heart sounds

Question 1

diastole

Answer 1

ventricular relaxation

Question 2

2 phases of diastole

Answer 2

passive filling, active filling

Question 3

passive filling

Answer 3

just ventricular relaxation

Question 4

active filling

Answer 4

atrial contraction

Question 5

all valves open

Answer 5

passively

Question 6

moderator band

Answer 6

ensures coordinated contraction of all three papillary muscles in the right ventricle

Question 7

when does the heart itself perfuse?

Answer 7

during the diastolic phase of the cardiac cycle

Question 8

S1 Lub

Answer 8

closure of AV valves, louder, longer, lower

Question 9

S2 Dub

Answer 9

closure of semilunar valves, short, high pitched

Question 10

S3 lub-dub-ta

Answer 10

ventricular filling, disappears with age

Question 11

S4 ta-lub-dub

Answer 11

atrial contraction, rare

Question 12

sound in heart

Answer 12

carried in the direction of blood flow

Question 13

stenosis

Answer 13

normal direction of blood flow through narrowed orifice

Question 14

regurgitation

Answer 14

retrograde flow due to inadequate valve closure

Question 15

systolic murmurs

Answer 15

aortic stenosis and mitral regurgitation

Question 16

diastolic murmurs

Answer 16

aortic regurgitation (early) and mitral stenosis (late)

Question 17

aortic stenosis

Answer 17

louder of 2 systolic murmurs, heard in R 2nd intercostal space

Question 18

Answer 18

heard in left 3rd intercostal space

Question 19

aortic regurgitation

Answer 19

heard in left 3rd intercostal space

patent ductus arteriosus

Answer 21

continuous sound, heard in the left 2nd intercostal space
