a systole is represented by what portion of the ECG - (answer)QT interval
What is main ion transfer during systole - (answer)K+ seeps out, Ca2+ enters
At rest, what is intracellular/extracellular environment - (answer)inside negative, outside positive
What phase of AP is resting membrane potential - (answer)phase 4
Nodal depolarization occurs via what channel - (answer)Ca2+ slow channel
Cardiac muscle cell depol occurs via what channel - (answer)Na+ fast channel
,IBHRE CEPS EXAM 2025 QUESTIONS WITH 100% SOLVED ANSWERS!!
During which phases is cell refractory - (answer)1,2,3
TDP caused by what mechanism usually - (answer)EAD's (triggered activity)
Variance - (answer)Take each number in sample, subtract each number from mean, square each
difference, add all, divide sum by number in sample -1
Standard deviation - (answer)square root of variance
P value - (answer)Probability of certainty / smaller p value means the more likely the result could not
occur by chance

when measuring EGM's, earliest atrial activation usually from _____ and earliest ventricular usually from
______ - (answer)P wave / QRS
Morady maneuver is used to differentiate - (answer)differentiate AT from AVNRT/AVRT
Most common arrhythmia - (answer)AF
Most common SVT - (answer)AVNRT
What type of single use devices can be resterilized and why? - (answer)Diagnostic EP electrodes because
lumen and technically not a catheter because no lumen
Fr to mm - (answer)1 Fr = .33 mm
, IBHRE CEPS EXAM 2025 QUESTIONS WITH 100% SOLVED ANSWERS!!
Tip inner diameter standard diagnostic cardiac catheters and why - (answer).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 - (answer)1. Only approved for use in LA due to chordae
tendinea
2. Only rotate shaft clockwise
Stereotaxis catheters - (answer)Have magnets in tip for maneuverability in response to changes in
magnetic field
What system remotely steers guided catheters - (answer)Hansen robotic system
ACT for using array - (answer)ACT 250-300
bipolar cardiac electrodes record local _________ that occur during phase _______ -
(answer)depolarizations / phase 0
surface EKG leads usually filtered at what - (answer).1 - 100 Hz
Normal EGM filter settings - (answer)30 - 300 Hz
What to do if T waves interfere with A/V and why - (answer)Increase the high pass filter because T
waves are lower frequency as well as far field
Unipolar filter setting - (answer).05 - 300 Hz
