1
Q

What are the steps of the basic physical exam for the CV system?

A
  • Auscultate along the LLSB with the diaphragm of the stethoscope at the end of exhalation with the patient sitting and leaning forward (for aortic regurgitation)
  • Inspect precordium and palpate for location and size of apical impulse and form heaves and thrills with patient in supine position.
  • Auscultate precorium in axilla, at apex, at lower left sternal border, at pulmonic area, and at aortic area with the diaphragm of the stethoscope with that patient in supine position
  • Auscultate at the apex with the bell of the stethoscope
  • Measure the CVP
  • Palpate carotids separately
  • Auscultate over the carotid arteries
  • Auscultate apex in LLD (Left Lateral Decubitus position for S3 and S4) with the bell

Q

What is an opening snap and where is it heard?

What does an opening snap indicate?

A

Early diastolic sound heard between apex and LLSB

Mitral stenosis

17
Q 
What do the following mumurs sound like?
Aortic Stenosis?
Mitral Regurgitation?
Aortic Regurgitation?
Mitral Stenosis?
A

o Aortic stenosis ==> diamond shaped intensity between S1 and S2, medium pitch harsh sound, radiates to neck, Decreased A2, ejection click, S4, delayed carotid upstroke, narrow pulse pressure
o Mitral Regurgitation ==> “Holosystolic” rectangle shaped intensity between S1 and S2, high pitch musical or blowing sound, radiates to axilla, decreased S1, S3 laterally displaced diffuse PMI
o Aortic regurgitation ==> decrescendo after S2
o Mitral stenosis ==> S2 then opening snap with trumpet-shaped intensity that ends at S1

18
Q

Where do Aortic and Pulmonic murmurs radiate to?

Where do Mitral and Tricuspid mumurs radiate to?

A
  • Listen for Aortic and Pulmonic in subclavian or carotid

* Listen for Mitral and Tricuspid in axilla

19
Q

What are the qualities of Acute Aortic Insufficiency?

A
  • Murmur is short, decrescendo, blowing
  • S1 and S2 are both soft
  • S3 and S4 are commonly heard as before, with the patient supine or in the left lateral decubitus position, listening over the apex with the bell
  • Listen over the left sternal border in the 3rd and 4th interspaces (tricuspid). Ask the patient to sit up, lean forward, exhale, and not take another breath. In this way, the murmur is easier to hear since you won’t be confused by the patient’s breath sounds
20
Q

What are the qualities of Chronic Aortic Insufficiency?

A
  • S3 is common
  • Aortic ejection sound may be present
  • between S2 and S1 Murmur is high pitched, blowing, and decrescendo along the left sternal border. It is heard best with the patient sitting up and leaning forward at end expiration (same as acute AI)
  • Severity of the murmur correlates with the DURATION of the murmur
  • Austin Flint murmur is common, which is a low-pitched diastolic rumble secondary to the regurgitant jet of blood across the aortic valve, causing early mitral valve closure
21
Q

What are physical exam findings in Aortic Insufficiency aka Regurgitation?

A 
Water hammer pulse
Increased pulse pressure
Pistol shot femoral pulse
Quincke’s pulse
DeMuesset’s sign
22
Q

What is Water Hammer Pulse?

What are the exam moves to detect it?

A

A PE sign of Aortic Regurgitation
Bounding pulse that collapses
Blood travels back into the left ventricle and there is a sudden collapse of radial pulse
Pt is supine, radial pulse is felt with arm by side. Finger pressure is increased till the pulse ceases.
Pt then holds shoulder and arm at right angle, and the radial pulse is felt again.

23
Q

What is Increased Pulse Pressure?

A

Difference btw systolic pressure and the diastolic pressure. Normal is defined as 50-60.
> 80 mmHg ==> Aortic Regurgitation/insufficiency

24
Q

What is Pistol Shot Femoral Pulse?

A

a short, loud, snapping sound with each pulse when auscultating the femoral, brachial, or radial artery
A sign of Aortic Insufficiency

25
Q

What is Quincke’s Pulse?

A

Visibly pulsating capillary refill in a slightly compressed fingernail bed
A sign of Aortic insufficiency

26
Q

What is DeMusset’s Sign?

A

bobbing of head with each heartbeat

A sign of Aortic Insufficiency

27
Q

What are the signs of Mitral Stenosis?

A

• S1 is loud, which is the hallmark of MS
• Murmur is difficult to hear, though heard best with the bell between the LLSB and apex with the
patient in left lateral decubitus position
• Opening snap is diagnostic of MS, which is heard after S2 at the apex with the diaphragm
• Severity of MS correlates with the TIMING of the opening snap—if OS is EARLIER murmur is more SEVERE—and with the DURATION of the diastolic rumble and not with the intensity of the murmur
• A loud P2 is heard if pulmonary hypertension is present
• Atrial fibrillation is commonly present if it is a longstanding diagnosis

28
Q

Extremity exam
Pitting edema
Peripheral cyanosis
Nail plate turns white with distal margin red-brown

A
  • Pitting edema ==> CHF, renal failure, cirrhosis (Rated +1 to +4)
  • Peripheral cyanosis ==> insufficient oxygen or rarely methemoglobin or sulfhemoglobin from drug use
  • Nail plate turns white with distal margin red-brown ==> (results from decreased vascularity) ==> CHF, LV disease, Cirrhosis or diabetes
29
Q

What are the parameters that suggest orthostatic blood pressure?

A

bp falls 20 mmHg

HR rises 10

30
Q

What is Pulses Paradoxus?

What is the diagnosis?

A

Fall in bp > 12 mmHg during inhale
“paradoxus” is that you can hear beat with stethoscope, but cannot feel radial pulse during inhale
This should be examined whenever JVP ↑
• Dx ==> pericardial tamponade, asthma or decompensated COPD, and rarely in other conditions.
