Stroke Volume, VTI (Velocity Time Integral) & Cardiac Output
https://ecgwaves.com/topic/stroke-volume-vti-velocity-time-integral-cardiac-output/
WebStroke 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: Diameter of the aortic annulus: This measurement is made in the parasternal long-axis view during systole, when the diameter is greatest (usually halfway through systole).

WebSep 12, 2022 · CO = SV x HR. The definition of stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction. The average stroke volume of a 70 kg male is 70 mL Not all of the blood that fills the heart by the end of diastole (end-diastolic volume - EDV) can be ejected from the heart during systole.

WebThe cutoff values for the aforementioned “normal” and “abnormal” LVOT VTI are derived by understanding that only two variables influence SV in these calculations: LVOT VTI and LVOTd. Using an upper limit of 2.3 cm for the average LVOTd (1 SD above the mean19), any LVOT VTI of # 14 cm yields an SV of < 60 cc.

WebThe stroke volumes for each ventricle are generally equal, both being approximately 90 mL in a healthy 70-kg man. Stroke volume is an important determinant of cardiac output, which is the product of stroke volume and heart rate, and is also used to calculate ejection fraction, which is stroke volume divided by end-diastolic volume.
