potential
a systole is represented by what portion of the ECG - Answer - c QT interval
What is main ion transfer during systole - Answer - c K+ seeps out, Ca2+ enters
At rest, what is intracellular/extracellular environment - Answer - c inside
negative, outside positive
What phase of AP is resting membrane potential - Answer - c phase 4
Nodal depolarization occurs via what channel - Answer - c Ca2+ slow channel
Cardiac muscle cell depol occurs via what channel - Answer - c Na+ fast channel
During which phases is cell refractory - Answer - c 1,2,3
TDP caused by what mechanism usually - Answer - c EAD's (triggered activity)
Variance - Answer - c 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 - c square root of variance
,P value - Answer - c 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 - Answer c
Kaplan - Meier
curves
What is 2 rules for CMC's like spiral or lasso - Answer - c 1. Only approved for
use in LA due to
chordae tendinea
2. Only rotate shaft clockwise
Stereotaxis catheters - Answer - c Have magnets in tip for maneuverability in
response to changes
in magnetic field
when measuring EGM's, earliest atrial activation usually from _____ and earliest
ventricular usually
from ______ - Answer - c P wave
/ QRS
Morady maneuver is used to differentiate - Answer - c differentiate AT from
AVNRT/AVRT

What system remotely steers guided catheters - Answer - c Hansen
robotic system ACT for using array - Answer - c ACT 250-300
bipolar cardiac electrodes record local _________ that occur during phase
_______ - Answer - c
, depolarizations /
phase 0
