IBHRE CEPS Exam Questions and
Answers 100% Pass
Ohm's law equation - ✔✔V=IR
EKG monitored patient should be __________, monitor chassis should be ___________
(nonconductive). Why - ✔✔ungrounded, grounded. Grounded patient would be able to
conduct leakage currents. we dont want this
lb to kg - ✔✔2.2 lb = 1 kg
F to C - ✔✔C=5/9(F-32)
C to F - ✔✔F=9/5C+32
3 things that change automaticity of automatic cells - ✔✔1. slope of phase 4
2. Change of threshold potential
3. Change of resting membrane potential
a systole is represented by what portion of the ECG - ✔✔QT interval
What is main ion transfer during systole - ✔✔K+ seeps out, Ca2+ enters
At rest, what is intracellular/extracellular environment - ✔✔inside negative, outside
positive
What phase of AP is resting membrane potential - ✔✔phase 4

, Nodal depolarization occurs via what channel - ✔✔Ca2+ slow channel
Cardiac muscle cell depol occurs via what channel - ✔✔Na+ fast channel
During which phases is cell refractory - ✔✔1,2,3
TDP caused by what mechanism usually - ✔✔EAD's (triggered activity)
Variance - ✔✔Take each number in sample, subtract each number from mean, square
each difference, add all, divide sum by number in sample -1
Standard deviation - ✔✔square root of variance
P value - ✔✔Probability of certainty / smaller p value means the more likely the result
could not occur by chance
survival curve showing % of patients surviving treatment over time - ✔✔Kaplan -
Meier curves
when measuring EGM's, earliest atrial activation usually from _____ and earliest
ventricular usually from ______ - ✔✔P wave / QRS
Morady maneuver is used to differentiate - ✔✔differentiate AT from AVNRT/AVRT
Most common arrhythmia - ✔✔AF
Most common SVT - ✔✔AVNRT
What type of single use devices can be resterilized and why? - ✔✔Diagnostic EP
electrodes because lumen and technically not a catheter because no lumen
Fr to mm - ✔✔1 Fr = .33 mm
Tip inner diameter standard diagnostic cardiac catheters and why - ✔✔.038 inch /
because it is supposed to be used with .035-.038 inch guide wires
