cardiac performance

Question 1

What is the equation for cardiac performance?

Answer 1

Q(rate) = F(h) X SV(h)

Question 2

What does Q rate mean?

Answer 2

• cardiac output (mL/min)

Question 3

What does f(h) mean?

Answer 3

• heart rate (beats/min)
• frequency

Question 4

What does SV(h) mean

Answer 4

• stroke volume (mL/beat)
• volume ventricle expels during contraction

Question 5

What does chronotropic effects mean?

Answer 5

• changing heartrate over time

Question 6

What is a positive chronotropic effect?

Answer 6

• tachycardia

Question 7

What is a negative chronotropic effect?

Answer 7

• bradycardia

Question 8

What does inotropic effects mean?

Answer 8

• changing SV(h) force

Question 9

What does it mean when inotropic effects are positive?

Answer 9

• greater SV(h)

Question 10

What does it mean when inotropic effects are negative?

Answer 10

• lower SV(h)
