Heart murmurs Flashcards
inspiration
increase intensity of right heart sound
expiration
increase intensity of left heart sound
hand grip
increase systemic vascular resistance
increase intensity of MR, AR, VSD, MVP murmurs
decrease intensity of AS, hypertrophic cardiomyopathy murmurs
valsalva
decrease venous return
increase intensity of MVP, hypertrophic cardiomyopathy
decrease intensity of most murmurs
rapid squatting (increase venous return, increase preload, increase afterload with prolonged squatting)
decrease intensity of MVP, hypertrophic cardiomyopathy
systolic heart sounds
aortic stenosis pulmonic stenosis mitral regurgitation tricuspid regurgitation VSD
Diastolic heart sounds
aortic regurgitation
pulmonic regurgitation
mitral stenosis
tricuspid stenosis
holosystolic, high-pitched “blowing murmur”
Mitral/ trisucpid regurgitation
mitral regurgitation is loudest at the ______
apex
MR is enhanced by ____ , _____ and ______
squatting
hand grip
expiration
often due to ischemic heart disease, mitral valve prolapse, LV dilation, infective endocarditis, rheumatic fever
TR is loudest at the _____
tricuspid area and radiates to right sternal border
TR is enhanced by ______
inspiration
can be caused by RV dilation, rheumatic fever, infective endocarditis
crescendo-decrescendo systolic ejection murmur following ejection click
Aortic stenosis
ejection click due to abrupt halting of valve leaflets… LV»_space; aortic pressure during systole
AS is best heart at _____
aortic area
often due to age-related calcific aortic stenosis or bicuspid aortic valve
pulses weak with a delayed peak
pulsus parvus et tardus
- seen in AS
