Cardiac Murmurs Flashcards
inspiration
↑ venous return
hand grip
↑ afterload
valsalva (phase 2), stand up
↓ preload
squatting
↑ venous return, ↑ preload, ↑ afterload
Aortic Stenosis
Systolic
crescendo-decresendo, ejection murmur
loudest: heart base
Sx: syncope, angina, dyspnea on exertion
Mitral Regurg
Holosystolic
high pitched, “blowing”
loudest: apex, radiates to axilla
often 2° ischemia, MVP, LV dilation
Aortic Regurg
Diastolic
decrescendo, high pitched, "blowing" Wide PP (head bobbing) loudest: pt sits up & leans forward
Mitral Stenosis
Diastolic
after opening snap
delayed rumbling mid-late diastolic murmur
Severity? less time between S2 & OS
-> LA dilation -> compression of recurrent laryngeal n. -> hoarsness
S3
after S2
rapid ventricular filling against a complaint (saggy) ventricle
“sloshes around”
dilated ventricle 2° AR, MR, or systolic/HFrEF
S4
before S1
atrial kick against a stiff ventricle
hypertrophy 2° diastolic/HFpEF
loud P2
↑ pulm artery pressure (Pulm HTN)
