What is the term for the volume of blood pumped out by each ventricle during a systolic contraction?
- Stroke volume (SV) (correct)
- Atrial contraction volume
- End-systolic volume (ESV)
- End-diastolic volume (EDV)
Which wave represents the atrial contraction in the cardiac cycle?
Which wave represents the atrial contraction in the cardiac cycle?
- c wave
- v wave
- x wave
- a wave (correct)
What is the formula to calculate stroke volume (SV)?
What is the formula to calculate stroke volume (SV)?
- SV = EDV - ESV (correct)
- SV = EDV + ESV
- SV = ESV - EDV
- SV = EDV / ESV
