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
