What pulmonary veins are viewed in apical 4 chamber? - CORRECT ANSWER ✔✔-
Lower pulmonary veins
What pulmonary veins are viewed in apical 5 chamber? - CORRECT ANSWER ✔✔-
Upper pulmonary veins
From the apical 4 chamber view how do you rotate the transducer to obtain the
apical LAX? - CORRECT ANSWER ✔✔- clockwise 120 degrees
Where is the coronary sinus located? - CORRECT ANSWER ✔✔- posterior AV
groove
1
,Which view do you use to evaluate the coronary sinus? - CORRECT ANSWER ✔✔-
PLAX
To visualize the coronary sinus in the apical 4 chamber view you should tilt the
transducer: - CORRECT ANSWER ✔✔- posterior
Which valve sits at the opening of the coronary sinus? - CORRECT ANSWER ✔✔-
Thebesian
What valve sits at the opening of the IVC? - CORRECT ANSWER ✔✔- Eustachian
Where is the Chiari network located? - CORRECT ANSWER ✔✔- Right atrium

CORRECT ANSWER ✔✔- A wave
At what temperature is it unsafe to use a TEE probe? - CORRECT ANSWER ✔✔-
40-45 degrees celcius (Above 41 degrees celcius)
Which electrical pathway has the fastest intrinsic rate? - CORRECT ANSWER ✔✔-
SA node
What is the absolute refractory state? - CORRECT ANSWER ✔✔- period when a
muscle cell is not excitable; occurs from phase 1 into phase 3
2
,What is a normal duration for the QRS complex? - CORRECT ANSWER ✔✔- 0.10
sec or 100 msec
This is known as the rubber band theory - CORRECT ANSWER ✔✔- Frank Starling
Law
What occurs during preload? - CORRECT ANSWER ✔✔- Filling

ANSWER ✔✔- Tricuspid valve
Where does the LAD lie on the heart? - CORRECT ANSWER ✔✔- Anterior
interventricular groove (sulcus)
What aortic cusp is superior in PLAX view? - CORRECT ANSWER ✔✔- RCC
What aortic cusp is posterior in PLAX view? - CORRECT ANSWER ✔✔- NCC
From the left parasternal window which of the following are you most likely to get
accurate velocity measurments? - CORRECT ANSWER ✔✔- Pulmonary artery
What view gives the most accurate velocities of the PV/pulmonary artery? -
CORRECT ANSWER ✔✔- PSAX; short axis
