ECG110 Exam #1 Review

Calculate the RVSP using these values: IVC 2.3 & collapses >50%, TR Vmax 2.8. Remember to include units.

What does the mosaic "blue" flow represent in this image?

• TR

• AI

• PI

• MR

What part of the cardiac cycle does the E-wave correspond to on the MV spectral Doppler?

• A. atrial contraction

• B. rapid early filling

• C. diastasis

• D. both B & C

When acquiring LAVi measurements, which of the following would be considered a normal LAVi?

(a)  

• 25 mL/m 2
• 26

• 35 mL/m2

• 48 mL

What is the normal IVC diameter?

• 1.5-2.0 cm

• 2.0-3.0 cm

• less than 2.0 cm

• 1.2-2.1 cm

Tissue Doppler Imaging...

• measures the velocity of the myocardial movement as it passes through the sample gate toward the PWD cursor.

• is a mirror image of the MV inflow waveform

• is used to calculate E/e'

• all of the above

As a person ages, their E wave is expected to (a)   , while the A wave is expected to (b)   .

• increase
• decrease
• stay the same
• reverse

The septal annulus e' measurements from MV TDI can sometimes be contraindicated. Select 3 examples of contraindications.

• Abnormal EF

• Hypertrophic Cardiomyopathy

• MAC

• Body Habitus

• Prosthetic valves

If a patient is suspect for Pseudonormal, Grade II diastolic dysfunction, the sonographer should repeat the MV Inflow PW Doppler with the Valsalva Maneuver. If the patient has truly normal filling patterns & diastolic function, what will happen to the MV Inflow waveform pattern?

• It will stay the same --Big E, Little A

• It will reverse -- Little E, Big A

• It will equalize -- E & A will be the same size

• It will disappear -- E & A will flatline

What type of Doppler is shown in this spectral Doppler tracing?

• Pedoff

• High PRF

• PW

• CW
