Question Answer
What is better for listening to high pitched sounds - the bell or the diaphragm?The diaphragm
What is better for listening to low pitched sounds - the bell or the diaphragm?The bell
What is better for listening to systolic murmurs, the bell or the diaphragm?The diaphragm
What is better for listening to aortic diastolic murmurs, the bell or the diaphragm?The diaphragm
What is better for listening to the murmur of mitral stenosis, the bell or the diaphragm?The bell
Where does the murmur of mitral regurgitation often radiate to?The axilla
Where does the murmur of aortic stenosis classically radiate to?The carotid arteries
What allows the murmur of mitral stenosis to be more audible?Rolling patient onto their left side
What allows the murmur of aortic regurgitation to be more audible?Patient sitting forward, breath held in expiration
Which heart sound is normally split on inspiration, especially in the young?S2
Do S3 and S4 occur in systole or diastole?diastole
Can S3 be benign?Yes
Can S4 be benign?No
What is S4 an indicator of?Decreased ventricular compliance (aortic stenosis, hypertrophied ventricle)
When is an ejection systolic murmur heard?Mainly in the middle of S1 and S2
What causes Ejection systolic murmurs?Aortic stenosis or pulmonary stenosis
What is meant by stenosis?Narrowing of a vessel - means blood can't flow out as well when it's supposed to
Where is aortic stenosis best heard?Aortic area, radiates to neck
Where is pulmonary stenosis best heard?Left Sternal edge, loudest on inspiration
When is a pansystolic murmur heard?As a constant sound between S1 and S2
What causes pansystolic murmurs?mitral regurgitation, tricuspid regurgitation, ventricular septal defect
What is meant by regurgitation?Valve opens backwards when it's not supposed to
Where is mitral regurgitation murmur best heard?Best heard at apex, radiates to axilla
Where is tricuspid regurgitation murmur best heard?left sternal edge (4th ICS presumably), no radiation
When is a mid-diastolic murmur heard?Sound in the middle of S2 and S1
What causes mid-diastolic murmurs?Mitral stenosis, tricuspid stenosis
Where can you best hear mitral stenosis?Apex, louder with exercise
Where can you best hear tricuspid stenosis?Left sternal edge (4th ICS), no radiation
When can you hear early diastolic murmurs?Just after S2
What are the causes of early diastolic murmurs?Aortic regurgitation, pulmonary regurgitation
What are the causes of continuous murmurs?patent ductus arteriosus, aortic stenosis and regurgitation together
What produces the heart sound S1?Closure of mitral and tricuspid valves at start of systole
What produces the heart sound S2?Closure of aortic and pulmonary valves at end of systole
What can inspiration do to S2?Split it
When is S3 heard?Early diastole, after S2
When is S4 heard?Late diastole, before S1
What causes S3?is common in young people and athletes, rapid ventricular filling, people with heart failure
What causes S4?Atrial contraction against stiff ventricle (poor ventricle compliance) - ventricular hypertrophy
