Cardiac Examination Flashcards
What does malar flush indicate?
Mitral stenosis
What is malar flush?
Plum-red discolouration of the cheeks
What 5 major clinical signs are you looking for during end of the bed inspection?
- Cyanosis
- SOB
- Pallor
- Malar flush
- Oedema
What cardiac condition would oedema indicate?
Congestive heart failure
What is pedal oedema?
Swelling of the limbs
What 3 signs in the hands are associated with infective endocarditis?
- Splinter haemorrhages
- Janeway lesions
- Osler nodes
What 5 major signs are you examining for during general inspection of the hands?
- Colour
- Tar staining
- Finger clubbing
- Xanthomata
- Arachnodactyly
Major cardiac differential diagnosis for pallor of hands?
Congestive heart failure
What are xanthomata?
Raised yellow cholesterol-rich deposits that are often noted on the palm, tendons of the wrist and elbow
What do xanthomata indicate?
Hyperlipidaemia
Most common cause of hyperlipidaemia?
Familial hypercholesterolaemia - this is a risk factor for cardiovascular disease
What are arachnodactyly?
‘Spider fingers’ - fingers and toes are abnormally long and slender, in comparison to the palm of the hand and arch of the foot
What condition is arachnodactyly a feature of?
Marfans syndrome
What 2 cardiac defects is Marfans associated with?
- Mitral/aortic valve prolapse
2. Aortic dissection
3 most common cardiac causes of finger clubbing?
- Congenital cyanotic heart disease
- Infective endocarditis
- Atrial myxoma (very rare)
How do you assess for finger clubbing?
- Ask the patient to place the nails of their index fingers back to back.
- In a healthy individual, you should be able to observe a small diamond-shaped window (known as Schamroth’s window)
- When finger clubbing develops, this window is lost.
Differences between Osler’s nodes and Janeway lesions?
Oslers:
- Tender
- Red/purple
- Slightly raised
- Often pale centre
- Found on fingers or toes
Janeway:
- Non-tender
- Found on thenar and hypothenar eminences
How do you assess patient’s temperature?
Place the dorsal aspect of your hand onto the patient’s to assess temperature
What condition is cool and clammy hands associated with?
Acute coronary syndrome
What differential diagnosis would cool hands indicate?
Poor peripheral perfusion (e.g. congestive cardiac failure, acute coronary syndrome)
How do you assess capillary refill time?
Apply five seconds of pressure to the distal phalanx of one of a patient’s fingers and then release.
In healthy individuals, what is the normal CRT?
<2 seconds
What is the next step needed if the CRT is >2 seconds?
Need to assess central capillary refill time
What does a CRT >2 seconds indicate?
Poor peripheral perfusion (e.g. hypovolaemia, congestive heart failure)
For irregular heart rhythms, how long should you measure the pulse for?
60 seconds
What type of resting heart rate is typically seen in athletic individuals?
Bradycardia
Most common cause of irregular heart rhythm?
Atrial fibrillation
What is radio-radial delay?
Radio-radial delay describes a loss of synchronicity between the radial pulse on each arm, resulting in the pulses occurring at different times.
3 most common causes of radio-radial delay?
- Subclavian artery stenosis (e.g. compression by a cervical rib)
- Aortic dissection
- Aortic coarctation
What is a collapsing pulse?
A forceful pulse that rapidly increases and subsequently collapses.
3 most common causes of a collapsing pulse?
- 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)
What normal physiological states can cause a collapsing pulse?
Fever
Pregnancy
What high output states can cause a collapsing pulse?
Anaemia
Arteriovenous fistula
Thyrotoxicosis
What condition is a slow rising pulse associated with?
Aortic stenosis
What condition is a bounding pulse associated with?
Aortic regurgitation
Co2 retention
What condition is a thready pulse associated with?
Intravascular hypovolaemia e.g. sepsis
What blood pressure is defined as hypertension if under 80 years old?
> /= 140/90 mmHg
What blood pressure is defined as hypertension if over 80 years old?
> /= 150/90 mmHg
What blood pressure is defined as hypotension?
< 90/60 mmHg
What is a ‘narrow pulse pressure’ defined as?
Less than 25 mmHg of difference between the systolic and diastolic blood pressure
3 major causes of a narrow pulse pressure?
- Aortic stenosis
- Congestive heart failure
- Cardiac tamponade
What is a ‘wide pulse pressure’ defined as?
More than 100 mmHg of difference between systolic and diastolic blood pressure
2 major causes of a wide pulse pressure?
- Aortic regurgitation
2. Aortic dissection
A difference of more than 20 mmHg difference in blood pressure between each arm is abnormal and may suggest which cardiac abnormality?
Aortic dissection
Where is the carotid pulse located?
Between the larynx and the anterior border of the sternocleidomastoid muscle.
