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...

   Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.

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. Restrictive cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Restrictive_cardiomyopathy

   Thickened LV walls (with normal chamber size) Thickened RV free wall (with normal chamber size) Elevated right atrial pressure (>12mmHg), Moderate pulmonary hypertension, Normal systolic function, Poor diastolic function, typically Grade III - IV Diastolic heart failure.

6. 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 ...

7. Ventricular hypertrophy - Wikipedia

   en.wikipedia.org/wiki/Ventricular_hypertrophy

   Electrocardiogram (EKG), a non-invasive assessment of the electrical system of the heart, can be useful in determining the degree of hypertrophy, as well as subsequent dysfunction it may precipitate. Specifically, an increase in Q wave size, abnormalities in the P wave , as well as giant inverted T waves , are indicative of significant ...
