Question

What will be the number of heartbeats per minute,
if the stroke volume of heart increases, with total
volume of heart increases, with total volume of
blood remains same?
(a) Remains constant (b) Decreases
(c) Increases
(d) Becomes erratic​

Answer 1

Answer:

Given this stroke volume and a normal heart rate of 70 beats per minute, cardiac output is 5.25 L/min. When heart rate or stroke volume increases, cardiac output is likely to increase also. Conversely, a decrease in heart rate or stroke volume can decrease cardiac output.

Answer 2

Answer:

Decreases

As the strock is increasing so it will pump blood faster and will decrease
