Questions With 100% Verified Answers
The clinician programs the paced AV delay in the pacemaker to
200ms. What would be a recommended value for programming a
sensed AV delay? -
correct answer ✅175
Why is it important to optimize the AV delay when programming a
pacemaker? -
correct answer ✅To enhance hemodynamics
To allow sufficient time for ventricular filling and atrial kick
To prevent unnecessary ventricular pacing
TARP is the total atrial refractory period. What does it consist of? -
correct answer ✅AV delay + PVARP
What is the most important takeaway from the DAVID trial? -
correct answer ✅Right ventricular pacing can worsen heart
failure.
To have a PMT, a patient must have a dual chamber pacemaker,
retrograde conduction and a triggering event that breaks AV
synchrony. Which of the following is not a PMT trigger? -
correct answer ✅Magnet application

Questions With 100% Verified Answers
The postventricular blanking (PVAB) period is designed for what
function? -
correct answer ✅To prevent far-field R-wave oversensing
A typical setting for which parameter is 100ms? -
correct answer ✅PVAB
Which of the following is true about retrograde conduction? -
correct answer ✅It is transient
In general terms, how do PMT algorithms work? -
correct answer ✅They extend PVARP for one cycle when a
PVC is detected.
A pacemaker is programmed to an AV delay of 200ms and a PVARP
of 250ms and a base rate of 60ppm. How long is the alert period in
this pacemaker? -
correct answer ✅Not enough info to figure this out
What event will initiate a VBP on the ventricular channel? -
correct answer ✅An atrial paced event

Questions With 100% Verified Answers
What statement best describes the main purpose of the VBP? -
correct answer ✅To prevent crosstalk
To stop the ventricular channel from picking up the atrial pacing
spike
To avoid ventricular oversensing, double counting and
inappropriate inhibition
Which of the following is an example of crosstalk in a dual chamber
pacemaker? -
correct answer ✅Far-field R wave oversensing
You are handed a strip with a run of crosstalk. What annotated
pacing states do you primarily see? -
correct answer ✅Atrial paced event / ventricular sensed
event
What will you predominantly see on the tracing? -
correct answer ✅Atrial paced events with no ventricular
events
