CCDS exam review Questions and Correct Answers |
Latest Update
What lead insulation materials are known for reducing fibroblast
ingrowth and susceptibility to Metal-ion induced oxidation (MIO) and
Environmental Stress-Cracking (ESC)
Ans: ePTFE and 80A polyurethane
What is the most common cause of safety pacing or "ventricular safety
standby?"
Assignment Expert
Ans: Ventricular Ectopy
Guru01 - Stuvia
Ventricular safety standby is a feature designed to avoid the
inappropriate inhibition of V-pacing due to crosstalk oversensing of an
Ap event on the ventricular EGM. Not sure why the book says that PVCs
are the most common cause, perhaps because bipolar leads have made

Crosstalk such a rare-occurring issue now.
Which electrode material is most likely to result in higher pacing

thresholds and higher degree of polarization?
Ans: Elgiloy
What phase of the action potential correlates to relative refractory
period?
Ans: 3
The ventriculoatrial conduction time of a pacemaker patient with a
typical endless-loop-tachycardia may be calculated by which equation?
Ans: (upper rate limit interval) - ( AV delay + PVARP) ????????????????
or is it just MTR (URL) - AVD

For treatment of arrhythmias, most drugs work by altering _______ or
__________.
Ans: Conductivity or Rerfractoriness
1Hz = ??bpm
Ans: 60bpm
What would cause a more significant drain on battery charge... ATP
before charge or ATP during charge?
Ans: ATP DURING charge
Assignment Expert
