Left Ventricle Function Measurement

The following M Mode left ventricle (LV) functions can be
measured.
1. LV End Diastolic Volume
2. LV End Systolic Volume
3. Stroke Volume
4. Ejection Fraction
5. Cardiac Output
LV End Diastolic Volume (EDV)
The EDV is the volume of the LV at the end of diastole. It
corresponds to the PR interval in ECG.
LV End Systolic Volume (ESV)
The ESV is the volume of the LV at the end of systole. It
corresponds to the T wave in ECG.
Two formulas are available for calculation of the LV
volumes.

Cubed formula

The cubed formula calculates the LV volume using the
equation:
The measurement that has to be given are LV internal
dimensions at systole (LVIDs) and at diastole (LVIDd).
