IBHRE PRACTICE EXAM #1
What is the national incidence of pacemaker pocket infection? - ANSWERS-<2%
Acutely, the most frequently identified microorganisms from pacemaker pocket
infections are: - ANSWERS-Staphylococcus aureus
An early discrete hematoma at the pacemaker site which does not compromise
the skin integrity of the suture line should be treated by: - ANSWERS-Observation
A potential complication of single lead VDD pacing is: - ANSWERS-Pacemaker
syndrome
Overdrive pacing is the preventative treatment of choice for: - ANSWERS-
Torsades de pointes
The most common cause of pacemaker erosion is: - ANSWERS-Indolent infection
First diagnostic tool you should think of when physician thinks he might have
perforated the myocardium - ANSWERS-Echocardiogram
Clavicular pinching on the pacing electrode is most common with the following
transvenous implantation approach? - ANSWERS-Subclavian vein puncture
, Trifascicular block is what class of indication? - ANSWERS-Class I
A patient with rheumatic heart disease has two prosthetic valves (mitral and
tricuspid). Which of the following leads should be implanted? - ANSWERS-
Epicardial
Ventricular Arrhythmias associated with QT prolongation syndrome are best
suited to - ANSWERS-Overdrive suppression
A CHB pt with DR PM was recently placed on propranolol. What feature would
provide optimal benefit to this pt? - ANSWERS-Sensor enabled
Wenkebach window - ANSWERS-Max tracing interval(in ms) - TARP(in ms)
2:1 Block Point - ANSWERS-60,000/TARP
Basic unit of capacitance - ANSWERS-Farad
Function of pacemaker circuitry that allows the pacemaker output pulse to be
dissipated quickly maximizing both output and sensing capabilities - ANSWERS-
Charge dump
