A novel quantitative indicator of the left ventricular contraction based on volume changes of the left ventricular myocardial segments
Mersedeh Karvandi, Saeed Ranjbar
Ejection fraction (EF) is commonly measured by echocardiography, by dividing the volume ejected by the heart (stroke volume) by the volume of the filled heart (end-diastolic volume…

Mathematical modeling applied to the left ventricle of heart
Saeed Ranjbar, Mersedeh Karvandi
Background: How can mathematics help us to understand the mechanism of the cardiac motion? The best known approach is to take a mathematical model of the fibered structure, insert…
