,Q1 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
In a patient with a dual-chamber pacemaker programmed to DDD mode, which of
the following atrial sensing issues would most likely result in a
pacemaker-mediated tachycardia (PMT) if the PVARP is too short?
A. Atrial undersensing leading to inappropriate ventricular pacing
B. Retrograde P-wave sensing in the atrial channel CORRECT
C. Far-field R-wave oversensing in the atrial channel
D. Loss of atrial capture with intrinsic AV conduction
RATIONALE: A short PVARP allows sensing of retrograde P-waves, triggering ventricular pacing
that perpetuates PMT. Atrial undersensing causes loss of atrial tracking, not PMT. Far-field
R-wave oversensing can inhibit atrial pacing but does not initiate PMT. Loss of atrial capture does
not create a reentrant loop.
Q2 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
Which of the following best explains the mechanism by which cardiac
resynchronization therapy (CRT) improves left ventricular (LV) function in patients
with left bundle branch block (LBBB)?
A. Pre-excitation of the LV lateral wall to reduce mechanical dyssynchrony CORRECT
B. Shortening of the PR interval to optimize AV delay
C. Increased heart rate to augment cardiac output
D. Suppression of ventricular arrhythmias via overdrive pacing
RATIONALE: CRT biventricular pacing pre-excites the LV lateral wall, counteracting the delayed
activation in LBBB and improving synchrony. AV delay optimization helps but is secondary. Heart
rate increase is not the primary mechanism. CRT does not primarily suppress arrhythmias.

,Q3 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
A patient with an implantable cardioverter-defibrillator (ICD) receives a shock.
Interrogation shows a sudden onset of a rapid regular tachycardia at 240 bpm with
stable cycle length. Which of the following is the most appropriate next step to
differentiate ventricular tachycardia (VT) from supraventricular tachycardia (SVT)?
A. Examine the morphology of the stored electrograms CORRECT
B. Assess the response to antitachycardia pacing (ATP)
C. Evaluate the patient's symptoms during the event
D. Check the tachycardia cycle length stability
RATIONALE: Morphology matching with the baseline rhythm is a key discriminator: VT typically
has a different morphology. ATP response may terminate VT but does not always differentiate.
Symptoms are non-specific. Cycle length stability helps but is not definitive.
Q4 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
Which of the following MRI conditions is considered a contraindication for a
patient with a legacy (non-MRI-conditional) pacemaker?
A. MRI of the brain at 1.5 Tesla
B. MRI of the knee at 3 Tesla
C. MRI of the abdomen with the device in the field of view CORRECT
D. MRI of the chest with the device outside the field of view
RATIONALE: MRI of the abdomen with the device in the field of view poses significant risk of
heating and lead-tip heating. Brain and knee MRIs are often considered lower risk if the device is
outside the field, but still require careful risk-benefit. Chest MRI with device outside field is not a
contraindication per se. However, the presence of the device in the field is a major
contraindication for legacy systems.

, Q5 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
A device clinic receives remote transmissions from a patient with a CRT-D. Which
of the following findings would most likely indicate a clinically significant change
warranting immediate in-person evaluation?
A. Decrease in atrial lead sensing amplitude from 3.5 mV to 3.0 mV
B. Increase in right ventricular pacing threshold from 1.0 V to 1.5 V at 0.4 ms
C. Stable thoracic impedance with a 10% decline in daily activity
D. New onset of frequent non-sustained VT (NSVT) with episodes > 30 seconds CORRECT
RATIONALE: NSVT episodes lasting >30 seconds are considered sustained and require prompt
evaluation. A 0.5 V threshold increase is not alarming. Stable impedance with activity decline is
not urgent. Atrial sensing decrease is minor.
Q6 ANALYZE COMPLEX CIED ELECTROGRAMS AND DIAGNOSTIC DATA TO GUIDE
CLINICAL DECISIONS
Which of the following statements best describes the recommended programming
of the atrial-based pacing mode in patients with sinus node dysfunction and intact
AV conduction?
A. DDD mode with a short AV delay to ensure ventricular capture
B. AAI mode with a long AV delay to minimize ventricular pacing CORRECT
C. DDD mode with rate-responsive pacing to improve exercise tolerance
D. VVI mode with rate-responsive pacing to simplify programming
RATIONALE: In sinus node dysfunction with intact AV conduction, AAI mode (or DDD with long
AV delay) is preferred to avoid unnecessary right ventricular pacing, which can cause
dyssynchrony. DDD with short AV delay increases ventricular pacing. Rate-responsive is not the
primary concern. VVI is not preferred due to loss of AV synchrony.
