|---|---|---|---|---|---|
| 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
🗑
