# What would be the heart rate of a person if the cardiac output is 5L, blood volume in the ventricls at the end of the diastole is 100mL and at the end of ventricular systole is 50mL?Option 1)50 beats per minuteOption 2)75 beats per minuteOption 3)100 beats per minuteOption 4)125 beats per minute

Cardiac Output -

The stroke volume multiplied by the heart rate (number of beats per min.) gives the cardiac output.

- wherein

The cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and averages 5000 mL or 5 litres in a healthy individual. The body has the ability to alter the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cardiac output of an athlete will be much higher than that of an ordinary man.

Cardiac output is the product of heart rate ( number of beats per minute) and te stroke volume.

Given

Cardiac output [CO] = 5L

Stroke volume [SV] = EDV - ESV = 100mL - 50mL = 50mL or 0.05L

Heart rate =  beats per minute

Option 1)

50 beats per minute

Option 2)

75 beats per minute

Option 3)

100 beats per minute

Option 4)

125 beats per minute
