Exam 2 Flashcards
HEENT, CV, PV, Thorax and Lungs
Headache: concerning for what conditions
life-threatening secondary causes such as meningitis, subarachnoid hemorrhage or mass lesion
types of primary headaches
migraine, tension, cluster, chronic daily
types of secondary headaches
systemic or infectious causes such as meningitis, subarachnoid hemorrhage
signs of subarachnoid hemorrhage
thunderclap headaches that reach maximal intensity over several minutes and are preceded by a sentinel leak
Erb’s point
3rd ICS on the left sternal border, best heard in the left lateral recumbent position
Mitral area
Also apex of the heart, best auscultated on the 5th ICS, at MCL
S3 - other name, best heard
Best heard with bell of stethoscope in the mitral/apical area, in early diastole, with person in left lateral decubitus position When rapid filling ends and slow filling starts
A PHYSIOLOGIC S3 is common in young people (to age 35-40), last trimester of pregnancy, and athletes In older people, may be associated with volume overload
A PATHOLOGIC S3, or ventricular gallop, is abnormal in people over age 40 (high ventricular filling pressures and abrupt deceleration of inflow across the mitral valve at the end of rapid filling phase of diastole)
Causes include decreased myocardial contractility, HF and ventricular volume overload from aortic or mitral regurgitation, and left-to-right shunts.
KENTUCKY
S4 - other name, best heard
Atrial gallop
Occurs in late diastole, due to atrial contraction, right before S1, due to pressure overload
Heard in mitral/apical area, in left lateral recumbent position, with bell
May sometimes occur in people over 40 after exercise
However, almost always pathological including hypertensive heart disease, aortic stenosis, and ischemic and hypertrophic CMY.
TENNESSEE
S1 is louder than S2
At the apex (5th ICS at MCL)
S2 is louder than S1
At the base
Abnormal JVP
> 3 cm above the sternal angle or more than 8 cm in total distance above the right atrium
May correlate with both acute and chronic HF, and tricuspid stenosis, chronic pulmonary htn, SVC obstruction, cardiac tamponade and constrictive pericarditis.
Where JVP is best assessed
From pulsations in the RIJV, which is directly in line with the SVC and RA.
Physical activity recommendations
Aerobic: 150 minutes of moderate- intensity activity such as brisk walking, each week.
When to begin screening for cardiovascular risk factors
Age 20 for individual risk factors or “global” risk of CVD and for any family history of premature heart disease (age < 55 in first-degree male relatives and age < 65 in first-degree female relatives)
Atypical ACS symptoms in women
Particularly in age > 65, upper back, neck or jaw pain, SOB, PND, n/v, and fatigue
Carotid upstroke always occurs in…
systole immediately after S1 so sounds or murmurs coinciding with the upstroke are systolic, those that follow are diastolic
Grade 1 murmur
Very faint, heard only when listener is tuned in, may not be heard in all positions
Grade 2 murmur
Quiet, but heard immediately after placing the stethoscope on the chest
Grade 3 murmur
Moderately loud
Grade 4 murmur
Loud, with palpable thrill
Grade 5 murmur
Very loud, with thrill. May be heard when the stethoscope is partly off the chest
Grade 6 murmur
Very loud, with thrill. May be heard with stethoscope entirely off the chest
PMI best palpated…
when patient is in the left lateral decubitus position if not found in supine position, may help if s/he stops breathing while you check location, diameter, amplitude and duration
Lateral displacement toward the axillary line from ventricular dilatation is seen in HF, CMY and ischemic heart disease.
PMI diameter
< 3 cm or size of a quarter, occupies one interspace May feel larger in left decubitus position A diffuse PMI of > 3 cm may singal LV enlargement, > 4 cm LV overload 5 x more likely
PMI amplitude
- Brisk, tapping, diffuse or sustained?
- Normal: small in diameter and brisk and tapping
- Abnormal: one example - hyperkinetic high-amplitude impulse occurs in hyperthyroid, severe anemia, pressure overload of LV from HTN or AS, or volume overload of the LV from AR
PMI duration
- Normal: Lasts through 2/3 of systole or less
- Abnormal: example, sustained high-amplitude impulse may indicate LVH
Stethoscope DIAPHRAGM
better for picking up high-pitched sounds of S1 and S2, murmurs of aortic and mitral regurgitations and pericardial friction rubs
Stethoscope BELL
more sensitive to low-pitched sounds of S3 and S4 and the murmur of mitral stenosis
Auscultating for MITRAL STENOSIS
Pt in left lateral decubitus position, place bell of stethoscope lightly on the apical impulse (may also hear S3 and S4 and mitral murmurs)
Auscultating for AORTIC REGURGITATION
Pt sits up, leans forward, exhales completely and stop breathing after exhalation. Place diaphragm on the left sternal border and at the apex, pausing so that patient can breathe
Split S1
Delayed closure of the tricuspid valve, best heard in the lower left sternal border
Is not affected by respiratory cycle
Diastolic murmurs
usually represent valvular heart disease
Systolic murmurs
may correlate with valvular heart disease but can be physiologic flow murmurs arising from normal heart valves
Murmur of aortic stenosis radiates to
neck especially on the right side
Murmur in mitral regurgitation radiates to
left axilla
Murmur descriptors
- Timing: systolic, diastolic 2. Shape: Crescendo, descrescendo, crescendo-decrescendo, plateau 3. Location of maximal intensity 4. Radiation 5. Intensity (grades) 1-6, 4-6 require presence of thrill 6. Pitch: high, medium, low 7. Quality: blowing, harsh, rumbling, musical
Fully described murmur
medium-pitched, grade 2/6, blowing decrescendo diastolic murmur, best heard in the 4th left interspace, with radiation to the apex (aortic regurgitation)
Peripheral artery disease defined
as atherosclerotic disease distal to the aortic bifurcation, some guidelines also include the abdominal aorta
AAA symptoms
abdominal, flank, back pain, unusual constipation or distention, urinary retention, difficulty voiding or renal colic (an expanding hematoma may cause symptoms by compressing bowel, aortic branch arteries, or the ureters
Prevalence of AAA in first-degree relatives
15-28%
Risk factors for AAA
older age, male sex, smoking, family history Other potential RF: other vascular aneurysms, taller height, CAD, cerebrovascular disease, atherosclerosis, HTN and HLD
AAA screening
USPSTF (grade B rec): one-time u/s screening of men age 65-75 who have smoked > 100 cigarettes in their lifetime
Key components of Peripheral Arterial Exam
- measure BP in both arms 2. palpate carotid upstroke, auscultate for bruits 3. auscultate for aortic, renal and femoral bruits, palpate the aorta and assess its maximal diameter 4. Palpate the pulses of brachial, radial, ulnar, femoral, popliteal, DP, and PT arteries 5. Inspect ankles and feet for color, temp, skin integrity
Signs of heart failure in infants
tachypnea, tachycardia and hepatomegaly
Noncardiac Signs of cardiac disease in infants
- Poor feeding
- FTT
- Irritability
- Tachypnea
- Hepatomegaly
- Clubbing
- Poor overall appearance
- Weakness
- Fatigue
PAT or PSVT in infants
May be normal (tolerated) in utero and in younger infants Child may look healthy or pale with tachypnea HR sustained at 240 beats/minute Dysrhythmia in older children is likely to be true
Split S2 in neonates
Detected in silence or when baby asleep
Its detection eliminates many, but not all, of the more serious congenital cardiac defects
S3 - Third heart sounds in children
Represent rapid ventricular filling Normal in children Should be differentiated from third heart sound gallop (pathologic)
Fourth heart sounds in children
Not common Suggest HF
Benign murmurs in infants
Newborn - Closing Ductus - Transient, soft, ejection, systolic (Upper left sternal border) Newborn - 1 yr - peripheral pulmonary flow murmur - Soft, slightly ejectile, systolic (Upper left sternal border, radiating to lung fields and axillae)
