Q

What is the sequence of events during echocardiogram?

A
  1. Gel is placed on chest
  2. Transducer sends sound waves through chest to heart
  3. sound waves bounce back from heart to transducer
  4. computer processes sound-waves to make visual of beating heart.

22
Q

This is the condition wherein there is enlargement of heart due to thick/weakened heart muscle observe through echo

A

Cardiomyopathy

23
Q

Describe the condition involved in heart valve disease

A

there is an abnormality of blood flow of heart —> thin valves = prevent blood from flowing through the heart, to the lungs = become leaky = leak backwards = regurgitation

24
Q

What are the conditions detected through an echo?

A
  • heart murmur
  • heart attack
  • unexplained chest pains
  • atherosclerosis
  • congenital heart disease/defect
  • pericarditis
  • rheumatic heart fever
  • cardiomyopathy
  • heart failure
  • heart valve disease
25
Q

What are the 4 echo techniques?

A
  1. 2D Cross sectional
  2. M-mode
  3. Doppler
  4. Color doppler
26
Q

This echo technique “see” the actual motion of the heart structures

A

2D Cross Sectional

27
Q

This echo allows you to see actual image but moving objects cannot be seen

A

2D cross sectional

28
Q

What are the features of M mode echo technique?

A
  • Time motion display
  • image similar to a tracing than an actual picture of heart structure
  • has single ultrasound beam which displayed overtime on a moving sheet of paper
  • observes pumping chambers, size of heart, thickness of heart walls
29
Q

What does the paper for M mode contain?

A

pieozoelectric crystal

30
Q

Red and yellow lines seen in the product observed in M mode indicates _________________

A

red for systole (contraction) and yellow for diastole (relaxation)

31
Q

This echo technique can measure and assess the flow of blood through the heart’s chambers and valves

32
Q

To whom did the doppler technique attributed to?

A

Christian Johann Doppler in 1842

33
Q

This is the enhanced doppler

A

2D color doppler

34
Q

TRUE OR FALSE:

Colors observed in the 2D color doppler indicates disease

A

FALSE

The different colors are designate the direction of blood flow

35
Q

This is the most common type of method of echo

A

Transthoracic (TTE)

36
Q

Where does the transducer placed on the patient on transthoracic method?

A

Across the chest/heart

37
Q

TRUE OR FALSE:

ECG is needed to monitor heart during echo

38
Q

What is applied before echo procedure either directly on Px or unto the transducer?

A

Lubricating gel

39
Q

What is the swishing sound that can be heard during an echo procedure?

A

Sound of blood flow

40
Q

This echo method requires anesthesia and sedative?

A

Transesophageal (TEE/TOE)

41
Q

This echo technique is used if the doctor’s need a detailed view of the patient’s heart

A

Transesophageal (TEE/TOE)

42
Q

What is the use of anethesia for Transesophageal (TEE/TOE)?

A

To eliminate gag reflex = avoid vomitting during test

43
Q

In what form does the anesthesia for Transesophageal (TEE/TOE) used?

A

Gel or spray

44
Q

TRUE OR FALSE:

The transducer for Transesophageal (TEE/TOE) is bigger than used in TTE

45
Q

TRUE OR FALSE:

Both TTE and TEE/TOE does not require fasting

A

FALSE

Px should NPO 4hrs before test

46
Q

TRUE OR FALSE:

TEE/TOE is requested before TTE

A

FALSE

TTE must be reviewed first

47
Q

This echo method is used on expectant mothers

A

Fetal echocardiography

48
Q

At what week of pregnancy is the echocardiography used for pregnant women?

A

sometime during weeks 18 to 22 of pregnancy

49
Q

TRUE OR FALSE:

BOTH gestational age and heart abnormality of the baby can be determined through fetal echocardioography

50
Q

The fetal echo is considered safe for unborn child/fetus because ____________________

A

it does not use x-ray therefore there’s no radiation involved

51
Q

This echo method can show multiple images from different angles

52
Q

3D echo is used prior to ____________________

A

heart valve surgery as well as to diagnose heart problems in children

53
Q

Which echo uses contrast agent in blood stream contracts in blood stream to provide better image of heart

A

Contrast echocardiogram
