IBHRE EXAM PREP 2026 FULL QUESTION
COLLECTION WITH EXPERT SOLUTIONS
◉ rad
Answer: radiation absorbed dose
=0.01 J absorbed/kg of any material (Gy)
=1/100 of a gray (Gy)
◉ REM
Answer: roentgen equivalent man, quantity of radiation received by
radiation workers
◉ AV delay
Answer: begins when the atrial escape interval times out and causes
a V pace (ApVp)
◉ PV delay
Answer: P tracking interval that is started by a sensed event in the
atrial channel (AsVp)
◉ Pacemaker Wenckebach
Answer: occurs when the p rate is faster than the max tracking rate
, ◉ AR delay (ventricular based timing)
Answer: -the sensed R wave causes the atrial escape interval timer
to start, so next atrial output is based on when and where the Rwave
is sensed
-may be faster than the programmed base rate
◉ AR delay (atrial based timing)
Answer: this begins by an atrial event, next atrial output will be at
the base rate
◉ PR delay
Answer: -occurs at fast sinus rates
-may see a longer AV delay, because device will not pace at a rate
higher than the max track rate
-on ECG this may look like first degree HB at a rate greater than the
programmed upper rate of the device
◉ Battery Longevity Calculation
Answer: =114(AHR battery capacity)/(current drain in uA)
◉ Ashman's Disease
