ANSWER- Innominate (proximal), left carotid, and the left subclavian (distal)
What cardiac pathology is associated with bicuspid aortic valves? - CORRECT ANSWER-
Coarctation of the Aorta
Where do the most aortic Coarctation occur? - CORRECT ANSWER- After the take-off of
the left subclavian artery, or within the aortic isthmus
Where are the pulmonary veins loca? Which ones are seen in this view? - CORRECT

, Know frequency for TEE probes versus TTE - CORRECT ANSWER- TTE probes are
usually higher 5-7MGz, while TTE probes are 2-7MHz
At what temperature is it unsafe to use a TEE probe? - CORRECT ANSWER- 40-45C
Know TEE views by esophageal level (know mid esophageal- ME and transgastric) and
degrees. - CORRECT ANSWER- 4ch- 0 degrees
2ch- 90 degrees

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
