Cardiology Flashcards
used for Mid to high pitched sounds
* Mitral Regurgitation
* Aortic Stenosis
Diaphragm
used for low tones such as S3, S4
Bell
Closure of the mitral and tricuspid valve (AV
valves).
* Best heard 5th intercostal space, L side.
S1 (systole) ”lub”
Closure of the aortic and pulmonic valves
(semilunar valves).
* Best heard 2nd intercostal space, L side.
* Normal during inspiration, abnormal if heard
on expiration.
S2 (diastole) “dub”
Fluid overload: CHF, pregnancy.
* Normal: children, athletes, pregnancy.
* Best heard 5th intercostal space, L side
S3
Stiff L ventricle: LVH.
* Normal: elderly due to atherosclerotic vessels.
* Best heard 5th intercostal space, L side.
S4
Cause: failure of the heart’s function as a pump.
* Symptoms: acute or gradual dyspnea, fatigue, dry cough, lower extremity
edema, pulmonary edema, ascites. S3 sound. SOB worse with exercise or
while laying dow
CHF
Left-sided failure: blood backs up into the lungs (L for LUNGS).
Right-sided failure: lower extremity edema, jugular venous distention
Risk factors: coronary artery disease, hx MI, HTN, DM, heart valve disease.
* Treatment: stop smoking, physical exercise, limit NA, diuretics, BP meds.
Cause: bacterial infection of the heart lining/valves.
* Symptoms: fever, chills, malaise, new murmur, splinter hemorrhages on nail
beds, petechia on palate.
* Osler nodes: tender, purple-pink nodules found on distal fingers/toes.
* Janeway lesions: irregular, non-tender, erythematous macules or papules on hands and soles.
* Risk factors: older age, artificial valves, IV use, poor dental hygiene.
* Treatment: antibiotics, surgery.
Ineffective Endocarditis (IE)
irregular, non-tender, erythematous macules or papules on hands and soles.
Janeway lesions- assc. with infective endocarditis
tender, purple-pink nodules found on distal fingers/toes.
osler nodes- assc. with ineffective endocarditis
- Prophylaxis tx before dental procedure for eneffective endocarditis
Amox 2g (adult), 50mg/kg (children)
A bulge or swelling in the aorta. Dissecting: tear in the inner layer of
the aorta.
* Cause: tear in the inner layer of the aorta.
* Symptoms: AAA can be asymptomatic. With a tear: sudden onset of
severe, sharp, excruciating pain on abdomen, flank, or back, hypotension, abdominal distension.
* Risk factors: older age, smokers, HTN.
* Treatment: surgery, meds.
Dissecting Abdominal Aortic Aneurysm (AAA)
- Cause: abnormal heart rhythm. Short circuit in the heart causes atria to pump rapidly. Can cause clot to form, leading to stroke or death.
- Symptoms: sudden SOB, fatigue, angina, palpitations, lightheadedness, syncope,
fluid retention. Pulse >110bpm with hypotension. - Risk factors: HTN, CAD, ACS, caffeine, nicotine, alcoholism, heart failure, LVH, PE,
COPD, sleep apnea. - Treatment: BB (metoprolol), CCB (diltiazem), digoxin, warfarin.
- Patient education: avoid stimulants (caffeine, nicotine, decongestants).
Atrial Flutter/Atrial Fibrillation
Atrial Fibrillation INR goal
what if Synthetic/Prosthetic Valves?
INR 2-3
Synthetic/Prosthetic Valves= INR 2.5-3.5
