Pratt trained for the marathon for 8 months. Pratt’s resting heart rate is 40 beats/min and his blood pressure is 100/80. Pratt’s roommate Joline, watches a lot of TV and has resting heart rate of 90 beats/min and blood pressure of 140/85. Both have the same resting cardiac output of 5.0 liters/min. Determine the resting stroke volume and mean arterial pressure. Based on your findings, whose heart is beating more efficiently? Round your numbers to 0.00 places.

Solution

resting stroke volume=Cardiac output/Heart rate

Pratts resting stroke volume=5/40

SV=0.125

Mean arterial pressure=systolic blood pressure+2(diastolic pressure)/3

=100+2(80)/3

MAP=86.66

Joline resting stroke volume=5/90

SV=0.055

Mean arterial pressure=systolic pressure+2(diastolic pressure)/3

=140+2(85)/3

MAP=103.33

healthy individual resting heart rate is 60-80.

Pratt heart is beating more efficient
