Cardiovascular Examination Flashcards
In what position should the patient and bed be in for a basic cardiovascular examination
The patient should be on the bed comfortably supported by a pillow with the bed/their chest at an angle of 45 degrees. (This may not be possible if the patient is too sick to sit up)
Briefly name the 15 steps as listed in the PCP handbook for the basic CV examination
- Prepare patient
- Hand hygiene
- General inspection
- Inspection of the hands
- Measurement of the radial pulse/radio-radial delay*
- Measurement of blood pressure (ideally in both arms)/brachial pulse assessment*
- Examination of the head and neck
- Examination of the jugular venous pulse/hepatojugular reflux*
- Examination f the carotid artery pulse
- Inspection of the chest
- Palpation of the chest (apex beat/heaves*/thrills*)
- Auscultation of the heart
- Examination of the posterior chest
- Examination of the lower limbs
- Complete the examination
During the general inspection, what are you looking for?
Patient’s general mental state
Alertness
Respiratory effort/SOB at rest*
Malar flush*
Apparent comfort of patient: does the patient look in pain*
Treatments or adjuncts: Use of supplemental O2, GTN spray*, medications*, mobility aid*
Missing limbs or digits*
Cachexia (cardiac cachexia)*
During inspection of the hands, what are you looking for? (11 signs listed)
Nicotine stains
Clubbing
Pale palmar creases
Splinter haemorrhages*
Dusky bluish discolouration*
Temperature*
Sweaty/clammy hands*
Janeway lesions*
Osler’s nodes*
Xanthomata*
Capillary refill*
What do you note when measuring radial pulse?
- Rate (60-100bpm is normal), rhythm (regular vs irregular)
- radio-radial delay*
- radio-femoral delay*
- collapsing pulse*
(The character and volume of pulse are better assessed from palpation of the brachial or carotid arteries)
During examination of the head and neck what clinical signs are you looking for and what do they indicate?
Conjunctival pallor - anaemia
Lips and tongue - central cyanosis
Corneal arcus* - hypercholesterolaemia
Xanthelasma* - hypercholesterolaemia
Angular stomatitis* - iron deficiency
High arched palate* - suggestive of marfans syndrome
Dental hygiene* - important if considering causes of infective endocarditis
Sclera* - icterus/jaundice
Mucosa - petechiae suggestive of infective endocarditis
Which type of lighting is best for examining the JVP?
Natural light where possible
Which JVP is conventionally inspected?
Right side; internal jugular
Is the head rotated to look for JVP? Why, why not?
No as it will tense the sternocleidomastoid muscle
Which jugular vein is best for examining the cardiac wave form? Why?
The internal jugular vein as it is in a straight line with the right atrium. The external jugular vein is usually easier to see but can be falsely elevated due to external pressure.
How is JVP measured?
The height is measured as the vertical distance between the sternal angle and the upper level of pulsation of the internal jugular vein
What is an abnormal JVP and what does it indicate?
A measurement greater than 3cm indicates raised pressure in the right side of the heart: fluid overload, right ventricular failure, tricuspid regurgitation
When examining the carotid arteries, why should you check for bruits first?
Checking for bruits allows you to ascertain whether there is a partial obstruction to the artery. If an obstruction present is due to atherosclerosis/plaque, it may dislodge and embolise to the brain
REMEMBER TO GO THROUGH EACH SIGN AND DEFINE THEM. EG WHAT IS A BRUIT
hi :)
Why might checking both carotid pulses at the same time be problematic?
Decreasing significant amounts of blood flow to the brain may cause LOC

What is cyanosis?
Cyanosis occurs when a person has 5 g/dL of unoxygenated hemoglobin in the arterial blood. Central cyanosis (cyanosis of the lips, mucous membranes, and tongue) occurs when arterial oxygen saturation falls below 85% in patients with normal hemoglobin levels.
In light-skinned patients, cyanosis presents as a dark bluish tint to the skin and mucous membranes (which reflects the bluish tint of unoxygenated hemoglobin). But in dark-skinned patients, cyanosis may present as gray or whitish (not bluish) skin around the mouth, and the conjunctivae may appear gray or bluish. In patients with yellowish skin, cyanosis may cause a grayish-greenish skin tone.
Sweaty/clammy hands are associated with what type of syndromes?
Acute coronary syndromes
What do cool peripheries suggest?
Poor cardiac output/hypovoleamia
What are Janeway lesions and what do they suggest?
Non-tender macular erythematous palm and sole pulp lesions that contain bacteria indicating bacterial endocarditis. Will last for weeks before healing completely.

The lesions on the skin will heal without leaving any scar.
They are less commonly seen now that effective treatments for infective endocarditis exist
What are Osler’s nodes and what do they suggest?
Tender/painful red nodules on finger pulps/thenar/hypothenar eminences indicating infective endocarditis

What is aortic coarctation?
A congenital heart defect which occurs in 7% of patients with congenital heart disease; male:female ratio, 2:1.
Aortic coarctation is characterised by narrowing of the aortic lumen, often distal to the origin of the left subclavian artery at the site of the aortic ductal attachment (the ligamentum arteriosum); extensive collateral arterial circulation develops though the internal thoracic, intercostal, subclavian and scapular arteries to supply the rest of the body in patients with AC.

When palpating carotid pulse, what are you assessing?
Character and volume of pulse. eg a slow rising character occurs in aortic stenosis
What is a positive hepatojugular reflux sign and what does it suggest?
A positive hepatojugular reflux sign occurs when pressure applied to the liver results in a rise in JVP that is sustained and equal to or greater than 4cm
This suggests right sided heart failure/tricuspid regurgitation
If applying pressure to the liver, the corressponding rise in JVP in healthy individuals should last for how long before falling?
No longer than 1-2 cardiac cycles
What is a corneal arcus/arcus senilis and what is it suggestive of?
A greyish-white ring (or part of a ring) opacity occurring in the periphery of the cornea, in middle and old age. It is due to a lipid infiltration of the corneal stroma. With age the condition progresses to form a complete ring.

What is pectus excavatum?
An abnormality of the chest in which the sternum (breastbone) sinks inward; sometimes called “funnel chest.”
A congenital malformation of the chest wall characterized by a funnel-shaped depression with its apex over the lower end of the sternum; it is caused by shortening of the central portion of the diaphragm, which pulls the sternum backward during inhalation, and by the growth of ribs.
Except in mild cases, it decreases the ability of the child to engage in sustained exercise. It also delays recovery from coughs and colds, reduces the ability to eat a full meal (so that most patients are underweight), and often produces a functional heart murmur. Noisy breathing may occur during sleep. A child may develop an emotional problem because of embarrassment over the deformity. It can be satisfactorily corrected by surgery
What is this sign?
Pectus excavatum
What sign is this?
Pectus excavatum
What is pectus carinatum?
An abnormality of the chest in which the sternum (breastbone) is pushed outward. It is sometimes called “pigeon breast.”
Pectus carinatum is a far less common (ratio, 1:3 to 1:13) chest wall deformity than pectus excavatum; it is more common in men (2–3:1). While it is generally asymptomatic, cardiorespiratory symptoms in the form of palpitations, dyspnea, and wheezing are not uncommon, may be accentuated during exercise and disappear after surgery. Bronchial and pulmonary symptoms of asthma and chronic bronchitis occur in 16.4% of the patients. Because the physical deformity can evoke ridicule from their peers, these patients are often introverted with low self-esteem and tend to avoid appearing in public venues or engaging in sports in which they may have to remove their shirts. Some degree of kyphosis is present in most patients
What is this sign?
Pectus carinatum
what is this sign?
Pectus carinatum
What may a visible forceful apex beat suggest?
Hypertension or ventricular hypertrophy
What is a parasternal heave?
A parasternal heave is a precordial impulse that may be felt palpated in patients with cardiac or respiratory disease. Precordial impulses are visible or palpable pulsations of the chest wall, which originate from the heart or the great vessels.
How is a parasternal heave detected and what may it indicate?
A parasternal heave is detected by placing the heel of the hand over the left parasternal region. In the presence of a heave the heel of the hand is lifted off the chest wall with each systole.
A parasternal heave is caused by:
right ventricular enlargement, or
rarely, severe left atrial enlargement which pushes the right ventricle forwards
What is a thrill and what may it indicate?
The vibration accompanying a cardiac or vascular murmur, detectible on palpation.
A fine vibration, felt by an examiner’s hand on a patient’s body over the site of an aneurysm or on the precordium, resulting from turmoil in the flow of blood and indicating the presence of an organic murmur of grade 4 or greater intensity. A thrill can also be felt over the carotids if a bruit is present and over an arteriovenous fistula in the patient undergoing hemodialysis
What is a bruit and what may it indicate?
an abnormal blowing or swishing sound or murmur heard while auscultating a carotid artery, the aorta, an organ, or a gland, such as the liver or thyroid, and resulting from blood flowing through a narrow or partially occluded artery. The specific character of the bruit, its location, and the time of its occurrence in a cycle of other sounds are all of diagnostic importance. Bruits are usually of low frequency and are heard best with the bell of a stethoscope.

What affet can fever have on heart rate?
Fever can increase HR.
When interpreting a tachycardia, allow 15-20 beats per minute for every degree above normal
What is a pulse deficit?
“Patients with atrial fibrillation or frequent ectopic beats may have a detectable pulse deficit. This means that the HR when counted by listening to the heart with the sethoscope is higher than the rate obtained when the radial pulse is counted at the wrist.
In these patients the heart sounds will be audible with every systole, but some early contractions preceded by short diastolic filling periods will not produce enough CO for a pulse ot be palpable at the wrist”
