Q

Jugular venous pressure (JVP)

A

Jugular veins reflect right atrial pressure

3-4 cm normal

Q

Carotid pulse

A

Auscultate listening for bruits. Then palpate upstroke. Don’t palpate both sides at the same time.
Brisk- normal
Delayed- suggest aortic stenosis
Bounding- suggest aortic insufficiency

Q

Palpate the chest wall

A

Finger pads- palpate for heaves and lifts from abnormal ventricular movements
Use ball of hand- palpate for thrills

Chest wall- aortic, pulmonic, left parasternal, and apical areas

Thrills- turbulence transmitted to chest wall surface by damaged heart valve ***** TQ!!!

Q

Assess Point of Maximal Impulse (PMI)

A

Tapping- normal
Sustained- suggest LV hypertrophy from HTN or aortic stenosis
Diffuse- suggest dilated ventricle from CHF or cardiomyopathy
Assess- location, amplitude, duration and diameter

17
Q

Bell

A

Best for detecting low pitched sounds like S3 and rumble of mitral stenosis

18
Q

Identify and describe murmurs - cause, timing, Dx, duration, pitch

A

Murmur: sounds from turbulent blood flow. Caused by stenosis or regurgitation of valves

Timing: are the murmurs systolic or diastolic?

Dx by palpating carotid upstroke (occur in systole) as you listen

Determine duration- early/mid/late systole or diastole

Pitch- high, medium or low pitched

19
Q

Murmur shape

A

Crescendo, decrescendo, or both (diamond shaped), or plateau (machinery)

Crescendo-decrescendo (both) murmur —> aortic stenosis

Plateau - holosystolic murmur of mitral regurgitation

20
Q

Murmur intensity

A

Grade 1: very faint, heard only after listener tuned in w/ stethoscope

Grade 2: quiet, heard immediately after placing stethoscope on chest

Grade 3: moderately loud

Grade 4: loud with palpable thrill

Grade 5: very loud with thrill, heard with stethoscope partly off chest

Grade 6: very loud with thrills heard without stethoscope

Grade 4-6 must have accompanying thrill ***** TQ!!!

21
Q

Ex. Harsh 2/6 medium-pitched holosystolic murmur heard at the apex describes

A

Mitral regurgitation

22
Q

Soft bowing 3/6 decrescendo diastolic murmur heard at lower left sternal border describes

A

Aortic regurgitation

23
Q

Midsystolic click

A

Mitral valve prolapse

24
Q

Main cause of PMI displacement

A

Pregnancy, cardiac enlargement, cardiomyopathy, ischemic heart disease

25
Q

Systolic murmur

A

Occur between S1 and S2. Associated with ventricular ejection. Coincide with carotid upstroke. May indicate valve disease

26
Q

Diastolic murmur

A

Occur between S2 and S1. Associated with ventricular relaxation and filling. Caused by aortic/pulmonic regurgitation or mitral/tricuspid stenosis

27
Q

Speeding of heart during inspiration

A

Sinus arrhythmia. Speeds up with inspiration, slows down with expiration. Heart sounds normal. S1 may vary with heart rate

28
Q

Splitting of S2 heart sounds ***** TQ!

A

Happens when RV filling time increases during inspiration. Increases RV ejection time. Causes delay of closing pulmonic valve. Hear both pulmonic and aortic closing separating, P2 and A2. During expiration, 2 sounds fuse into a single sound

Found at 2nd and 3rd ICS close to sternum

29
Q

Cause of S3

A

Hearing sound of rapid LV filling when mitral valve opens

Causes- common in children, young adults, pregnancy

Adults- indicate changes in ventricular compliance, decreased myocardial contractability, CHF, volume overload

30
Q

Cause of S4

A

Atrial contraction. Indicate decrease ventricular compliance. Left side caused by HTN, CAD, aortic stenosis. R side caused by pulmonary HTN or pulmonic stenosis

31
Q

Systolic murmurs

A

Between S1 and S2

Midsystolic - after S1 up to S2. Goes from soft to louder to softer. Caused by blood across semilunar valves ie aortic stenosis

Pansystolic- begin at S1, ends at S2. Occur with regurgitatant flow across M/T valve ** TQ!!

Late systolic, opening snap- mid to late systole, persists to S2. Caused by mitral valve stenosis/prolapse

32
Q

Diastolic murmurs

A

Occur after S2

Early- start after S2 (no gap). Fades before S3. Caused by regurgitant blood flow across semilunar valves ie Aortic regurgitation

Mid- after S2 (short gap). Fade before S1. Caused by turbulent flow across M/T valves

Late- starts late in diastole, continues to S1 (no gap)

33
Q

Functional Murmur

A

Short, early, midsystolic, decrease in intensity with actions that reduce LV volume. When standing, BP, SV, LV volume decrease. Squatting, opposite happens. Can identify prolapsed mitral valve, distinguish hypertrophic cardiomyopathy from aortic stenosis

Viscero-somatic reflexes: T1-T5 on left side

34
Q

Mitral valve prolapse

A

Mid to late systolic click
Opening snap

Caused by anxiety, panic attacks, coffee

Accentuate findings with valsalva maneuver

35
Q

PMI

A

5th interspace midclavicular line, 8 cm lateral to midsternal border

36
Q

Palpitations-

A

Palpitations- atrial fibrillation (irregularly irregular), paroxysmal supraventricular tachycardia (regular, rapid, sudden, offset), sinus tachycardia

37
Q

Dyspnea (SOB)

A

Dyspnea (SOB)- pulmonary embolus, spontaneous pneumothorax, anxiety

38
Q

Paroxysmal nocturnal dyspnea (SOB when sleeping)

A

Paroxysmal nocturnal dyspnea (SOB when sleeping). Left ventricular heart failure, mitral stenosis

39
Q

Edema

A

Edema (excessive fluid in interstitial tissue spaces)- renal and liver disease

40
Q

Dependent edema

A

Dependent edema- CHF, hypoalbuminemia

41
Q

Chest pain. Dx meaning-

A

Chest pain. Dx meaning- angina pectoris, MI, coronary heart disease, aortic aneurism
