What would be the heart rate of a person if the cardiac output is 5 L, blood volume in the ventricles at the end of diastole is 100 mL and at the end of ventricular systole is 50 mL?NEET 2019 (All India)
Options:
Answer:
C
Solution:
CO = HR X (EDV-ESV) (Cardiac Output = Heart rate x stroke volume; stroke volume = End Diastole volume - End Systole volume);
We have, CO = 5 Liters,5000ml
EDV = 100ml
ESV =50 ml
Hence, CO = HR x (EDV - ESV)
HR = CO / (EDV - ESV)
HR = 5000 / (100-50)
= 5000 /50
HR = 100 bpm
