Cardiac Flashcards
S1
mitral and tricuspid closure
S2
aortic and pulmonic closure
S1 or S2 normal inspiration split
S2
aortic valve auscultation location
right sternal ICS 2
pulmonic valve auscultation location
left sternal ICS 2
tricuspid valve auscultation location
left sternal ICS 5
mitral valve auscultation location
MCL ICS 5
S1 loudest at
MCL ICS 5 (mitral)
left sternal ICS 5 (tricuspid)
S2 loudest at
left sternal ICS 2 (pulmonic)
right sternal ICS 2 (aortic)
gallop
low pitch diastolic extra heart sound S3 or S4
S3
early diastole in mitral area due to audible mitral valve opening
S4
later diastole in mitral area due to stiff ventricles
S3 pathological or normal?
pathological in heart failure
normal in athletic or pregnant people
S4 pathological or normal
pathological in children
normal in older people
click/snap
high pitched extra sound during diastolic or systolic
ejection click (EC)
immediantly after S1 (systolic)
audible A/P valve opening
non ejection click
between S1 and S2 (systolic)
indicative of mitral valve prolapse
opening snap/click
after S2- early diastolic
audible M/T opening
earlier and higher pitched than a gallop
systolic ejection murmur description
diamond shaped between S1 and S2 due to forceful flow across a valve
audible S1- nonholoistic
cause of systolic ejection murmur
aortic or pulmonic stenosis
systolic regurge murmur descriptoin
flat between S1 and S2 due to back flow
inaudible S1- holostic
cause of systolic regorge murmur
mitral or tricuspid regurgitataion
