Assume that the left ventricle of a child's heart has an EDV=90mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is ________ mL/beat, and his HR is ________ bpm.

Question

Quizplus · Accepted Answer

Stroke Volume (SV) is calculated as the difference between End Diastolic Volume (EDV) and End Systolic Volume (ESV), which is 90mL - 60mL = 30mL. Heart Rate (HR) is calculated by dividing the Cardiac Output (CO) by the Stroke Volume (SV), which is 2400 mL/min / 30 mL/beat = 80 beats per minute (bpm).
