cardiology terminology

Question 1

akinesis

Answer 1

no wall motion

Question 2

dyskinesis

Answer 2

inconsistent wall motion

Question 3

hypokinesis

Answer 3

reduced wall motion

Question 4

cardiac regurgitation

Answer 4

a backward flow of blood through the heart valves. usually due with vuvular stenosis due to congenital malformation, rheumatic fever, and endocarditis

Question 5

IHSS

Answer 5

idiopathic hypertrophic subaortic stenosis
-> enlargement of the septum and left ventricle wall
-> reduced cardiac output, and symptoms include fatigue and SOB

Question 6

cardiac output

Answer 6

the amount of blood pumped out each ventricle in 1 minute

Question 7

formula calculate cardiac output

Answer 7

cardiac output = heart rate x stroke volume

Question 8

stroke volume

Answer 8

the volume of blood pumped out by a ventricle with each heart beat. normal volume 80-100ml

Question 9

ejection fraction

Answer 9

the fraction of the total ventricular filling volume that is ejected during each ventricular contraction

Question 10

what is normal EF of LV?

Answer 10

50-75%

Question 11

what is normal EF of RV

Answer 11

35-50%

Question 12

stroke volume formula

Answer 12

EDV-ESV

Question 13

ejection fraction formula

Answer 13

ED-ES / ED-bkg

Question 14

why background is important?

Answer 14

• much BKG result falsely elevated EF
• less BKG results falsely depressed EF

Question 15

what does non-invasive mean?

Answer 15

to access both right and left ventricular pump performance
