2. Diastolic function - Wikipedia

   en.wikipedia.org/wiki/Diastolic_function

   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]

3. Heart failure with preserved ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with...

   In either technique, the heart is evaluated for left ventricular diastolic function. Important parameters include, rate of isovolumic relaxation, rate of ventricular filling, and stiffness. [citation needed] Frequently patients are subjected to stress echocardiography, which involves the above assessment of diastolic function during exercise. [45]

4. E/A ratio - Wikipedia

   en.wikipedia.org/wiki/E/A_ratio

   The E/A ratio is a marker of the function of the left ventricle of the heart. It represents the ratio of peak velocity blood flow from left ventricular relaxation in early diastole (the E wave) to peak velocity flow in late diastole caused by atrial contraction (the A wave). [1]

5. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   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 ...

6. Ventricle (heart) - Wikipedia

   en.wikipedia.org/wiki/Ventricle_(heart)

   The left ventricular muscle must relax and contract quickly and be able to increase or lower its pumping capacity under the control of the nervous system. In the diastolic phase, it has to relax very quickly after each contraction so as to quickly fill with the oxygenated blood flowing from the pulmonary veins .

7. Cardiac output - Wikipedia

   en.wikipedia.org/wiki/Cardiac_output

   EF is the fraction of blood ejected by the left ventricle (LV) during the contraction or ejection phase of the cardiac cycle or systole. Prior to the start of systole, during the filling phase , the LV is filled with blood to the capacity known as end diastolic volume (EDV). During systole, the LV contracts and ejects blood until it reaches its ...
