- Myocardial Mechanics: Structure and Function of Myocardial FibersStructure and contractile function of myocardial fibers The left ventricular wall can be subdivided into several layers. These layers are similar to those seen in arteries…
- Ventricular Pressure-Volume Relationship: Preload, Afterload, Stroke Volume, Wall Stress & Frank-Starling’s lawVentricular Pressure-Volume Relationship Left ventricular pressure-volume relationship can be described by a loop diagram with volume depicted on the x-axis and left ventricular…
- Assessing left ventricular systolic functionMethods for assessing systolic function (contractile function) Several echocardiographic measurements are available to assess left ventricular systolic function. These methods…
- Left ventricular mass and volume (size)Size and mass of the left ventricle Left ventricular mass is a flawed proxy for ventricular systolic function and load. The mass is, however, an important parameter in the…
- Ejection fraction (EF): Physiology, Measurement & Clinical EvaluationVentricular ejection fraction (EF) For several decades, ejection fraction (EF) has been the dominating method for assessing left ventricular systolic function. Ejection fraction…
- Fractional shortening for estimation of ejection fractionFractional shortening (FS) for estimating systolic function Fractional shortening (FS) is calculated by measuring the percentage change in left ventricular diameter during…
