Hemodynamics

Review Hemodynamic Waves and pressures

QuestionAnswer
Aortic insufficiency is indicated by a/an: wide pulse pressure
PCW= 12/43/20. You suspect: mitral regurgitation
AO= 180/50/93. You suspect: Aortic regurgitation
Why is the Diastole low in aortic regurgitation? The AO has a second room (LV) to deposit the blood
LV = 188/9/15. AO= 140/90/107. You suspect: Aortic stenosis
PCW= 36, LV edp = 18. What abnormality could cause such a gradient? mitral stenosis
A pullback gradient between LV apex and LV outflow tract suggests: HOCM
Large "a" waves in the LA waveform suggest: Mitral stenosis
In atrial fibrillation, which of the following cannot be measured? LV EDP, PCW, PA mean, RA a waves RA a waves
Which measurement best indicates right heart preload? PCW mean, PA diastolic, RA v waves, RV edp, RV mean pressure RV edp
Which of the following occurs in tricuspid stenosis? elevated RV systolic, Canon "v" waves, large "a" waves in the RA, elevated PA mean pressure, All of the above Large "a" waves in the RA
The square root sign in an RV waveform suggests Restrictive cardiomyopathy or constrictive pericarditis
In cardiac tamponade: Right heart pressures elevate and equalize
In pulmonary embolus: PA diastolic pressure exceeds PCW
In pulmonic stenosis: There is a systolic gradient from RV to PA
In acute VSD RV pressures elevate
PA= 64/38/47. What condition is consistent with this pressure? PULMONARY HYPERTENSION
SVC Sat _ 65%, RA = 66%, RV = 76%, PCW = 99% VSD
Stenosis of semilunar valves would be indicated by: a systolic gradient
Stenosis of atrioventricular valves would be indicated by: a diastolic gradient
A patient's pulmonary capillary wedge pressure shows a deep Y descent. All diastolic pressures were equal and show a plateau. What diagnosis do these pressure reading suggest? Constrictive pericarditis or restrictive cardiomyopathy

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.
