2. Change of threshold potential
3. Change of resting membrane potential
a systole is represented by what portion of the ECG - Precise Answer
✔✔QT interval
,What is main ion transfer during systole - Precise Answer ✔✔K+ seeps
out, Ca2+ enters
At rest, what is intracellular/extracellular environment - Precise Answer

TDP caused by what mechanism usually - Precise Answer ✔✔EAD's
(triggered activity)
Variance - Precise 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 - Precise Answer ✔✔square root of variance
