Exam 2 Heart sounds Flashcards
Atrioventricular valves include?
Mitral
Tricuspid
Semilunar valves include?
Aortic
Pulmonic
Bell used for what sound?
Diaphragm used for what sounds?
low pitched
high pitched
Auscultation sitting up/leaning forward best for what sounds?
soft murmurs at base
aortic or pulmonic regurg
Auscultation in left lateral recumbent position best for what sounds?
(on left side, left arm above head)
low pitched filling sounds (gallop/murmur) at apical impulse
S1 is?
Systole -> closure of mitral/tricuspid start of vent contraction
S2 is?
Diastole -> closure of aortic/pulmonic start of vent filling
S3 is?
Heard best where?
Early diastole -> vibration from rapid filling of vents
w/ bell at apex (low pitched)
S1 + S2 + S3 =?
Ventricular gallop
“KEN-tucky”
S4 is?
Heard best where?
Atria contraction at end of vent filling (atrial kick)
w/ bell at apex (low pitched)
S1 + S2 + S4 = ?
Atrial gallop
“Tenne-SEE”
Systolic murmur is?
Diastolic murmur is?
blood rushing thu leaky/narrow valve or wall b/w chambers during systole
same but during diastole
Thrill is?
Palpable murmur
U from vibration of loud murmur
Caused by stenosis or septal defect
Lift/Heave is?
Vigorous impulse felt thru chest wall
Caused by hypertrophy or hyper vent activity
Split S2 caused by?
Normal when?
Heard where?
A2 = aortic valve closes before pulmonic P2 = pulmonic valve closes before aortic
N during inspiration
Heard at 2nd/3rd L ICS
