IBHRE CEPS Exam| Actual exam questions and 100% correct answers| Newest 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
