It is more distinct when the heart is hypertrophous and dilated; and, under these circumstances, I have found the jogs correspond with the ventricular systole
and diastole respectively, that of the diastole being sometimes nearly as strong as the other, and having the character of a receding motion suddenly arrested...
The three steady flow rates simulated onset ventricular systole
(5L/min), mid-systole (15L/min), and peak systole
(25 L/min) .
Ductus venosus wave form assessment methods Indices Method Consecutive cardiac event Pulsatility index Reflects deterioration in forward for vein cardiac function Systolic velocity Semi quantitative Cannot identify which component of - End diastolic forward cardiac function was velocity deteriorated (preload, contractility/compliance or afterload) Time average maximum velocity A-wave assessment Visual Impaired atrial contraction Velocity ratios S/v Forward flow into atria during end-systole v/D Ventricular relaxation D/a Ratio Passive and active diastolic filling S/D Ventricular systole

Measured variables are left ventricular longitudinal length in systole
(LVLS) and diastole (LVLD).
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).
However, left ventriculography revealed apical ballooning akinesis with basal hyperkinesis during systole
and reduced ejection fraction [Figure 2].
Pressure gradients were measured, followed by right ventricular angiography in lateral projection to measure the diameter of the pulmonary valve annulus in systole
. The valvuloplasty balloon was centred on the annulus valve and inflated until complete resolution of the waist.
The concentric LV hypertrophy was the most important echocardiographic finding in HCM observed in present study leading to increased in thickening of walls, the left ventricular wall thickening during both diastole and systole
was the main observation.
The highest level is at the peak systole
of the first cardiac cycle t = 0.65 s.
(16) designed a new methodology based on fractal geometry that includes the creation of the concept of degrees of similarity, which allows the comparison of the fractal dimensions of the ventricular contours in systole
, diastole and totality from images with a diagnosis of cardiac ventricular normality and severe abnormality.

showing basal and apical ballooning with preserved contractility of the mid ventricular segments.
Left ventricle obliteration during systole
, visualized in the parasternal short axis view at the papillary muscle level, suggests hypovolemia (CHACKO & BRAR, 2014).
