How is stroke volume calculated from echocardiogram measurements?
AEDV added to the ESV
BESV divided by the EDV
CEDV minus the ESV
DEDV times the ESV
Answer & Solution
Correct answer: C. EDV minus the ESV
1. An echocardiogram records the end diastolic and end systolic volumes.
2. Stroke volume is their difference, EDV minus ESV.
3. A catheter can measure it too, but that is invasive and far more dangerous.
