WebWhat is cardiac output? Cardiac output is the volume of blood pumped from the left or right ventricle, per unit time. It is most commonly used to describe the left ventricular (LV) output to the systemic circulation, and is a product of the stroke volume and heart rate. Web3 jul. 2024 · Background Left ventricular outflow tract velocity time integral (LVOT VTI) is a measure of cardiac systolic function and cardiac output. Heart failure patients with low cardiac output are known to have poor cardiovascular outcomes. Thus, extremely low LVOT VTI may predict heart failure patients at highest risk for mortality. Methods Patients with …

WebThe Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism) represents the relationship between stroke volume and end diastolic volume.
