How to calculate the stroke volume index. You can also use this stroke volume calculator to find the stroke volume index, normalized with respect to the BSA (check the body surface area calculator). This way, you can easily compare your result with someone who has a different body type.
This stroke volume calculator estimates SV based on Doppler VTI determinations such as LVOT or on cardiac output.
The Fick Formula calculates cardiac output, cardiac index, and stroke volume.
The computation of left ventricular ejection fraction (LVEF) involves dividing the stroke volume by the end-diastolic volume (EDV) and is considered a central component in assessing both systolic and diastolic heart failure.
Stroke volume is defined as the amount of blood pumped by the heart per beat. The stroke volume formula is as the following: SV=EDV-ESV. Other equations like CO=HR x SV can calculate it. Stroke volume is affected by many factors like preload, afterload, contractility, and heart rate.
Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and subtracting the volume of the blood in the ventricle at the end of a beat (called end-systolic volume [note 1]) from the volume of blood just prior to the beat (called end-diastolic volume).
Stroke volume is the amount of blood ejected into the aorta during systole. Stroke volume is calculated by measuring the Doppler flow in the aortic valve. In the left ventricular outflow tract (LVOT), the following two measurements are performed:
