Diastolic heart failure

特許 係属中 Diastolic heart failure and diastolic dysfunction refer to the decline in performance of one (usually the left ventricle) or both (left and right) ventricles during diastole. Diastole is the cardiac cycle phase during which the heart is relaxing and filling with incoming blood that is being returned from the body through the inferior (IVC) and superior (SVC) venae cavae to the right atrium and from lungs through pulmonary veins to the left atrium.
