Question 1

atrial events

Answer 1

atrial systole=0.1sec
atrial diastole =0.7 sec

Question 2

ventricular events

Answer 2

ventricular systole =0.3sec
ventricular diastole = 0.5 sec

Question 3

subdivisions of ventricular systole and diastole

Answer 3

ventricular systole —-
isometric contractio. =0.05 sec
ejection period =0.22 sec

ventricular diastole —-
protodiastole =0.04
isometric relaxation =0.08
rapid filling = 0.11 sec
slow filling =0.11 sec
last rapid filling = 0.11 sec

total = 0.53 sec

Question 4

3.muscular factor 4 atrial factor
Lubb
015 sec

Question 5

s2 sound

Answer 5

it occurs during protodiastole and part of isometric relaxation
dubb
0.12 sec

Question 6

s3 sound

Answer 6

rapid ventricular filling
best heard in mitral area
0.1 sec
mitral area

Question 7

s4 sound

Answer 7

atrial contraction.
0.04 sec
just before the first sound late diastole

Question 8

classification of murmurs

Answer 8

1 systolic murmur —
incompetent of av valve
stenosis of semilunar valve
murmur due to anemia
septal defect
contraction of aorta

2.diastolic murmur –
incompetence of semilunar valve
stenosis of av valve

3continuous murmur—
patent ducts arteriosclerosis
