Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
In normal subjects, the left ventricular ejection fraction (LVEF) should be about 50% [9] (range, 50-80%). There should be no area of abnormal wall motion (hypokinesis, akinesis or dyskinesis). Abnormalities in cardiac function may be manifested as a decrease in LVEF and/or the presence of abnormalities in global and regional wall motion.
Ejection fraction: 66% (± 6%) [2] 67% (± 4.6%) [3] Heart rate: 60–100 bpm [4] 60–100 bpm [4] Cardiac output: 4.0–8.0 L/minute [5] 4.0–8.0 L/minute [5]
End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.. ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle.
The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (LVEF) of the heart. This scan is done in conjunction with a cardiac stress test. The diagnostic information is generated by provoking controlled regional ischemia in the heart with variable perfusion.
In clinical cardiology the term "diastolic function" is most commonly referred as how the heart fills. [1] Parallel to "diastolic function", the term "systolic function" is usually referenced in terms of the left ventricular ejection fraction (LVEF), which is the ratio of stroke volume and end-diastolic volume. [2]
The left ventricular systole enables blood pressure to be routinely measured in the larger arteries of the left ventricle of the heart. LV systole is volumetrically defined as the left ventricular ejection fraction (LVEF). Similarly, RV systole is defined as the right ventricular ejection fraction (RVEF).
The principal benefit of LV shear strains is amplification of the 15% shortening of myocytes into 40% radial LV wall thickening, which ultimately translates into a >60% change in LV ejection fraction. Left ventricular shearing increases towards the subendocardium, resulting in a subepicardial to subendocardial thickening strain gradient.
