lung and heart ausculation Flashcards
what does the S1 sound represent
closing of mitral and tricuspid valves
what does S2 sound represent
closing of aortic and pulmonic valves
if we are exercises and the systolic does not go up what does that indicate
HF
what is the S3 heart sound an indicator of
rapid ventricular filling at early diastole due to excess volume in the atria ,
sign of HF
S3 heart sound is normal in what type of people
children , adolescents , prego, and athletes
what hurt sound is due to exaggerated
atrial kick forcing blood into a stiff ventricle
S4
S4 heart sound is a sign of what
HTN
disastolic HF
acute myocardial ischemia
is S4 ever normal?
no always pathological
what are abnormal heart sounds that are due to the turbulent blood flow through stenotic heart valves or regurgitant blood flow through incompetent valves.
heart murmurs
what is narrowing or constriction of that prevents heart valve from opening fully; may results from growth, abnormal calcified deposit
stenosis
what occurs when a heart valve closes improperly and
blood move back into a heart chamber
insufficiency (regurgitation)
what occurs when enlarged valve leaflets in the mitral valve bulge backward into the left atrium during ventricular systole
prolapse
during a vesicular lung sound inspiratory sound last ___ then expiratory sound
longer
during broncho- vesicular lung sound inspiratory and expiratory are
the same
during bronchial lung sound the expiratory sound last ___ then inspiratory ones
longer
