Correct Answers | Verified 2024 Version
What is the major difference between protocols for cardiac treadmill and claudication treadmill testing?
- ✔✔Speed is varied during a cardiac treadmill test to increase heartrate to a specific target level.
During a treadmill test, patient complains of pain in the left arm and jaw, but denies any other pain.
What is the most likely consideration? - ✔✔Angina.
What is the normal diameter for the abdominal aorta? - ✔✔2-3 cm.
After walking 5 minutes on treadmill, patient experiences decrease in ankle pressure of 40% on right and
15% on left. These findings suggest? - ✔✔Claudication.
What is the correct setting for arterial volume recording? - ✔✔AC-coupled output.
What Doppler waveform abnormality in the lower extremity arterial circulation distal to a
hemodynamically significant stenosis show? - ✔✔An absent flow recersal component, blunting of the
peak velocity and prolonged upslope and downslope.
A normal arterial volume waveform may have all EXCEPT: Swift upstroke, sharp peak, rapid downslope
bowed toward baseline, dicrotic notch or reverse flow component? - ✔✔Reverse flow component
because it is part of a Doppler waveform not volume waveform.
T or F- Most analog Doppler analysis is qualitative, assessing for presence or absence of characteristics. -
✔✔True.
What is the normal response of ankle pressure to exercise testing? - ✔✔There should be no change if
normal.
, With severe lower extremity arterial occlusive disease, how will distal Doppler waveforms appear? -
✔✔Markedly dampened, possibly making interpretation difficult for distal segments.
What is the usual cuff pressure used in arterial volume recording? - ✔✔65 mmHg.
What would the CFA signal look like with aortoiliac occlusion? - ✔✔Low pitched and monophasic.
T or F- Diastolic flow reversal is always present in all abnormal limbs. - ✔✔False. It may be absent in
vasodialted limbs.
What is the most important reason Doppler evaluations should be performed with patient in a basal
state and warm temperature? - ✔✔The results are influenced by the patient's peripheral resistence.
Audible Doppler venous signals are usually low frequency and vary with respiration, where as normal
arterial signals in the arms and legs are __________________. - ✔✔Relatively high frequency with
pulsatile components and dont change with respiration.
When listening with CW Doppler over a stenotic lesion you will hear high frequency or low frequency
sound? - ✔✔High frequency.
A normal PORH (postocclusive reactive hyperemia) response is a major velocity increase of what percent
increase in mean velocity? - ✔✔>100%.
What are falsely elevated less frequently than tibial ankle pressures? - ✔✔Toe pressures.
How can a PTFE graft be identified during ultrasonographic imaging? - ✔✔A double line appearance of
the graft walls.
Velocities measured in a reversed saphenous vein bypass graft are usually ___________ proximally and
____________ distally. - ✔✔Higher, lower.
