…If ventricular geometry is normal and there are no regional wall motion abnormalities, then fractional shortening correlates strongly with ejection fraction. Similar to ejection fraction…

…are elevated. Consequently, congestion may occur across the full range of left ventricular ejection fraction and may result from systolic dysfunction, diastolic dysfunction, or both…

…Currently, two dimensional (2D) echocardiography for calculation of ejection fraction is the dominant method for assessing left ventricular function (systolic function). It should be noted…

…will differ from the emitted sound waves. The change in frequency is referred to as the Doppler effect . The Doppler effect was first described in…

…contraction). Traditional methods for investigating left ventricular function — e.g ejection fraction (EF), fractional sorting (FS), etc — do not elucidate regional variations in contractile function…

…in ejection fraction that can be generated during exercise. Effect of preload and afterload on ejection fraction Ejection fraction is highly dependent on preload and…

…duration , sex , and genetically influenced effects on the cardiovascular system. Acute exposure produces transient haemodynamic and myocardial effects, whereas sustained heavy consumption is associated with…

…and age related changes in left ventricular filling contribute to susceptibility. Heart failure with preserved ejection fraction is regarded as a multifactorial systemic illness involving…

…and ejection fraction (EF) may be reduced because the end diastolic volume of the ventricle (EDV) is reduced. Constrictive pericarditis also leads to right sided…

Echocardiography Diastolic function and echocardiographic assessment The importance of systolic function can be understood on an intuitive basis. Consider the fact that the left ventricle…
