Right atrial pressure is evaluated by measurement of the:

IVC diameter and changes with sniffing

SVC diameter and changes with sniffing

Pulmonic valve regurgitation peak velocity

Normal right atrial pressure is:

When dividing the stroke volume by the ventricular end-diastolic volume, and multiplying by 100, what term is calculated?

Ejection fraction of the ventricle

Fractional shortening of the ventricle

Cardiac output

Simpson’s method is used to measure the:

Velocity of blood flow

Diameter of cardiac chamber

Volume of cardiac chamber

Apical 4 chamber view is used to measure:

Mitral valve surface area by planimetry

LVOT diameter

Right atrial surface area

LVOT diameter is measured at:

Mid-systole

End of diastole

End of systole

Right ventricle systolic function can be evaluated by measuring:

deceleration time of tricuspid valve E wave

Left atrial pressure

TAPSE

Pressure half time is the:

Half the time it takes the pressure gradient to become “0

Time it takes the pressure gradient to drop to half its maximal value

Time it takes the peak velocity to drop to half its maximal value

If (V) is the peak velocity, simplified Bernoulli equation states that:

Pressure gradient equals V²

pressure gradient equals 2V

Pressure gradient equals 4V²

What percentage of left ventricular filling occurs normally during the early ventricular relaxation?

20%

40%

80%

Which of the following can be measured at the end of T wave of ECG?

Diameter of left atrium

Diameter of aortic root

Aortic valve cusp separation

Which of the following terms refers to absent LV wall motion?

Akinesis

Hypokinesis

Dyskinesia

Which statement describes the relationship between the stroke volume, the heart rate, and the cardiac output?

Stroke volume = cardiac output x heart rate

Cardiac output = stroke volume x heart rate

Heart rate = stroke volume / cardiac output

Which method is used to measure aortic valve area in aortic stenosis?

dp/dt of mitral valve regurgitation

Continuity rule

severity of tricuspid valve regurgitation

Apical 3-chamber view is used to measure:

Doppler tracing of systolic LVOT flow

Doppler tracing of systolic RVOT flow

Doppler tracing of descending aorta flow

The flow Doppler of the right upper pulmonary vein is used to evaluate:

Right ventricular filling

Left ventricular filling

Left atrial filling

Which view is used to evaluate left ventricular filling by Doppler?

Short axis parasternal view

Suprasternal view

Apical 4-chamber view

The minimal ventricular volume is measured at the:

Beginning of “P” wave on ECG

beginning of “T” wave on ECG

End of ventricular systole
