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 |
