2. Diastolic function - Wikipedia

   en.wikipedia.org/wiki/Diastolic_function

   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] Due to the epidemic of heart failure, [3] particularly the cases determined as diastolic heart failure, it is increasingly urgent and ...

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

   Heart rate and rhythm - loss of a normal atrial rhythm (e.g., atrial fibrillation causes loss of the A wave). The height of the E wave becomes dependent on the length of the cardiac cycle (variable) rather than a measure of diastolic function. Similarly, pacing and tachycardia result in alterations, whereas bradycardia increases the E/A ratio.

6. Pathophysiology of heart failure - Wikipedia

   en.wikipedia.org/wiki/Pathophysiology_of_heart...

   In systolic dysfunction, the ejection fraction is decreased, leaving an abnormally elevated volume of blood in the left ventricle. In diastolic dysfunction, the end-diastolic ventricular pressure will be high. This increase in volume or pressure backs up to the left atrium and then to the pulmonary veins.

   Whereas your heart rate is the number of times your heart beats per minute, your blood pressure measures the force with which your blood circulates and stresses your artery walls. If you have high ...
