Cardiac OSCE Flashcards
What is pulsus alternans?
alternating strong and weak pulse palpable at radial or femoral arteries
What causes a water hammer pulse?
Due to large stroke volume and backflow of blood from the aorta into LV
*indicative of aortic regurgitation.
What can a paradoxical pulse be used for?
to assess pericarditis or tamponade when there is varied pulse strength/amplitude with respiration
What is Kussmaul’s sign?
- Normal JVP shows decline in inspiration but the a wave amplitude increases
- If there is an increase in JVP, or even no change in JVP on inspiration, this is a positive Kussmaul’s and may indicate impaired venous return to the right heart.
When might you see a hyperkinetic high amp impulse?
- hyperthyroidism
- severe anemia
- pressure overload of LV from HTN or aortic stenosis
- volume overload of LV from AR
Aortic Stenosis
- Harsh quality
- RIGHT 2nd ICS/3rd ICS
- Radiates to suprasternal notch and carotids
- Delayed pulses (pulsus tardus et parvus)
Mitral Regurgitation
- Blowing quality, holosystolic
- Prominent at apex, radiates to LEFT axilla
- Loudness correlates with degree of valve insufficiency
Pulmonary Stenosis
- Harsh, loud, ejection click
- LEFT 2nd ICS/3rd ICS
- Radiates to the LEFT shoulder
- Increases with inspiration
Tricuspid Insufficiency
- Blowing quality, increases with inspiration
- Holosystolic
- Lower LEFT sternal border
Aortic Regurgitation
- Blowing, decrescendo murmur
- LEFT 2nd ICS to the 4th ICS
- Auscultate with diaphragm
Mitral Stenosis
- Rumbling, low pitched
- Best heard at apex
- Auscultate with bell
Pulmonary Insufficiency
- Blowing quality
Tricuspid Stenosis
- Increases in intensity with inspiration
- Decreases in intensity with expiration and valsalva
What are the following special tests used for?
- Left lateral decubitus
- Sitting and leaning forward
- Straining/valsalva
- JVP
- Patient on left side with left arm above head; Palpate PMI and auscultate for systolic murmurs; Increases chance of hearing mitral stenosis and extra heart sounds
- Increases chance of hearing aortic regurgitation
- Increases chance of hearing mitral regurgitation
- Hepatojugular reflex
What does valsavla help with?
differentiate between aortic and mitral prolapse or HCM
What is hepatojulular reflex used for?
adjunct to measuring JVP
How can you differentiate between aortic stenosis and MVP?
sitting and squatting test
