Heart Rate, Stroke Volume And Cardiac Output

Question 1

What is Stoke volume defined as?

Answer 1

The volume of blood ejected from the left ventricle per beat.

Question 2

What units are stoke volume measured in?

Answer 2

Ml/min

Question 3

What is heart rate defined as?

Answer 3

The number of times the heart beats per minute

Question 4

What are the units heart rate?

Answer 4

Bpm

Question 5

What is cardiac output defined as?

Answer 5

The volume of blood ejected from the left ventricle per minute

Question 6

What are the units for cardiac output?

Answer 6

(L/min)

Question 7

How do you calculate cardiac output?

Answer 7

Q = SV x HR
Cardiac output = stroke volume x heart rate

Question 8

For an untrained performer what is the expected values for heart rate, Stoke volume, and cardiac output for REST?

Answer 8

HR= 60-75
SV= 70 ml/beat
Q= 5 l/min

Question 9

For an untrained performer what is the expected values for heart rate, Stoke volume, and cardiac output for MAXIMAL?

Answer 9

HR= 220 - age
SV= 100-120 ml/beat
Q= 20-30 l/min

Question 10

For an trained performer what is the expected values for heart rate, Stoke volume, and cardiac output for REST?

Answer 10

HR=50
SV= 100ml/beat
Q= 5 L/min

Question 11

For an trained performer what is the expected values for heart rate, Stoke volume, and cardiac output for MAXIMAL?

Answer 11

HR= 220-AGE
SV= 160-200 ml/beat
Q= 30-40 l/min
