Q

Cardiovascular Examination

How do you Auscultate the four valves?

A
  • Palpate the carotid pulse to determine the first heart sound.

Auscultate through the valve areas using the diaphragm of the stethoscope whilst continuing to palpate the carotid pulse:

Mitral valve: 5th intercostal space in the midclavicular line.

Tricuspid valve: 4th or 5th intercostal space at the lower left sternal edge.

Pulmonary valve: 2nd intercostal space at the left sternal edge.

Aortic valve: 2nd intercostal space at the right sternal edge.

Repeat auscultation across the four valves with the bell of the stethoscope.

(I’ve done this backwards start aortic)

Q

Cardiovascular Examination

Why are we using Bell vs Diaphragm?

A

The bell of the stethoscope is more effective at detecting low-frequency sounds, including the mid-diastolic murmur of mitral stenosis.

The diaphragm of the stethoscope is more effective at detecting high-frequency sounds, including the ejection systolic murmur of aortic stenosis, the early diastolic murmur of aortic regurgitation and the pansystolic murmur of mitral regurgitation

Example Summary

A

Example summary

“Today I examined Mrs Smith, a 64-year-old female. On general inspection, the patient appeared comfortable at rest and there were no objects or medical equipment around the bed of relevance.”

“The hands had no peripheral stigmata of cardiovascular disease and were symmetrically warm, with a normal capillary refill time.”

“The pulse was regular and there was no radio-radial delay. On auscultation of the carotid arteries, there was no evidence of carotid bruits and on palpation, the carotid pulse had normal volume and character.”

“On inspection of the face, there were no stigmata of cardiovascular disease noted in the eyes or mouth and dentition was normal.”

“Assessment of the JVP did not reveal any abnormalities and the hepatojugular reflux test was negative.”

“Closer inspection of the chest did not reveal any scars or chest wall abnormalities. The apex beat was palpable in the 5th intercostal space, in the mid-clavicular line. No heaves or thrills were noted.”

“Auscultation of the praecordium revealed normal heart sounds, with no added sounds.”

“There was no evidence of peripheral oedema and lung fields were clear on auscultation.”

“In summary, these findings are consistent with a normal cardiovascular examination.”

“For completeness, I would like to perform the following further assessments and investigations.”

Q

Cardiovascular Examination

Further investigations to offer:

A
  • Measure blood pressure: to identify hypotension, hypertension or significant discrepancies between the two arms suggestive of aortic dissection.
  • Peripheral vascular examination: to identify peripheral vascular disease, which is common in patients with central cardiovascular pathology.
  • Record a 12-lead ECG: to look for evidence of arrhythmias or myocardial ischaemia.
  • Dipstick urine: to identify proteinuria or haematuria which can be associated with hypertension.
  • Bedside capillary blood glucose: to look for evidence of underlying diabetes mellitus, a significant risk factor for cardiovascular disease.
  • Perform fundoscopy: if there were concerns about malignant hypertension, fundoscopy would be performed to look for papilloedema.

Cardiovascular Examination

Capillary Refill time

A

Apply five seconds of pressure to the distal phalanx of one of a patient’s fingers and then release.
In healthy individuals, the initial pallor of the area you compressed should return to its normal colour in less than two seconds.
A CRT that is greater than two seconds suggests poor peripheral perfusion (e.g. hypovolaemia, congestive heart failure) and the need to assess central capillary refill time.

Q

Cardiovascular Examination

Assessing Heart Rate

A

You can calculate the heart rate in a number of ways, including measuring for 60 seconds, measuring for 30 seconds and multiplying by 2 or measuring for 15 seconds and multiplying by 4. The shorter the interval used, the higher the risk of obtaining an inaccurate result, so wherever possible, you should palpate for a full 60 seconds.

For irregular rhythms, you should measure the pulse for a full 60 seconds to improve accuracy.

36
Q

Cardiovascular Examination

Normal and Abnormal Heart Rates

A
  • In healthy adults, the pulse should be between 60-100 bpm.
  • A pulse <60 bpm is known as bradycardia and has a wide range of aetiologies (e.g. healthy athletic individuals, atrioventricular block, medications, sick sinus syndrome).
  • A pulse of >100 bpm is known as tachycardia and has a wide range of aetiologies (e.g. anxiety, supraventricular tachycardia, hypovolaemia, hyperthyroidism).
  • An irregular rhythm is most commonly caused by atrial fibrillation, but other causes include ectopic beats in healthy individuals and atrioventricular blocks.
37
Q

Cardiovascular Examination

Radio Radial Delay

A

**loss of synchronicity between the radial pulse on each arm, resulting in the pulses occurring at different times.
**

Palpate both radial pulses simultaneously.
In healthy individuals, the pulses should occur at the same time.
If the radial pulses are out of sync, this would be described as radio-radial delay.
Causes of radio-radial delay include:

Subclavian artery stenosis (e.g. compression by a cervical rib)
Aortic dissection
Aortic coarctation

38
Q

Cardiovascular Examination

What is a collapsing pulse?

A
  • is a forceful pulse that rapidly increases and subsequently collapses. It is also sometimes referred to as a ‘water hammer pulse’.
  • Ask the patient if they have any pain in their right shoulder, as you will need to move it briskly as part of the assessment for a collapsing pulse (if they do, this assessment should be avoided).
  • Palpate the radial pulse with your right hand wrapped around the patient’s wrist.
  • Palpate the brachial pulse (medial to the biceps brachii tendon) with your left hand, whilst also supporting the patient’s elbow.
  • Raise the patient’s arm above their head briskly.
  • Palpate for a collapsing pulse: As blood rapidly empties from the arm in diastole, you should be able to feel a tapping impulse through the muscle bulk of the arm. This is caused by the sudden retraction of the column of blood within the arm during diastole.
39
Q

Cardiovascular Examination

What are the causes of a collapsing pulse?

A

Normal physiological states (e.g. fever, pregnancy)
Cardiac lesions (e.g. aortic regurgitation, patent ductus arteriosus)
High output states (e.g. anaemia, arteriovenous fistula, thyrotoxicosis)

40
Q

Cardiovascular Examination

Auscultate the carotid artery

A

Prior to palpating the carotid artery, you need to auscultate the vessel to rule out the presence of a bruit. The presence of a bruit suggests underlying carotid stenosis, making palpation of the vessel potentially dangerous due to the risk of dislodging a carotid plaque and causing an ischaemic stroke.

Place the diaphragm of your stethoscope between the larynx and the anterior border of the sternocleidomastoid muscle over the carotid pulse and ask the patient to take a deep breath and then hold it whilst you listen.

Be aware that at this point in the examination, the presence of a ‘carotid bruit’ may, in fact, be a radiating cardiac murmur (e.g. aortic stenosis).

41
Q

Cardiovascular Examination

Palpate the carotid pulse

A

If no bruits were identified, proceed to carotid pulse palpation:

  1. Ensure the patient is positioned safely on the bed, as there is a risk of inducing reflex bradycardia when palpating the carotid artery (potentially causing a syncopal episode).
  2. Gently place your fingers between the larynx and the anterior border of the sternocleidomastoid muscle to locate the carotid pulse.
  3. Assess the character (e.g. slow-rising, thready) and volume of the pulse.
42
Q

Cardiovascular examination

JVP

A

provides an indirect measure of central venous pressure. the internal jugular vein (IJV) connects to the right atrium without any intervening valves, resulting in a continuous column of blood.

Position the patient in a semi-recumbent position (at 45°).

  1. Ask the patient to turn their head slightly to the left.
  2. Inspect for evidence of the IJV, running between the medial end of the clavicle and the ear lobe, under the medial aspect of the sternocleidomastoid (it may be visible between just above the clavicle between the sternal and clavicular heads of the sternocleidomastoid. The IJV has a double waveform pulsation, which helps to differentiate it from the pulsation of the external carotid artery.
  3. Measure the JVP by assessing the vertical distance between the sternal angle and the top of the pulsation point of the IJV (in healthy individuals, this should be no greater than 3 cm).
43
Q

Cardiovascular Examination

What causes a raised JVP

A

Right-sided heart failure: commonly caused by left-sided heart failure. Pulmonary hypertension is another cause of right-sided heart failure, often occurring due to chronic obstructive pulmonary disease or interstitial lung disease.
Tricuspid regurgitation: causes include infective endocarditis and rheumatic heart disease.
Constrictive pericarditis: often idiopathic, but rheumatoid arthritis and tuberculosis are also possible underlying causes.

44
Q

Cardiovascular Examination

Conjunctival pallor

Inspection

A

suggestive of underlying anaemia. Ask the patient to gently pull down their lower eyelid to allow you to inspect the conjunctiva.

45
Q

Cardiovascular Examination

Corneal arcus

Inspection

A

a hazy white, grey or blue opaque ring located in the peripheral cornea, typically occurring in patients over the age of 60. In older patients, the condition is considered benign, however, its presence in patients under the age of 50 suggests underlying hypercholesterolaemia.

46
