Normally 75-80% of filling occurs in early diastole
. Around 15-20% occurs in atrial systole.
* A hypocalcaemia-induced acute coronary syndrome is most likely a function of the myocardium being perfused primarily during diastole
, with partial vasospasm limiting the diastolic flow during times of increased cardiac output or energy requirements.
During the systolic retraction of the thoracic wall, the veins were again gradually lifted and filled to a not insignificant degree (in the second case with a double motion, corresponding to the contraction of the atrium and ventricle), and at the moment of diastole
to collapse again to complete disappearances.
 In cardiovascular physiology, EDV is the volume of blood in the right and/or left ventricle at the end load or filling in (diastole
IVSTD = Interventricular Septum Thickness in Diastole
At 20 months of age, after about 18 months of ERT (without any side effects), echocardiography was repeated and demonstrated ejection fraction of 75%, interventricular septum diameter in systole of 7 mm (normal value=5-7 mm), interventricular septum diameter in diastole
of 6.5 (normal value=4.5-6.5 mm), and posterior wall diameter of 7 mm (normal value=4.5-7 mm).
Initial horizontal (also referred to as the "4 chamber") view of the heart in diastole
via echocardiography in the African grey parrot described in Figure 1.
The third phase is the D wave (second peak), representing early ventricular diastole
. At this time the AV valves open, atrial pressure decreases, and venous return increases a second time.
An ultrasonic measurement called the renal arterial resistive index (RI) can be calculated by determining the ratio of change in renal (kidney) blood flow velocity between systole (when the heart contracts) and diastole
(when the heart relaxes) to the systolic velocity.
However, the ventriculogram became one of the methods that allow to accurately assess the ventricular silhouette at the end of diastole
and systole, to determine possible morphological alterations and to estimate the left ventricular volumes and the ejection fraction (3).

and (b) systole (bar scale: one integer = 1 cm).
(iii) The LV geometry : end-diastolic diameter (LVEDD), indexed end-diastolic diameter (LVEDDi), indexed LV mass (LVMi), interventricular septal thickness during diastole
(IVSd), and LV posterior wall thickness during diastole
Diastolic heart failure or diastolic dysfunction refers to a decline in performance of one or both ventricles of the heart during diastole
, when the heart is filling with blood.
The basal RV linear dimension (RVbd) was defined as the maximal transverse dimension in the basal one-third of the RV inflow at end diastole
. The proximal RV outflow diameter (RVOTprox) was defined as the linear dimension measured from the anterior RV wall to the interventricular septal-aortic junction in the parasternal long-axis view at end diastole
The echocardiogram (Figure 1; Table 1) documented left ventricular dilation in both systole and diastole
, reduced fractional shortening (14%) and ejection fraction (30%), and an increased E-point septal separation (14.7mm), which suggested systolic myocardial failure with eccentric left ventricular remodeling.
