Q

What is the sequence of events during echocardiogram?

A
  1. Gel is placed on chest

Q

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

Study These Flashcards
A

Cardiomyopathy

23
Q

Describe the condition involved in heart valve disease

Study These Flashcards
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?

Study These Flashcards
A
  • heart murmur
  • heart attack
  • unexplained chest pains
  • atherosclerosis
  • congenital heart disease/defect
  • pericarditis
  • rheumatic heart fever
  • cardiomyopathy
  • heart failure
  • heart valve disease
25
What are the 4 echo techniques?
1. 2D Cross sectional 2. M-mode 3. Doppler 4. Color doppler
26
This echo technique "see" the actual motion of the heart structures
2D Cross Sectional
27
This echo allows you to see actual image but moving objects cannot be seen
2D cross sectional
28
What are the features of M mode echo technique?
- 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
What does the paper for M mode contain?
pieozoelectric crystal
30
Red and yellow lines seen in the product observed in M mode indicates _________________
red for systole (contraction) and yellow for diastole (relaxation)
31
This echo technique can measure and assess the flow of blood through the heart's chambers and valves
Doppler
32
To whom did the doppler technique attributed to?
Christian Johann Doppler in 1842
33
This is the enhanced doppler
2D color doppler
34
TRUE OR FALSE: Colors observed in the 2D color doppler indicates disease
FALSE The different colors are designate the direction of blood flow
35
This is the most common type of method of echo
Transthoracic (TTE)
36
Where does the transducer placed on the patient on transthoracic method?
Across the chest/heart
37
TRUE OR FALSE: ECG is needed to monitor heart during echo
TRUE
38
What is applied before echo procedure either directly on Px or unto the transducer?
Lubricating gel
39
What is the swishing sound that can be heard during an echo procedure?
Sound of blood flow
40
This echo method requires anesthesia and sedative?
Transesophageal (TEE/TOE)
41
This echo technique is used if the doctor’s need a detailed view of the patient’s heart
Transesophageal (TEE/TOE)
42
What is the use of anethesia for Transesophageal (TEE/TOE)?
To eliminate gag reflex = avoid vomitting during test
43
In what form does the anesthesia for Transesophageal (TEE/TOE) used?
Gel or spray
44
TRUE OR FALSE: The transducer for Transesophageal (TEE/TOE) is bigger than used in TTE
FALSE
45
TRUE OR FALSE: Both TTE and TEE/TOE does not require fasting
FALSE Px should NPO 4hrs before test
46
TRUE OR FALSE: TEE/TOE is requested before TTE
FALSE TTE must be reviewed first
47
This echo method is used on expectant mothers
Fetal echocardiography
48
At what week of pregnancy is the echocardiography used for pregnant women?
sometime during weeks 18 to 22 of pregnancy
49
TRUE OR FALSE: BOTH gestational age and heart abnormality of the baby can be determined through fetal echocardioography
TRUE
50
The fetal echo is considered safe for unborn child/fetus because ____________________
it does not use x-ray therefore there's no radiation involved
51
This echo method can show multiple images from different angles
3D Echo
52
3D echo is used prior to ____________________
heart valve surgery as well as to diagnose heart problems in children
53
Which echo uses contrast agent in blood stream contracts in blood stream to provide better image of heart
Contrast echocardiogram
