S4

Atrial contraction against stiff ventricles

9

When is S3 normal to hear?

Children

10

Athletes

11

What is the order of the phases of the cardiac cycle (7)?

Atrial Contraction
Isovolumetric Contraction
Rapid Ejection
Reduced Ejection
Isovolumetric Relaxation
Rapid Filling
Reduced Filling

12

Where is the aortic valve heard?

Right 2nd ICS near sternum

13

Where is the pulmonic valve heard?

Left 2nd ICS near sternum

14

Where is Erb's point?

Left 3rd ICS

15

Where is tricuspid valve heard?

Left 4th ICS near sternum

16

Where is mitral valve heard?

Left 5th ICS mid-clavicular line

17

Where is point of maximal impulse?

Left 5th ICS mid-clavicular line

18

Stenosis

Turbulent blood flow through a stiff/narrowed valve

19

Regurgitation

Turbulent blood flow in an opposite direction than normal

20

When are systolic murmurs heard?

During Ventricular systole
(atrial Diastole)

21

When are diastolic murmurs heard?

During Atrial systole
(ventricular Diastole)

22

Do murmurs always indicate there is a problem?

NO

23

When do murmurs become a problem?

When there are symptoms -- get an EKG

24

What 3 things do you note about a murmur?

Location
Timing
Shape

25

Crescendo

Grows louder

26

Decrescendo

Grows softer

27

Cresendo-Decrescendo

First gets louder then softer

28

Plateau murmur

Same intensity throughout

29

Continuous murmur

Begins in systole and continues through diastole but does NOT have to be uniform

30

Patient positioning to better hear aortic regurgitation?

Lean forward
