Definition of echocardiogram Correct Answer-An ultrasound of the
heart using an echo machine equipped with a range of probes, each
having a spectrum of frequencies
Echocardiograph other names: Correct Answer-echo, transthoracic echo
(TTE), cardiac doppler, cardiac ultrasound.
Echo can utilize? Correct Answer-m-mode, 2D echo, doppler
examination
What are the 3 types of echos/ Correct Answer-1D: m-mode ecg- used to
see just left side of heart.
2-D produces a broader moving picture of heart.
Doppler measures blood flowing through the arteries.
An echo can determine? Correct Answer-chamber size, thickness,
function, assess hemodynamics, fluid in pericardium, congenital heart
disease, blood clots, tumors.
Common reasons an echo is ordered (3) Correct Answer-assessment of
LV function, measure of ejection fraction, wall motion abnormalities.
WMA= Correct Answer-wall motion abnormalities
, Definitions:
hypokinesis-
akinesis-
dyskinesis- Correct Answer-LV contraction is diminished.
no contraction.
uncoordinated contraction.
Ejection fraction normal range Correct Answer-55-65%
2D echo is unable to visualize? Correct Answer-Blood flow, it is
presented as just black on display
Doppler ultrasonography overcomes what? Correct Answer-overcomes
visualization of blood flow
Doppler system determines? Correct Answer-The velocity of blood flow
by assessing the change in frequency of the ultrasound reflected from
moving red blood cells.
What is achieved by directing ultrasound at flow of blood and by
listening to changes in frequency? Correct Answer-Allows doppler echo
to determine direction and speed of blood flow.
Echocardiogram used what type of sound maves? Correct Answer-High
frequency sound waves.
