F to C - CORRECT ANSWER-C=5/9(F-32)
C to F - CORRECT ANSWER-F=9/5C+32
3 things that change automaticity of automatic cells - CORRECT ANSWER-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 - CORRECT ANSWER-QT
interval
,What is main ion transfer during systole - CORRECT ANSWER-K+ seeps out,
Ca2+ enters
At rest, what is intracellular/extracellular environment - CORRECT ANSWER-
inside negative, outside positive
What phase of AP is resting membrane potential - CORRECT ANSWER-phase
4
Nodal depolarization occurs via what channel - CORRECT ANSWER-Ca2+ slow
channel
Cardiac muscle cell depol occurs via what channel - CORRECT ANSWER-Na+
fast channel
During which phases is cell refractory - CORRECT ANSWER-1,2,3
TDP caused by what mechanism usually - CORRECT ANSWER-EAD's (triggered

Variance - CORRECT 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 - CORRECT ANSWER-square root of variance
P value - CORRECT ANSWER-Probability of certainty / smaller p value means
the more likely the result could not occur by chance
