echo quiz 3

cards for Monday's quiz (11/13/06)

itemnormal value
Neonatal transducer frequency: 7/7.5 MHz
Pediatric transducer frequency: 5MHz or higher
Adult transducer frequency: 2-4 MHz
Transesophageal echo (TEE) transducer frequency: 5 MHz
Doppler (aka Pedoff) transducer frequency: Continuous wave 2.0 MHz
4 media for recording data: VHS recorder Strip chart for M-mode (old) Printer (B/W, color) Digital images (new)
4 modes of echocardiography: • M-Mode • 2-D echo • Doppler • Color flow Doppler
normal aortic root size: 2.0—3.7 cm
normal aortic valve size: 1.5—2.6cm
normal left atrium size: 1.9—4.0cm
In M-mode of A/V valves, D point represents: end of ventricular systole
In M-mode of A/V valves, E point represents: end of rapid filling
In M-mode of A/V valves, F point represents: initial diastolic closure
In M-mode of A/V valves, A point represents: atrial systole (kick)
In M-mode of A/V valves, C point represents: end of ventricular diastole
Mitral M-mode E-F slope should measure: 70 mm
Mitral M-mode D-E excursion should measure: 20 mm
4 things M-mode LV level measurement will calculate: The ejection fraction Wall thickness Left ventricle size Right ventricle size
RVDd stands for: Right Ventricular Dimension - diastole
IVSd stands for: Interventricular septum - diastole
LVPWd stands for: Left ventricular posterior wall - diastole
LVDd stands for: Left Ventricular Dimension - diastole
LVIDs stands for: Left Ventricular Internal Dimension - systole
EF is calculated using the _________ method: Teicholz
Normal EF: 65% +/- 12
RVDd: 0.9 – 2.6 cm
IVSd 0.6 – 1.1 cm
LVDd 3.7 cm—5.6 cm
LVPWd 0.6 – 1.1 cm
LVIDs 2.0 – 3.8 cm
Formula used to calculate valve area (aortic): Continuity Equation
Formula used to calculate mitral valve area: Pressure half time -- MVA = 220/pressure half time

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
