Understanding ventricular contractility is crucial for assessing heart health. Our easy-to-use calculator helps medical professionals and students quickly determine key cardiac metrics like Stroke Volume (SV) and Ejection Fraction (EF). Get rapid insights into the heart's pumping efficiency with this essential tool for cardiac assessment and monitoring.
Formula:
This calculator utilizes two key formulas to assess ventricular function:
- Stroke Volume (SV): The volume of blood pumped from the left ventricle per beat.
SV = EDV - ESV- Ejection Fraction (EF): The percentage of blood pumped out of the ventricle with each beat, a vital indicator of contractility.
EF = ((EDV - ESV) / EDV) × 100
Where:
- EDV: End-Diastolic Volume (mL) - Volume of blood in the ventricle at the end of diastole.
- ESV: End-Systolic Volume (mL) - Volume of blood remaining in the ventricle at the end of systole.
