| Answer |
|
|
| What is the definition for "Efficiency of Contraction"? |
measured as Blood OUTPUT from LEFT Ventricle |
| What is the equation for Cardiac Output? |
Cardiac Output = HR x SV = Liters per Minute |
| What is the equation for Stroke Volume? |
Stroke Volume = EDV - ESV |
| What do EDV and ESV stand for? |
End-Diastolic-Volume & End-Systolic-Volume |
| What is EDV determined by? |
"Preload" - Ventricularfilling time (HR), Venous return |
| What is ESV determined by? |
FORCE of Contraction - Health of muscle, Intrinsic STRETCH of Ventricle (EDV), ANS (+/- circulating Hormones) |
| What is Stroke Volume? |
the amount of Blood OUT of the LEFT Ventricle every contraction |
| What is the Ejection Fraction? |
SV/EDV - normally between 50-75% |
