Q

PROCEDURE Transthoracic Echocardiogram: The technician will also apply a ______ to
the transducer that improves the
conduction of sound waves.

A

Gel

21
Q

PROCEDURE Transthoracic Echocardiogram: The technician will move the
transducer _______ and _______over the
chest to record images of sound-
wave echoes from the heart.

A

back and forth

22
Q

Provides a single line of information at a
higher frame rate than can be obtained
by two-dimensional echocardiography.

A

M mode echocardiography

23
Q

This technique enhances accurate
determination of linear dimensions and
improves quantitation of chamber size
and wall thickness.

A

M mode echocardiography

24
Q

It is useful for measuring or viewing
heart structures, such as the heart’s
pumping chambers, the size of the heart
itself, and the thickness of the heart
walls

A

M mode echocardiography

25
Q

• It is used to measure and assess the flow
of blood through the heart’s chambers
and valves.

A

Doppler echocardiography

26
Q

It can also detect abnormal blood flow
within the heart.

A

Doppler echocardiography

27
Q

echocardiography allow for creation of anatomic
images of the heart

A

M mode and 2 dimensional echocardiography

28
Q

utilizes ultrasound to record blood flow within
the cardiovascular system.

A

Doppler echocardiography

29
Q

• An enhanced form of Doppler
echocardiography.

A

Color doppler

30
Q

Assesses blood flow based on changes in
the ultrasonographic signal due to the
movement of erythrocytes relative to
the transducer.

A

Color doppler

31
Q

This technique is used to “see” the actual
motion of the heart structures.

A

2 D echocardiography

32
Q

view appears cone-shaped
on the monitor, and the real-time motion
of the heart’s structures can be
observed.

A

2 D echocardiography

33
Q

Captures three-dimensional views of the
heart structures with greater detail than
2-D echo.

A

3 D echocardiography

34
Q

shows enhanced views of the
heart’s anatomy .

A

3 D echocardiography

35
Q

This is the most common type of
echocardiography.

A

TRANSTHORACIC ECHOCARDIOGRAM

36
Q

TRANSTHORACIC ECHOCARDIOGRAM A device called a _________ will be
placed on your chest over your heart.

A

Transducer

37
Q

is
painless and noninvasive.

A

TRANSTHORACIC ECHOCARDIOGRAM

38
Q

This test requires that the transducer be
inserted down the throat into the
esophagus.

A

TRANSESOPHAGEAL
ECHOCARDIOGRAM

39
Q

provides superior image quality,
particularly for posterior cardiac
structures which are nearer to the
esophagus and less well visualized on
transthoracic echocardiography.

A

TRANSESOPHAGEAL
ECHOCARDIOGRAM

40
Q

It is performed while the person
exercises on a treadmill or stationary
bicycle.

A

STRESS
ECHOCARDIOGRAM

41
Q

• To visualize the motion of the heart’s
walls and pumping action when the
heart is stressed.

A

STRESS
ECHOCARDIOGRAM

42
Q

• A form of echocardiography performed
during cardiac catheterization.

A

INTRAVASCULAR
ECHOCARDIOGRAM

43
Q

• It uses a transducer or probe to generate
sound waves and produce pictures of
the insides of blood vessels.

A

INTRAVASCULAR
ECHOCARDIOGRAM

44
Q

• It is used to provide detailed information
about the atherosclerosis .

A

INTRAVASCULAR
ECHOCARDIOGRAM

45
Q

• uses
sound waves to check the heart of your
developing baby.

A

FETAL
ECHOCARDIOGRAM

46
Q

• can help find heart defects
before birth. If a heart problem can be
found early, the more likely treatment
will work.

A

FETAL
ECHOCARDIOGRAM

47
Q

Who performs an
echo test? A technician called a_______________
performs your echo.

A

cardiac sonographer

48
Q

They’re trained in
performing echo tests and using the most
current technology.

A

cardiac sonographer

49
Q

cardiac sonographer They’re prepared to work in a variety of
settings including ___________ rooms and
_____________ labs.

A

hospital rooms and
