Why is the SA node the primary pacemaker? Correct Answer: The SA node has the highest
intrinsic rate of any cardiac tissue.
, The save of contraction (depolarization) moves from the endocardium to the epicardium. Correct
Answer: Inside to outside. Look at the purkinje fibers above.
What is the absolute refractory state? Correct Answer: That period when a muscle cell is not
excitable- from phase 1 into phase 3; the 'relative refractory period' is during phase 3 and the
muscle cell might contract if the stimulus is strong.
Know what P wave, P-R interval, T wave represents Correct Answer: P wave- atrial systole
P-R interval- includes P-R segment (from atrial to ventricular depolarization)
QRS complex- ventricular diastole (repolarization)
What is the normal duration for the QRS complex? Correct Answer: 0.10 sec
Frank-Sterling Law Correct Answer: Increased volume= increased contractility
RUBBER BAND THEORY
Acute AI is hypercontractile because we shift up the Starling curve Correct Answer: Chronic AI
