
