Intro To Systolic Function

Question 1

Defined as excessive wall motion

Answer 1

Hyperkinesis

Question 2

Reduced motion/wall thickening

Answer 2

Hypokinesis

Question 3

No thickening

Answer 3

Akinesis

Question 4

The wall or segment is moving the opposite direction of normal

Answer 4

Dyskinesis

Question 5

> 40% wall thickening

Answer 5

Normal wall motion

Question 6

Which artery perfuse the basal and mid inferior wall?

Answer 6

RCA

Question 7

List the most to least accurate assessments of EF

Answer 7

1. 3D trace (a specialized thing)
2. Simpson’s biplane EF
3. Teicholz (parasternal EF)

Question 8

What is normal value for fractional shortening? How is it calculated?

Answer 8

25-47%
FS= LVIDd-LVIDs/LVIDd

Question 9

What is normal EF?

Answer 9

> /=55%

Question 10

When is end diastole on the ECG?

Answer 10

Onset of the QRS

Question 11

When is end systole on the ECG?

Answer 11

Near the end of the T wave

Question 12

The inability of the LV to contract properly

Answer 12

Systolic dysfunction

Question 13

What is the most common cause of systolic dysfunction?

Answer 13

Coronary arterial disease

Question 14

Why can systolic dysfunction cause congestive heart failure?

Answer 14

Because there is a back of blood due to the heart not being able to pump high volumes of blood out and the back up causes the chambers to dilate

Question 15

What is normal TAPSE?

Answer 15

> /= 1.7

Question 16

How can we assess RV systolic function using TDI?

Answer 16

Measure the s prime wave.
Should be >9.5cm/s

Question 17

What is another way (more advanced) to assess LV systolic function?

Answer 17

2D strain
