1

What occupies most of the anterior cardiac surface?

RV

2

The inferior border of the RV lies below the junction of the:

Sternum and the xiphoid process

3

This is behind the RV and to the left, it forms the lateral margin of the heart.

LV

4

The LVs tapered inferior tip if often termed the:

Cardiac apex and this produces the apical impulse, identified during palpating of the precordium as the PMI

5

Where is PMI typically found:

5th inter coastal space at or just medial to the left midclavicular line.

6

A displaced PMI is seen in:

RVH such as in COPD, MI, or heart failure

7

Mitral and tricuspid valves are called:

Atrioventricular valves

8

The aortic and pulmonic valves are called:

Semilunar valves

9

Systole is:

Ventricular contraction- LV pressure 5-120

10

Diastole is:

A period of ventricular relaxation - ventricular pressure falls further to below 5mmhg

11

During systole the aortic valve is ___ and the mitral valve is ___.

Open

Closed to prevent backflow

12

During diastole the aortic valve is ___ and the mitral valve is ____ open.

Closed

Open

13

S1 is produced by:

Closure of the mitral valve (normal)

14

S2 is produced by:

Closure of the aortic valve (normal)

15

S3 and s4 are produced by:

Atrial contraction and are generally pathologic in adults (heart failure, MI)

16

Right sided cardiac events usually occur slightly ___ than those on the left.

Later

17

A split s2 is caused by:

Left sided closure of the aortic valve and right sided closure of the pulmonic valve

18

Where can you hear a split s2?

2nd-3rd intercostal space near sternum.

19

When will a split s2 happen?

During inspiration (right heart filling time is increased, which increases rv stroke volume and the duration of rv ejection compared with the LV)

20

Split S1 is the result of:

An earlier mitral and later tricuspid sound

21

M1 of a split S1 is heard best ___ while the T1 is best heard ____.

Cardiac Apex

LLSB

22

Splitting of S1 does or does not vary with respiration?

Does not

23

Distinct heart sounds distinguishable by their pitch and their longer duration and are attributed to turbulent blood flow.

Heart murmurs

24

Heart murmurs are usually:

Diagnostic or a valvular heart disease

25

This has an abnormally narrowed valvular orifice that obstructs blood flow:

Stenotic valve

26

When a valve allows blood to leak backward in a retrograde direction:

Regurgitate murmur

27

Murmurs in children may be innocent flow murmurs T/F?

True

28

Aortic valve can beat be heard:

Right 2nd intercostal space

29

Pulmonic valve can best be heard:

left 2nd-3rd interspaces close to the sternum

30

Tricuspid valve can beat be heard:

LLSB
