8/13- Course Review Session 1 Flashcards
What is the differential diagnosis of “Lub Du-Dub”?
- Fixed splitting of S2 (A2-P2)
- S3 gallop (heard in decompensated heart failure)
- Opening snap: (mitral valve stenosis)
Besides S3 what are the (3) other early diastolic extra sounds?
T: tumor plop
- Extra sound that results from sudden “plopping” or “drooping” of a cardiac tumor (atrial myxoma) through the mitral valve
K: pericardial knock
- Extra sound that results from sudden “resistance” to ventricular filling by a thick calcified pericardium in constrictive pericarditis
OS: opening snap
- Results from sudden distension and bulging of the belly of MV leaflets (fused at their tips “commissures” in Rheumatic HD) in rheumatic mitral stenosis
**These are NOT S3 sounds/gallop
What are the physical findings in IHSS (HCM)?
- Spike-and-Dome or Bisferians arterial pulse
- Triple apical impulse
- Prominent palpable S4
What is a Bisferians arterial pulse/when does it occur?
- Bifid initial + wave early in systole
- Occurs before dicrotic notch
- Early LV ejection into aorta is hindered by the LV outflow obstruction; then LV overcomes it and more LV ejection occurs
What is heard in the dynamic auscultation of someone with IHSS (HCM)?
- Systolic murmur at apex/LSB
- Paradoxical A2-S2 split: late A2
- Louder and longer murmur with maneuvers that decrease EDV or increase systolic function
- Stand/Valsalva increases sound; squat decreases

All of the following are true except:
A. CO = SV x HR
B. EF of 65% is normal
C. EDV - ESV = SV
D. CI = CO/BSA
E. Vascular resistance = ratio of flow to pressure drop
All of the following are true except:
A. CO = SV x HR
B. EF of 65% is normal
C. EDV - ESV = SV
D. CI = CO/BSA
E. Vascular resistance = ratio of flow to pressure drop
VR = pressure difference/cardiac output
(SVR = [AO-RA]/CO)
- Flow (or CO) needs to be inversely proportional to vascular resistance
Normal EF is anything > 50% (normal range is 50-70%)

In a patient presenting with oppressive chest pain & ST elevation, you should:
A. Start an IV line first
B. Give aspirin to chew
C. Check BP then give SL NTG
D. If no change in pain and ST elevation with SL NTG, call Interventional Cardiologist
E. Check BP and HR then give metoprolol
F. All of the above
F
Start an IV line first- in case pt arrests so you can give life saving drugs
Give aspirin to chew- to reduce platelet aggregation
Check BP then give SL NTG- if BP is low (under 100) you should NOT give SL NTG
If no change in pain and ST elevation with SL NTG, call Interventional Cardiologist- now that you have excluded coronary spasm/Prinzmetal
Check BP and HR then give metoprolol- Metoprolol reduces HR and BP so you SHOULD avoid it if HR or BP are low
