In clinical cardiology the term "diastolic function" is most commonly referred as how the heart fills. 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. Due to the epidemic of heart failure, particularly the cases determined as diastolic heart failure, it is increasingly urgent and crucial to understand the meaning of “diastolic function”. Unlike "systolic function" which can be simply evaluated by LVEF, there are no established dimensionless parameter for "diastolic function" assessment. Hence to further study "diastolic function" the complicated and speculative physiology must be taken into consideration.
