13

What do the following
abbreviations stand for:
VSD?
P649

Ventricular Septal Defect

14

Define the following terms:
Stroke volume (SV)
P649

mL of blood pumped per heartbeat
(SV = CO/HR)

15

Define the following terms:
Cardiac output (CO)
P649

Amount of blood pumped by the heart
each minute: heart rate x SV

16

Define the following terms:
Cardiac Index (CI)
P649

CO/BSA (body surface area)

17

Define the following terms:
Ejection fraction
P649

Percentage of blood pumped out of the
left ventricle: SV = end diastolic volume
(nl 55%–70%)

18

Define the following terms:
Compliance
P649

Change in volume/change in pressure

19

Define the following terms:
SVR
P649

Systemic Vascular Resistance 
= (MAP – CVP) / (CO x 80)

20

Define the following terms:
Preload
P649

Left ventricular end diastolic pressure or
volume

21

Define the following terms:
Afterload
P649

Arterial resistance the heart pumps
against

22

Define the following terms:
PVR
P649

Pulmonary Vascular Resistance =
PA(mean) – PCWP/CO x 80

23

Define the following terms:
MAP
P649

Mean Arterial Pressure = diastolic BP +
1/3 (systolic BP – diastolic BP)

24

What is a normal CO?
P649

4 to 8 L/minute

25

What is a normal CI?
P649

2.5 to 4 L/minute

26

What are the ways to
increase CO?
P650

Remember “MR. PAIR”:
1. Mechanical assistance (IABP, VAD)
2. Rate—Increase heart rate

3. Preload—Increase preload
4. Afterload—Decrease afterload
5. Inotropes—Increase contractility
6. Rhythm—Normal sinus

27

coronary blood flow take
place?
P650

During diastole (66%)

28

Name the three major
coronary arteries.
P650

1. Left Anterior Descending (LAD)
2. Circumflex
3. Right coronary

29

What are the three main
“cardiac electrolytes”?
P650

1. Calcium (inotropic)
2. Potassium (dysrhythmias)
3. Magnesium (dysrhythmias)

30

ACQUIRED HEART DISEASE
CORONARY ARTERY DISEASE (CAD)
What is it?
P650

Atherosclerotic occlusive lesions of the
coronary arteries; segmental nature
makes CABG possible
