IBHRE CEPS ExamOhm's law equation - ANS V=IR
EKG monitored patient should be __________, monitor chassis should be ___________
(nonconductive). Why - ANS ungrounded, grounded. Grounded patient would be able to conduct
leakage currents. we dont want this
lb to kg - ANS 2.2 lb = 1 kg
F to C - ANS C=5/9(F-32)
C to F - ANS F=9/5C+32
3 things that change automaticity of automatic cells - ANS 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 - ANS QT interval
What is main ion transfer during systole - ANS K+ seeps out, Ca2+ enters
At rest, what is intracellular/extracellular environment - ANS inside negative, outside positive
What phase of AP is resting membrane potential - ANS phase 4
,Nodal depolarization occurs via what channel - ANS Ca2+ slow channel
Cardiac muscle cell depol occurs via what channel - ANS Na+ fast channel
During which phases is cell refractory - ANS 1,2,3
TDP caused by what mechanism usually - ANS EAD's (triggered activity)
Variance - ANS Take each number in sample, subtract each number from mean, square each difference,
add all, divide sum by number in sample -1
Standard deviation - ANS square root of variance
P value - ANS 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 - ANS Kaplan - Meier curves
when measuring EGM's, earliest atrial activation usually from _____ and earliest ventricular usually from
______ - ANS P wave / QRS
Morady maneuver is used to differentiate - ANS differentiate AT from AVNRT/AVRT
Most common arrhythmia - ANS AF
Most common SVT - ANS AVNRT
, What type of single use devices can be resterilized and why? - ANS Diagnostic EP electrodes because
lumen and technically not a catheter because no lumen
Fr to mm - ANS 1 Fr = .33 mm
Tip inner diameter standard diagnostic cardiac catheters and why - ANS .038 inch / because it is
supposed to be used with .035-.038 inch guide wires
What is 2 rules for CMC's like spiral or lasso - ANS 1. Only approved for use in LA due to chordae
tendinea
2. Only rotate shaft clockwise
Stereotaxis catheters - ANS Have magnets in tip for maneuverability in response to changes in magnetic
field
What system remotely steers guided catheters - ANS Hansen robotic system
ACT for using array - ANS ACT 250-300
bipolar cardiac electrodes record local _________ that occur during phase _______ - ANS
depolarizations / phase 0
surface EKG leads usually filtered at what - ANS .1 - 100 Hz
Normal EGM filter settings - ANS 30 - 300 Hz
What to do if T waves interfere with A/V and why - ANS Increase the high pass filter because T waves
are lower frequency as well as far field
